Kubuntu 8.04 LTS (Hardy Heron)


  • On April 24, 2008 Kubuntu 8.04 was released.
  • It is code named Hardy Heron and is the successor to Kubuntu 7.10 Gutsy Gibbon (Gutsy+1).
  • Hardy Heron is an LTS (Long Term Support) release. The desktop will be supported with security updates until April 2011 (and the server will be supported until April 2013).

How to find out what version of Kubuntu you're using

In Konsole type:

lsb_release -a
uname -a

Newer Versions of Kubuntu

  • Kubuntu has a six month release cycle, with releases in April and October
  • Maverick Meerkat (10.10), released in October 2010. This is not an LTS version.
  • Lucid Lynx (10.04 LTS), released in April 2010, is the next LTS (Long Term Support) version.
  • Karmic Koala (9.10), released in October 2009. This is not an LTS version.
  • Jaunty Jackalope (9.04), released in April 2009. This is not an LTS version.
  • Intrepid Ibex (8.10), released in October 2008. It is no longer supported.
  • Hardy Heron (8.04 LTS) is an LTS (Long Term Support) release.

Older Versions of Kubuntu

  • Gutsy Gibbon (7.10) (no longer supported)
  • Feisty Fawn (7.04) (no longer supported)
  • Dapper Drake (6.06 LTS) (Desktop no longer supported. Server support until June 2011.)

General Notes

  • Kubuntuguide is unofficial and is not associated with Canonical Ltd.
  • Kubuntu allows a user to accomplish tasks from either a menu-driven Graphical User Interface (GUI) or from a text-based command-line interface (CLI). In Kubuntu, the command-line-interface terminal is called Konsole, which is started: K-> System -> Konsole.
In this guide, text inside the grey dotted box like this should be put into a Konsole terminal.
  • Many changes to the operating system can only be done by a User with Administrative privileges. 'sudo' elevates a User's privileges to the Administrator level temporarily (i.e. when installing programs or making changes to the system). Example:
sudo bash
  • 'kdesudo' should be used instead of 'sudo' when opening a Graphical Application (such as the graphical text-editor application kate) through the "Run Command" dialog box or the CLI. Example:
kdesudo kate /etc/apt/sources.list
  • "man" command can be used to find the help manual for a specific CLI command. E.g. "man sudo" will display the manual page for the "sudo" command. Example:
man sudo
  • While "apt-get" and "aptitude" are fast ways of installing programs/packages, you can also use the Adept Package Manager (K -> System -> Adept Manager), a GUI method for installing programs/packages. Most programs/packages available with apt-get install will also be available from the Adept Package Manager. In this guide, when you see
apt-get install package
you can simply search for package in Adept and install it that way. The GUI installer K -> Add/Remove Programs can also be used to install programs/packages (but not all programs/packages are available from this GUI).
  • Many instructions use the text editor "nano" (which is universally available in Linux). However, it is often easier to use the text editor "kate" in Kubuntu instead.
  • "K" or "K menu" means the bottom-left (or upper-left) button, akin to the Start button in Microsoft Windows®.
  • If you are using the 64-bit version, replace any "i386" with "amd64".

Installing Kubuntu

Hardware requirements

Kubuntu Hardy Heron runs well with as little as 384 Mb RAM. (The installer requires a minimum of 256 Mb RAM, while the alternative installer can run using only 192 Mb RAM.)

The install takes between 3-4 Gb hard drive space, and 8-10 Gb will be needed to run comfortably.

If you have an older computer with less memory than this, consider Xubuntu (if between 256 Mb and 512 Mb RAM) or PuppyLinux or DSL (if less than 256 Mb RAM).

Fresh Installation

Download the latest ISO image from Kubuntu 8.04. See this guide for burning the ISO image to a CD ("LiveCD").

Use the CD for installation.

Dual-Booting Windows and Kubuntu

Rarely, a user may experience problems dual-booting Kubuntu and Windows. In general, a Windows OS should be installed first, because its bootloader is very particular. A Windows installation usually occupies the entire hard drive, so the partition needs to be shrunk, creating free space for the Kubuntu partition. (You should clean up unnecessary files and defragment the drive before resizing.) The Windows partition can be resized from within Windows Vista using the shrink/resize option in the Administrative Tools --> Disk Management tool. If using Windows XP (or other Windows OS), use GParted partition manager to shrink the Windows partition and thereby leave free space on the hard drive for the Kubuntu partition. If done this way, there is no problem installing Kubuntu as the second operating system and it is done automatically from the Kubuntu LiveCD. Allow the Kubuntu LiveCD to install to "largest available free space."

A Windows partition should be at least 20 Gb (recommended 30 Gb), and a Kubuntu partition at least 10 Gb (recommended 20 Gb). Obviously, if you have plenty of disk space, make the partition for whichever will be your favoured operating system larger. For a perspective on other partitioning schemes, see this Psychocats Guide to Partitioning.

Alternatives include:

  • Wubi (Windows-based Ubuntu Installer), an officially supported dual-boot installer that allows Ubuntu to be run mounted in a virtual-disk within the Windows environment (which can cause a slight degradation in performance). Because the installation requires an intact functioning Windows system, it is recommended to install Ubuntu in this manner for short-term evaluation purposes only. A permanent Ubuntu installation should be installed in its own partition, with its own filesystem, and should not rely on Windows.
  • EasyBCD, a free Windows-based program that allows you to dual-boot Windows Vista and Ubuntu (as well as other operating systems) by configuring the Vista bootloader.

Upgrading Gutsy to Hardy

If you are using an older version of Kubuntu, you should consider upgrading to Hardy.

You can only directly upgrade to Kubuntu 8.04 (Hardy Heron) from Kubuntu 7.10 (Gutsy Gibbon). If you have a version older than Gutsy (7.10) then you must do serial upgrades. (For example, if you are still using Feisty, you must upgrade from Feisty to Gutsy, and then from Gutsy to Hardy.)

To upgrade from Gutsy Gibbon 7.10 to Hardy Heron 8.04:

  1. KMenu -> System -> Adept Manager (Manage Packages) -> Manage Repositories
  2. Enable the "Recommended updates" and "Pre-released updates" repository
  3. Version Upgrade --> Fetch Updates
  4. Click the Full Upgrade button

KDE Eye-Candy Resources

Kubuntu Screenshots and Screencasts

New Applications Resources

  • KDE Apps
  • GetDeb - Features the latest versions of software available from the official repositories as well as software not available in the official repositories. Available in easy-to-install .deb files (see Apt and Package Basics).

Other *buntu guides and help manuals

  • Ubuntuguide -- Ubuntu uses the Gnome desktop.
  • Xubuntu Desktop Guide -- Xubuntu can run with as little as 256 Mb RAM. It is better for older machines with limited resources. It uses the XFCE desktop.

Add Extra Kubuntu Repositories

Software packages and programs are freely available for download at multiple online sites with standardized structures, called repositories. There are repositories officially sanctioned and monitored by the Kubuntu/Ubuntu developer community, while other repositories are independently provided, without official sanction or supervision (and should be used with caution). Additional information is available from the Kubuntu Repository Guide.

Types of Repositories

  • There are four major package repository types in Kubuntu:
  • main - Supported and supervised by Canonical. This is the major part of the distribution.
  • restricted - Software not licensed under the GPL (or similar software license), but supported and supervised by Canonical.
  • universe - Software licensed under the GPL (or similar license) and supported by users.
  • multiverse - Software not licensed under the GPL (or similar license), but supported by users.
  • There are also these additional types of repositories:
  • hardy-updates - Updates to official packages.
  • hardy-backports - Current version software from Hardy+1 (Intrepid Ibex) that has been backported to Hardy Heron.
  • hardy-proposed - Proposed updates & changes (bleeding edge stuff).

Third party repositories

Software developers often maintain their own repositories, from which software packages can be downloaded and installed directly to your computer (if you add the repository to your list). Many of these third party repositories and software packages have never been reviewed by the (K)Ubuntu/Debian community and can present a security risk to your computer. Trojans, backdoors, and other malicious software can be present at any unregulated repository. When using repositories not endorsed by the (K)ubuntu/Debian community, make sure you have utter confidence in that site before enabling the repository and installing a software package from it.

Add Repositories using Adept Package Manager

This is the preferred method.

  • K menu -> System -> Adept Manager -> Manage Repositories.
  • Here you can enable the repositories for Kubuntu Software and Third Party Software.
  • For Third Party Software select Add... -> enter the repository's address. It will have a format similar to:
deb http://archive.ubuntu.com/ubuntu/ hardy main restricted
deb-src http://archive.ubuntu.com/ubuntu/ hardy main restricted
  • Example: To add the Medibuntu repository, Add:
deb http://packages.medibuntu.org/ hardy free non-free
  • Download the repository key to a folder.
  • Example: The Medibuntu key can be downloaded from
  • Then add the key from:
Adept -> Sources -> Edit Software Sources -> Authentication -> Import Key File...
  • (Alternatively, you can manually add the key from the Konsole command line terminal. See Add Repository keys.)
  • Refresh the package list from the new repository:
Adept -> Adept -> Apply Changes, then Fetch Package list

Manually add repositories

  • Do this at your own risk. Modify the default Kubuntu sources.list only if you understand what you're doing. Mixing repositories can break your system. For more information see the Ubuntu Command-line Repository guide.
  • Create a backup of your current list of sources.
sudo cp -p /etc/apt/sources.list /etc/apt/sources.list_backup

Note: sudo - runs the command with root privileges. cp = copy. -p = prompt to overwrite if a file already exists.

  • Edit the list of sources:
sudo nano /etc/apt/sources.list
or using a graphical editor:
kdesu kate /etc/apt/sources.list
  • Note: To use your local mirror you can add "xx." before archive.ubuntu.com, where xx = your country code.
Example: deb http://gb.archive.ubuntu.com/ubuntu hardy main restricted universe multiverse indicates a repository for Great Britain (gb).
  • Here is a sample sources.list. At the end have been added repositories for Medibuntu:
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.

  • Refresh the packages list from the new repositories:
sudo apt-get update

Add repository keys

  • Download the gpg keys for the repositories and automatically add them to your repository keyring:
  • Example: To obtain and add the Medibuntu repository key:
wget --quiet http://packages.medibuntu.org/medibuntu-key.gpg -O - | sudo apt-key add -
  • Example: To obtain and add the Google repository key:
wget --quiet https://dl-ssl.google.com/linux/linux_signing_key.pub -O - | sudo apt-key add -

Note: wget - retrieves a file from a network location. --quiet = no output. -O - = Output downloaded item to the screen. The | (pipe symbol) is used to capture the output from the previous command and use it as an input for the piped command (i.e. apt-key, which adds it to the keyring).

Kubuntu Updates

Apt and Package Basics

Here is some basic information on how to use the APT package management tools from a terminal. The functionality of these tools is also provided in Adept Manager's GUI, but many people prefer to use the terminal to save time or for other reasons.

Open up a Konsole terminal (K -> System -> Konsole)

  • Installing packages
sudo apt-get install <packagename>
    • Examples:
sudo apt-get install mpd sbackup
  • Removing packages
sudo apt-get remove <packagename>
    • To remove all dependencies type
sudo apt-get autoremove
    • Examples:
sudo apt-get remove mpd sbackup
  • Searching for packages
sudo apt-cache search <keywords>
    • Examples:
sudo apt-cache search Music MP3
sudo apt-cache search "Text Editor"
  • Updating Apt database (used after adding/removing Apt repositories)
sudo apt-get update
  • Upgrading packages
sudo apt-get upgrade
  • Upgrade entire distribution
sudo apt-get dist-upgrade
  • Install downloaded Ubuntu/Kubuntu (Debian) package (.deb)
sudo dpkg -i package.deb
  • Remove Kubuntu/Ubuntu (Debian) package
sudo dpkg -r package
  • Reconfigure/Repair installed package
sudo dpkg-reconfigure packagem
    • Examples:
sudo dpkg-reconfigure mpd
  • Handling ".tar.gz" (Tar/GZip) and ".tar.bz2" (Tar/Bzip2) Archives
    • To extract:
tar xvf package.tar.gz

Command explained: tar is an application which can extract files from an archive, decompressing if necessary.

-x means extract. -v means verbose (list what it is extracting). -f specifies the file to use. (You could extract this package by first using the command gunzip (for .gz) or bunzip2 (for .bz2), and you would be left with a .tar file.)

    • To create .gz:
tar cvfz package.tar.gz folder
    • To create .bz2:
tar cvfj package.tar.bz2 folder

Note - bz2 is a newer, more efficient compression method.

  • Decompressing ".bz2" files
bunzip2 file.bz2
  • Decompressing ".gz" files
gunzip file.gz
  • Building from Source

Make sure you have all the necessary development tools (i.e. libraries, compilers, headers)

sudo apt-get install build-essential
sudo apt-get install linux-headers-`uname -r`

"uname -r" lists the current kernel you are using.

Extract your package (as detailed above)

tar xvf package.tar.gz

Commence the build process

cd /path/to/extracted/package
sudo make install

Note - typing ./ before a filename in the current folder allows unix to try and execute the file as an application even if it is not in the set of folders (known as the path) which it searches when you type a command name. (The current folder is not in the path for security reasons.) If you get "permission denied" the file is not marked as being executable, which sometimes happens if packages have not been created properly. To fix this:

chmod +x filename

If build is successful, consider making an Ubuntu (Debian) package (.deb) for future use:

Install package tools:

sudo apt-get install checkinstall

Rebuild package using "checkinstall":

cd /path/to/extracted/package

Keep the resulting ".deb" file for future use. It can be installed using:

sudo dpkg -i package.deb

Note: These are basic instructions that may not always work. Some packages require additional dependencies and optional parameters to be specified in order to build them successfully.


aptitude is a terminal-based package manager that can be used as a drop-in replacement for apt-get. One of the main features of aptitude is that it marks packages that are automatically installed and removes them when no packages depend on them. This makes it easy to remove applications completely. To use Aptitude, replace apt-get with aptitude in the command line. Examples:

sudo aptitude install <packagename>
sudo aptitude remove <packagename>
sudo aptitude update
sudo aptitude upgrade

For an ncurses-based user interface, type

sudo aptitude

For more information, see the aptitude documentation.

Manual Updates

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade


Use Adept Update Manager: K > System -> Adept Manager -> Fetch Updates > Full Upgrade

Automated Updates

  • Open K menu.
  • In the System menu, open Adept Manager.
  • In the Adept menu, select Manage Repositories.
  • Open the Updates tab at the top of the screen.
  • Make sure Check for Updates has an X in the box.
  • Use the selection box to the right of that to determine how often you'd like to check for updates.
  • Click the close button.
  • Close Adept Manager.

Add/Remove Programs

  • K menu -> Add/Remove Programs
  • Search for the sort of program you want to add. Example: type MP3 to see a list of mp3 software.
  • Check the box next to the software.
  • Click the "Apply Changes" button.
  • The selected program(s) will be automatically installed.

Kubuntu Addon Applications

sudo apt-get install bibletime

Zekr (Quran)

Zekr is an Islamic Quran Software. It has translations in many languages from authentic authors.

sudo apt-get install zekr

Proprietary Applications

Proprietary software helps you maximize your Internet experience, but is not open source. The software available includes Multimedia Codecs, Java Runtime Environment, and plug-ins for Firefox and Konqueror.

Restricted Extras

The Kubuntu Restricted Extras will install Adobe Flash Player, Java Runtime Environment (JRE) (sun-java-jre) with Firefox and Konqueror plug-ins (icedtea), a set of Microsoft Fonts (msttcorefonts), multimedia codecs (w32codecs or w64codecs), mp3-compatible encoding (lame), FFMpeg, extra multimedia codecs for K3b, the package for DVD decoding (libdvdread3, but see below for info on libdvdcss2), and the unrar archiver. This is a single command approach.

sudo apt-get install kubuntu-restricted-extras

You could also use Ubuntu Restricted Extras, but it installs plugins for the Gstreamer platform (the default in Gnome) and does not install the K3b codecs, so it is not recommended.

sudo apt-get install ubuntu-restricted-extras

Eye Candy Applications

Eye Candy Applications refer to the decoration of the Interface. These can be added on icons, themes, wallpapers etc. As well as the 3D effects that are available with the use Compiz Fusion.

Compiz Fusion

sudo apt-get install compiz-core compiz-fusion-plugins-extra compiz-fusion-plugins-main compiz-plugins libcompizconfig0 compiz-kde compiz-plugins compizconfig-backend-kconfig compizconfig-settings-manager kicker-compiz kicker-taskbar-compiz

Before starting Compiz you will have to make some changes so that the Desktop Preview & Pager and the Taskbar behave correctly. Open Kcontrol(alt+f2 then type in 'kcontrol') and navigate to Desktop >> Multiple Desktops and change the number of desktops to 1. Close Kcontrol and remove the Desktop Preview & Pager and the Taskbar from the panel. Right click on the panel and select 'Add Applet To Panel'. Add 'Desktop Preview & Pager - Compiz' and 'Taksbar - Compiz' to replace the old ones.

Note: in KDE 4.1 there is a Plasma that replaces Kicker so there is no way how you can install those applets. In this case the installation command will be as follows:

sudo apt-get install compiz-core compiz-fusion-plugins-extra compiz-fusion-plugins-main compiz-plugins libcompizconfig0 compiz-kde compiz-plugins compizconfig-backend-kconfig compizconfig-settings-manager

Note: if the Compiz Settings Manager you do not see any icons then you might want to install librsvg2-common which fixes this bug

sudo apt-get install librsvg2-common

To start Compiz

compiz --replace

Fusion Icon

Fusion Icon is a tray icon that allows you to easily switch between window managers, window decorators, and quick access to the settings manager

sudo apt-get install fusion-icon


Emerald is an alternative window decorator that provides more features and integration with Compiz.

sudo apt-get install emerald

To start Emerald

emerald --replace

Kicker-Applets (Extra Applets for the Panels) in KDE3

sudo apt-get install kicker-applets

Use by right clicking a panel > Add Applet To Panel

Note: This will not work for KDE4 as there is Plasma which replaces Kicker

Google Desktop

Download .deb file from Google Desktop Download Website

Browse to the file location:

cd <location>


cd /home/username/Desktop

Install by running:

sudo dpkg -i google-desktop-linux_current_i386.deb

Kicker-Kickoff (Suse Style K Menu)

The original Kicker-Kickoff program was first made available at kde-apps.org by Ruffinius. Currently he supports KickerQT but due to dependency problems many cannot install this more updated version on any Kubuntu release. Kicker-Kickoff has since been removed from kde-apps.org. Fortunately Technoshaun (The contributor of this piece) makes Kicker-Kickoff 1 a part of all his KDE theme packages at kde-look.org. If you download any of the KDE theme packages he has made available and unpack the tarball inside is a folder labled kicker_kickoff_1 with kicker-kickoff_1_i386.deb inside. Here is a cut from his readme file on istalling Kicker Kickoff:

Kicker_Kickoff_1 is the original Kubuntu kickoff package from Ruffinius. It is included for those who cannot install KickerQT due to conflicts or other issues. Though not as pretty it does work. It will also work on Mepis (except Mepis 7.0) and other Debian/Kubuntu based distros running KDE 3.5.5 through 3.5.8, provided dependencies can be met.

In the "kicker_Kickoff_1" folder use the command "sudo dpkg -i kicker-kickoff_1_i386.deb" (or other appropriate install method) then use the command "sudo dcop kicker kicker restart" to start the kickoff menu interface.

FFMPEG video / audio conversion

FFMPEG is the swiss-army knife of video and audio format conversion. It succeeds when no other program can. It is free and open source. If it not yet installed on your system as part of another package (it is used by many video/audio editors), then install it:

sudo apt-get install ffmpeg

To convert many different formats, read the FFMPEG documentation.

Example: To convert a saved Flash video (.flv) to an Mpeg-2 format playable on a DVD, convert:

ffmpeg -i samplevideo.flv -target ntsc-dvd samplevideo.mpg

Then use K3b to write the mpg file to a New DVD Data Project.

  • For PAL use -target pal-dvd. For widescreen, add the parameter -aspect 16:9 (but see these tips). For other conversion tips, see this forum. (Note: Most Flash video has very low resolution, with a screen size of 360x240, for example. You may see a slight diminishment in resolution if you wish to convert it to 720x480, which is the NTSC standard size. You can keep the original resolution by omitting the -target ntsc-dvd parameter.)


WinFF is a free, GPL-licensed open source GUI frontend for FFMPEG. See the website for installation instructions.

Zoneminder surveillance system

Zoneminder manages surveillance cameras and stores images on the hard disk. Images can be viewed using a (LAMP) server remotely. X10 devices can be triggered using built-in perl scripts. For more info see the Zoneminder website.

Installing the latest Zoneminder version
  • Minor tweaks are required to install the latest version of Zoneminder on Hardy. See the Zoneminder forums.
Using the repository package
  • There is a Zoneminder package for Hardy (that was the package from Gutsy). You should be able to install the package from Synaptic Package Manager.
Original Feisty installation instructions
  • However, if that does not work, try the original instructions that worked for Feisty:
  • You must have the LAMP server installed. In addition, you will need additional modules:
sudo apt-get install ffmpeg libarchive-tar-perl libarchive-zip-perl libdate-manip-perl libdevice-serialport-perl
sudo apt-get install libjpeg62 libmime-perl libstdc++6 libunwind7 libwww-perl zlib1g
  • Download the .deb package from the package manager's website:


  • Install using the Debian package manager. (No other method seems to work.)
dpkg -i zoneminder_1.22.3-8_i386.deb
  • (Note: If some dependencies are still unsatisfied, make sure you have these packages installed):
sudo apt-get install libc6 libc6.1 libgcc1 libgcc4 libstdc++6
(These should already be installed as part of the LAMP installation):
sudo apt-get install apache2-mpm-prefork libapache2-mod-php5 libmysqlclient15off mysql-client mysql-server php5  php5-mysql
Setup Zoneminder configuration

If your installation is successful, you will now need to set up the configuration files and databases for Zoneminder.

  • Copy the configuration file and restart the Apache2 server.
sudo ln -s /etc/zm/apache.conf /etc/apache2/conf.d/zoneminder.conf
sudo /etc/init.d/apache2 reload
  • View Zoneminder from your web browser:
  • Set up a MySQL database for Zoneminder
If this is the first time you have used MySQL, the default global MySQL superuser root will not have a password. You should set one now. Instructions for setting mySQL initial privileges are here.
In short:
mysql -u root
mysql> UPDATE mysql.user SET Password=PASSWORD('your_new_password') WHERE User='root';
mysql> quit
In addition, you can set up an additional global MySQL user (such as mysql_user, for example) by following the instructions here. That way you can reserve root login for emergencies.
In short:
mysql -u root
mysql> CREATE USER 'mysql_user'@'localhost' IDENTIFIED BY 'mysql_user_passwd';
mysql> quit

Now you must create a MySQL database for use by Zoneminder. This is an administrative MySQL command, so you must use one of your global MySQL users (either root or mysql_user, as created in the example above). You can name your Zoneminder database anything you want, instead of zmdatabase.

mysqladmin -u root -p CREATE zmdatabase


mysqladmin -u mysql_user -p CREATE zmdatabase

Create users for the Zoneminder database. As always, I create a root user for emergency use. I use the same password for root as I do elsewhere on my system. Then I also create a user named zm_user (but you could also creat a user named mysql_user, to keep everything consistent). [I use a unique user here because this is a home security system, after all, and I don't want it breached.] These users are specific to this database; they can be the same users as used elsewhere in the system or can be unique users.

TO  'zm_user'@'localhost' IDENTIFIED BY 'password';

TO   'root'@'localhost' 
IDENTIFIED BY 'password'; (I used my usual root password here).
mysql> quit
mysqladmin reload

Note: mysql commands (i.e. any entered at the mysql> prompt) must end with a semicolon. If you forget the semicolon, nothing will happen.

Myth Zoneminder

MythZoneminder allows you to view your security cameras through Myth TV, essentially. It is a plugin that interfaces the two packages Zoneminder (which must be working on your system) and Myth TV (which must also be working.) See the installation instructions.

It can be found in Adept as the mythzoneminder package.

sudo apt-get install mythzoneminder

dd (disk backup)

dd is a *nix command that enables the copying of files or an entire disk using a single command. Parameters must be precisely specified to avoid risk of accidentally erasing data. See these brief instructions or these instructions for detailed options. You cannot copy a hard drive that contains the operating system you are currently running. Instead, boot into a LiveCD and run the dd command that way. An example command to copy Hard drive X to Hard drive Y is:

dd if=/dev/hdx of=/dev/hdy
  • ddrescue is a variation of the dd command that allows working with potentially corrupted datasets, partitions, or hard drives.

Run Kubuntu LiveCD from a USB pendrive

The Kubuntu LiveCD can be installed on and run from a USB pendrive. Settings can be "persistently" saved (but the LiveCD kernel modules can not be upgraded). Programs can be installed and run, however, and files saved to the USB drive. (The installed programs will remain installed). See these Pendrivelinux instructions. A Kubuntu Live CD is needed to do the install.

The USB "LiveCD" can also be used to install Kubuntu on computers (including netbooks) that do not have CD-ROM/DVD drives.

USB pendrives to be used to run Kubuntu should have a minimum of 2 Gb (preferably 4 Gb). If you wish to install a fast, fully functional Linux system on a pendrive that has less memory than that, use PuppyLinux.

Create a boot CD to allow booting from the USB drive

Many computers do not allow booting from a USB drive (but they do allow booting from the CD-ROM). You can create a CD-ROM using these Pendrivelinux instructions and set your BIOS to boot from this CD-ROM. When you boot from this CD-ROM, it will use the bootup files on the Kubuntu USB drive you previously created (in the step above).

KNemo (Network interfaces monitor for systray)

sudo apt-get install knemo

KDE or the K Desktop Environment, is a network transparent contemporary desktop environment for UNIX workstations. It is supported by the KDE Project team having HQ site on http://www.kde.org


KDE 3 is an extremely mature platform with a wide range of third party applications and distribution support, and may be attractive to some use cases.


KDE 4, the next major incarnation of the KDE desktop, was released on the 11th of January 2008. With completely redesigned frameworks and libraries, KDE 4 is a major step forward from the KDE 3 series. KDE 4 includes the new desktop shell Plasma, built in compositing for desktop effects and many application improvements.

How to install KDE 4.1.1

The updated packages for Kubuntu 8.04 are located in the Kubuntu Member's KDE 4 Personal Package Archive (PPA) repositories. To update to KDE 4.1.1, please follow these instructions:

1) Follow the Kubuntu Repository Guide and add the following to your 'Third-Party Software' tab:

deb http://ppa.launchpad.net/kubuntu-members-kde4/ubuntu hardy main

2) You can now update any existing KDE 4 installation to the most recent version using the Adept Updater tool in your system tray.

3) Install the package called kubuntu-kde4-desktop, if you are still running KDE 3 and want to install KDE 4 along your current desktop

sudo apt-get install kubuntu-kde4-desktop

4)Now you should be able to select your new KDE 4 desktop as session in your login manager. In KDM for example: Click the Session Type option and select KDE 4, then proceed with the usual login steps.

Note: kdeplasma-addons contains new Plasma fun.

Monitors / Displays

Configure Dual Monitors with nVidia

Please make sure that the nVidia driver has been installed and is functioning properly on your first screen. Also, make sure both monitors are connected.

We will use the NVIDIA X Server Settings application to do all of the work. This can be found in K->System Settings. However, we will need to be root to make the configuration stick. So we will launch it from a terminal. Open Konsole and type:

sudo nvidia-settings

Then select "X Server Display Configuration". You should see 3 boxes (2 if your card doesn't have an S-Video out). From here you can configure all of your card's outputs. Select the "(Disabled)" box and hit "Configure..." below. The most common choice is TwinView. Select it and hit OK.

Now, take the time to setup the desired screen resolutions and positions of your two active displays. The new display will likely have resolution set to "Auto" to match your first. Feel free to change this if you wish. Leave the first screen's position as "Absolute" and set your second display's position relative to that. "Clone" means the same output on both.

Once you are satisfied with your settings, hit Apply to test them. Note: if your displays are side-by-side, the kicker may extend across both screens as well as any maximized applications. This will be corrected when the X server is restarted. If everything else is ok, hit "Save to X Configuration File". Now hit Ctrl+Alt+Backspace to restart X. You now have 2 screens!

Troubleshooting: if the X server fails to reload you can recover your old X configuration. In a terminal:

sudo cp /etc/X11/xorg.conf.backup /etc/X11/xorg.conf

Optical Drives


Printers & Scanners

The new CUPS interface recognizes many printers. Specific printers not recognized can often be installed using instructions found at the Linux Foundation OpenPrinting database.



For Synaptics Touchpads:

sudo apt-get install ksynaptics


Wireless Cards

Atheros Cards

The Atheros 802.11 b/g integrated card on my laptop did not work until I installed drivers manually.

  • Extract the files
  • Make sure your linux headers and build-essential packages are installed:
sudo apt-get install build-essential
sudo apt-get install linux-headers-$(uname -r)
  • Unload any drivers already running.
ifconfig ath0 down
ifconfig wifi0 down
  • Change to the directory where you extracted the driver.
cd <directory_where_driver_unzipped>
  • From that directory, run the installation scripts:
cd scripts
./find-madwifi-modules.sh $(uname -r)
cd ..
  • Complete the installation by compiling the source and installing it.
make install
  • Add the installed drivers to your system.
modprobe ath_pci

Following this, Network Manager was able to see the wireless card and I was able to configure everything elese (WEP key, etc.) from there.

Complete instructions are available at MadWifi UserDocs.

Note: Because this is a manual installation of a driver, I have to repeat these steps every time the kernel is upgraded.



Tux Mobil has a list of Linux applications for use with GPS devices, and compatible hardware. Two GPS packages are available from the Ubuntu/Kubuntu respositories:

Samba File Sharing

Enable File Sharing Server With User Login (Very Reliable Method)

Do the following on the machine that has the files to be shared:

Install Samba

sudo apt-get install samba

Add current user to Samba:

sudo smbpasswd username

(replacing username with your login username)

Open the samba config file:

sudo nano /etc/samba/smb.conf

Add the directories to be added (right at the end) in the following format:

path = /home/username/FOLDER_TO_BE_SHARED

(Replace username with your username and FOLDER_TO_BE_SHARED with the folder you want to share)

Press CTRL+X and then Y to save.

Restart Samba

sudo /etc/init.d/samba restart

On Windows access the folder in the following format in Windows Explorer:


(replacing 192.168.x.x with your actual IP address of the server serving the folder)

On Linux type the following in Konqueror or Nautilus:


(replacing 192.168.x.x with your actual IP address of the server serving the folder)

Note: If you use Sharing in KDE's System Settings panel, be aware there's a small bug, reported here: https://bugs.launchpad.net/ubuntu/+source/kdenetwork/+bug/95452 To summarize, you need to comment out/delete any instances of these two lines in /etc/smb.conf :

case sensitive
msdfs proxy
Recognizing Win98 machines

Microsoft networking is extremely quirky. To enable recognition of PCs with Windows 98, edit your Samba configuration file:

sudo nano /etc/samba/smb.conf

Then add the following lines to the file:

client lanman auth = yes
client ntlmv2 auth = no

Local Area Network

Modems / Dial-up

While previously one had to use scanModem tool to find out what kind of software modem he/she was using, now it works out of the box, after you accept to use restricted drivers.

For dialing, use KPPP application.


There are two applications you might try:

knetworkmanager (default Wireless Manager in Kububtu Gutsy)


sudo apt-get install kwifimanager

KWifiManager only supports WEP encryption.

Manual configuration

3 steps for WEP:

sudo iwconfig eth[N] essid [SSID]
sudo iwconfig eth[N] key restricted s:[PASSWORD]
sudo dhclient

WPA is more complicated:

mkdir /etc/wpa_supplicant
cd /etc/wpa_supplicant
echo network = { > wpa_supplicant.conf
echo ssid="SSID" >> wpa_supplicant.conf
echo key_mgmt=WPA-PSK >> wpa_supplicant.conf
echo psk="PRESHAREDKEY" >> wpa_supplicant.conf
echo } >> wpa_supplicant.conf
cd /etc/network
vim interfaces

Now add after "auto eth[N] ..." & "iface eth[N] .." (press 'i'):

wpa-driver wext # or whatever driver your network card needs
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

Save the file ('Esc', ':x', 'Enter') and restart your system.

Remote Access



OpenVPN is a free, GPL-licensed open-source cross-platform VPN solution based on SSL (not IPSec). Install:

sudo apt-get install openvpn bridge-utils


Secure Shell or SSH is a network protocol that allows data to be exchanged over a secure channel between two computers. Encryption provides confidentiality and integrity of data. SSH client is installed by default in Feisty so you can connect to another computer running SSH server, while if you want to run an SSH server you have to install it:

   sudo apt-get install openssh-server



  • XDMCP is not secure over the Internet. It is turned off by default in Kubuntu. To enable it, edit the KDE configuration file:
kate /etc/kde3/kdm/kdmrc
  • Find and change the line from false to true so that it reads:


Virtual Network Computing (VNC) is a graphical desktop sharing system which uses the RFB protocol to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction, over a network. VNC is platform-independent — a VNC viewer on any operating system can usually connect to a VNC server on any other operating system.

On Kubuntu, a VNC viewer is installed by default under K-Menu -> Internet -> Krdc To connect to a vnc server, simply type vnc:/SERVER_IP_ADDR

You can also install XVNC4Viewer if you prefer it over Krdc using:

   sudo apt-get install xvnc4viewer

To install a VNC server to share your desktop with other computer, type each of these commands in order:

   sudo apt-get install x11vnc
   mkdir ~/.vnc && x11vnc -storepasswd YOUR_PASSWORD ~/.vnc/x11vnc.pass
   echo "/usr/bin/x11vnc -rfbauth ~/.vnc/x11vnc.pass -o ~/.vnc/x11vnc.log -loopbg -display :0" > ~/.kde/Autostart/x11vnc.sh
   chmod +x ~/.kde/Autostart/x11vnc.sh

You can test the server by running the shell script (just type ~/.kde/Autostart/x11vnc.sh) and after restarting KDE, the script should start the VNC server automatically. For customization of x11vnc server, edit the commands in the x11vnc.sh file enter after viewing "man:/x11vnc" in konqueror, where a description of parameters for x11vn is given.

Windows Compatibility

Mounting NTFS Partitions(with read/write privilege)

Install NTFS-3G:

sudo apt-get install ntfs-3g

Edit fstab:

sudo vi /etc/fstab

When kubuntu installation finished, kubuntu mounted all ntfs partisions automatically with ntfsprogs. Change(maybe slightly different in your machine):

UUID=8466268666267956 /media/sda1     ntfs    defaults,gid=46 0       1


UUID=8466268666267956 /media/sda1     ntfs-3g    defaults,nls=utf8,locale=zh_CN.UTF-8,umask=000,gid=46 0       1

In my case, I have a Chinese language windows installed on my first partition. set the locale parameter so that my Chinese documents can display correctly. set umask=0 let me write the partition without sudo.

Mounting FAT32 Partitions

Tips & Tricks

Restore Konqueror as Default File Manager

Run kcontrol (e.g. with K-menu -> Run command)

Open KDE components -> File Associations -> inode

Choose directory. In the right part of the window, change the application preference order so that Konqueror would be the first app in the list.

Do the same with system_directory.

Create a symlink from a file to another location

A symbolic link (also known as a symlink) is a method in Linux of referring to a file (or directory) in one location from another location. Usage:

ln -s /path/to/source /path/to/destination

If /path/to/destination requires superuser rights, then use:

sudo ln -s /path/to/source /path/to/destination

This is similar to, but more powerful than, creating Shortcuts, with which former Windows users may be familiar.

Get a root prompt without assigning a root password

In other GNU/Linux distributions you can switch to a root user prompt with su. However, in Ubuntu no password is set for the root user, and sudo is used instead. You can still get a root prompt in Ubuntu by typing:

sudo su

You can also get a prompt for any other user on the computer by typing:

sudo su <username>

Mount and Unmount a device

To mount a device:

mount /dev/hda

replace /dev/hda with the location of the device.

To unmount a device:

umount /dev/hda

replace /dev/hda with the location of the device.

Assign a root password

To be able to log in as root directly, you must assign a root password. This can be done with:

sudo passwd root

Afterwards, you can use


to get a root prompt.

Autostart a program at bootup

Any program (or script) can be made to Autostart at bootup by creating a symbolic link to that program (or script) in the ~/.kde/Autostart folder.

For example, to start Firefox at bootup, create a symbolic link:

sudo ln -s /usr/bin/firefox ~/.kde/Autostart

Run a script from a menu item

It is possible to place a short script in a menu item / shortcut to answer an interactive query (such as a password query). Here is an example that is used to enter a password during an SSH negotiation. First, install the utility expect:

sudo apt-get install expect

The use a command in the Menu Item / Shortcut similar to:

expect -c 'spawn ssh -l sshuser -L 5900: remoteserver.remotedomain.org -p 22 ; expect assword ; send "sshpassword\n" ; interact'

In this example the password sshpassword is returned when the ssh program requires a password. Expect waits for some text to be displayed in the command-line terminal then returns text in return. The Menu Item must be "Run in terminal", therefore.

Remove Konqueror thumbnails temporary files

When browsing files locally Konqueror builds up thumbnails of images viewed. To remove those, put this in the Konsole (substituting "user" with your username):

cd /home/user/.thumbnails/normal
rm -rf *.png
cd /home/user/.thumbnails/large
rm -rf *.png

Screen snapshot

K menu -> Graphics -> Ksnapshot Screen Capture Program

Save any streaming Flash video

Most Flash videos download to the /tmp directory while you watch the video, creating a randomly-named video file there (such as Flashuh4G6s). When you close the webpage, this file in the /tmp directory will be erased. After the entire video has downloaded, but before you close the webpage, copy that file (such as Flashuh4G6s) to your home directory (where it will not be erased). Of course, for this to work, you must change your Flash (or Gnash) settings to allow an unlimited buffer. While watching your Flash video, right click to bring up the Flash -> Settings window. Set the Buffer to "Unlimited."

Once you have copied the file, rename it appropriately with the .flv added to the filename. You can then watch it using VLC or Mplayer.

Here is another method that involves making a symbolic link.

If you get a permissions error when launching Amarok, try the following:

sudo chown -R user /home/user 

("user" replaced with the actual username)

Codeweavers Crossover Office 6

Crossover Office 6 NOT creating any menus in Gutsy

This is a bug within Crossover Office and NOT Kubuntu Gutsy. Here is an easy fix (from start):

Install Crossover Office 6 (presuming you have the .deb file):

cd /browse/to/the/directory

("/browse/to/the/directory" replaced with the actual directory holding the .deb file)

sudo dpkg -i crossover-pro_6.0.0-1_i386.deb

("crossover-pro_6.0.0-1_i386.deb" replaced with the actual name for the .deb file)

You will get the following error after installation (you can just ignore it):

fileparse(): need a valid pathname at /opt/cxoffice/lib/perl/CXMenuXDG.pm line 254

Now edit the following file:

sudo nano /opt/cxoffice/lib/perl/CXMenuXDG.pm

Near line 254 replace the following:

my $dir=dirname($self->{filename});

With this:

my $dir=dirname($self->{menu});

Press CTRL + X and then Y to exit.

Now run the following command:

/opt/cxoffice/bin/cxmenu --crossover --install

(NOTE: You must not do this as "sudo" user).

Now to finish off do:

killall kicker

You can check that the menus are now created!

Katapult Troubleshooting

Katapult Configurations

Katapult is pre-installed in Kubuntu and gives you easy access to all the programs on your computer. To use it press ALT+SPACE, then enter the first few letters of the program you want to access.

To enable the Calculator in Katapult, press ALT+SPACE followed by CTRL+C > Configure Katapult > Catalogues. Here you can move the Calculator option from the left to the right, and click OK. From now you can access Calculator via ALT+SPACE followed by the number you wish to calculate.

K3B Troubleshooting

Cdrecord has no permission to open the device error

If you receive the "cdrecord has no permission to open the device" error while burning using K3B, open a terminal and type:

sudo chmod 777 /dev/scd0

- replacing "/dev/scd0" with your own device.


Linux is largely a community of volunteers and as such represents one of the largest altruistic efforts on earth. This includes companies who decide to contribute their own software into the public domain for free use. The continued success of sharing depends on licenses that keep software free and usable for anyone who wants to use it. However, there must be a method for Linux users and developers to make money, as well. Licensing helps protect each of these efforts. See the Wikipedia Free Software Licensing article and the GNU operating system licensing page for more complete information.

GPL license

The GPLv3 license intends that the software module or package is free to use in any environment, and furthermore, any software that relies on that GPLv3-licensed module must in turn also be completely free. Commercial and proprietary software packages can't use or incorporate GPLv3-licensed modules.

LGPL license

The Lesser GPL license intends that the software module or package is free to use in any environment, including in commercial and proprietary software packages. This allows companies to develop proprietary packages which includes LGPL-licensed modules, from which they can make a profit. The disadvantage is that their products (which benefit from the LGPL-licensed modules) are not required to be in the public domain in turn. (Many companies often later donate their entire package into the public domain, however, after they no longer make a profit from them.)

Proprietary licenses

There is a vast array of proprietary licenses, all different. You never know what your limitations for software are unless you read every word. Most are attempts by lawyers to have an opportunity to create a lawsuit in the future. Some may be called "free" licenses but have many limitations which you will not be aware of until you are in the middle of a lawsuit. No license outside of the GPLv3 licenses is recommended. Be careful when committing your organization to a mission-critical software package with a proprietary license. Also see this outstanding article on the Open Source Enterprise Trap.
