Notas generales

  1. Esto es una guía no oficial para Ubuntu 6.06 (Dapper Drake). No está asociado con Ubuntu y Canonical Ltd.
  2. La guía fue probada en una instalación completa del Ubuntu 6.06 x86 Install CD (Dapper Drake)
  3. Si usted ve una caja azul, esto significa que usted tiene que ejecutar los comandos en el modo terminal (Applications -> System Tools -> Terminal) o usar el contenido en la caja de acuerdo a otras instrucciones mencionadas.
  4. Para reducir errores de escritura, copie y pegue los comandos en el modo terminal (seleccione los comandos y oprima el botón derecho de su mouse -> seleccione "Copy" o "Paste". Además, puede usar Ctrl+C para copiar texto seleccionado y Shift+Insert para pegarlo).
  5. "sudo" significa "superuser do" o superusuario haga. "sudo" le pedirá su contraseña ("Password:"). Por favor entre su contraseña cuando se lo pida.
  6. Si desea más información sobre cualquier comando, simplemente mire el "man page" o el manual usando el comando "man <comando>". Por ejemplo, "man sudo" le enseñará el manual para el comando "sudo".
  7. Si está cansado de escribir "apt-get" todo el tiempo, lea #How to apt-get the easy way (Synaptic)
  8. "apt-get" y "wget" requieren conección al Internet para instalar, actualizar, o descargar programas.
  9. Para descargar un archivo, oprima el botón derecho del mouse sobre el enlaze -> seleccione "Save Link As..." -> esté seguro que el nombre del archivo y su extensión (i.e. *.txt, *.tar, *.bin) están correctos
  10. Si desea ayudar traduciendo Ubuntu a su lenguaje nativo or a ayudar Ubuntu en cualquier manera, visite https://launchpad.net/
  11. Que el espíritu "humanidad a otros" esté con usted siempre...
Si está usando Kubuntu, necesita instalar Gedit 
sudo apt-get install gedit
O remplaze 'gedit' con 'kwrite', por ejemplo, en vez de escribir 
sudo gedit /etc/apt/soureces.list
Escriba 
sudo kwrite /etc/apt/sources.list
Si está usando la versión de 64-bit, remplaze "i386" con "amd64"

sudo gedit /etc/gdm/gdm.conf-custom
  • Replace everything with the following lines 
# GDM Configuration Customization file.
#
# This file is the appropriate place for specifying your customizations to the
# GDM configuration.   If you run gdmsetup, it will automatically edit this
# file for you and will cause the daemon and any running GDM GUI programs to
# automatically update with the new configuration.  Not all configuration
# options are supported by gdmsetup, so to modify some values it may be
# necessary to modify this file directly by hand.
# 
# To hand-edit this file, simply add or modify the key=value combination in
# the appropriate section in the template below.  Refer to the comments in the
# gdm.conf file for information about each option.  Also refer to the reference
# documentation.
# 
# If you hand edit a GDM configuration file, you should run the following
# command to get the GDM daemon to notice the change.  Any running GDM GUI
# programs will also be notified to update with the new configuration.
#
# gdmflexiserver --command="UPDATE_CONFIG <configuration key>"
#
# For example, the "Enable" key in the "[debug]" section would be specified by
# "debug/Enable".
#
# You can also run gdm-restart or gdm-safe-restart to cause GDM to restart and
# re-read the new configuration settings.  You can also restart GDM by sending
# a HUP or USR1 signal to the daemon.  HUP behaves like gdm-restart and causes
# any user session started by GDM to exit immediately while USR1 behaves like
# gdm-safe-restart and will wait until all users log out before restarting GDM.
# 
# For full reference documentation see the gnome help browser under
# GNOME|System category.  You can also find the docs in HTML form on
# http://www.gnome.org/projects/gdm/
# 
# NOTE: Lines that begin with "#" are considered comments.

  • To run compiz for this session 
thefuture
  • To have compiz load on startup
    • System -> Preferences -> Sessions
    • Startup Programs -> Add 
/usr/bin/thefuture
  • Troubleshooting
    • If Xgl/Compiz doesn't seem to work, or you get errors, simply restart your machine after adding "thefuture" to Startup programs
    • If moving windows slows down the system, run gconf-editor from the terminal. Find apps/compiz/general/screen0/options. Disable detect_refresh_rate and set refresh rate to 60. Everything should work fine now...
    • If you are using a non default keyboard layout (other language), you might have to change it back to what you need if the keyboard acts funny at System/Settings/Keyboard.
    • You can also set the Super-key to the windows button here.
  • Tips
    • Switch windows = Alt + Tab
    • Arrange and View All Windows = F12 turns on or off; clicking a window will zoom it to the front
    • Switch desktops on cube = Ctrl + Alt + Left/Right Arrow
    • Switch desktops on cube - with active window following = Ctrl + Shift + Alt + Left/Right Arrow

How to install a Wacom tablet

For a detailed guide with screenshots about how to configure the "Extended input devices" in your graphic applications, please follow the official Dapper guide at https://wiki.ubuntu.com//Wacom

With the version of the Linux Wacom driver (0.7.2) in Ubuntu 6.06 Dapper Drake, if you unplug you tablet, it won't function when you plug it back in and you will have to restart X. For this reason, it is best to leave the tablet plugged in. This limitation will be removed when the 0.7.4 version of the driver is included in Ubuntu.

  • 1. Using Synaptic package manager1, check if the packages xserver-xorg-input-wacom and wacom-tools are already installed - if not, install them. If you prefer using the command line, you can also execute : 
     sudo apt-get install xserver-xorg-input-wacom wacom-tools
  • 2. Save a copy of your /etc/X11/xorg.conf : 
      sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
  • then edit it with the command line : 
      sudo gedit /etc/X11/xorg.conf
  • and change all /dev/wacom occurences into /dev/input/wacom (created by wacom-tools udev scripts), then save the file.
  • You should be ready to go after you have restarted X. Remember to configure the "Extended input devices" in your graphic applications (Gimp, Inkscape), however you can already check if it's working by moving your stylus on the tablet : the mouse cursor should go through the whole screen.

How to type extended characters

  • Add the keyboard layout US English International (with dead keys)
  • Make US English International (with dead keys) the default keyboard layout.

The key marked ['"] is now a dead key. When you press it, nothing happens. However if you press a consonant immediately afterwards, the consonant appears with an accent.

  • ' + a = á
  • ' + e = é
  • and so on for i-í, o-ó, y-ý, c-ć, z-ź, n-ń, l-ĺ, u-ú, r-ŕ
  • " + a = ä
  • " + e = ë
  • and so on for y-ÿ, u-ü, i-ï, o-ö

Similarly, ` and a consonant generates à, è, ù, ì, ò. Similarly, ~ and a consonant generates ã, ũ, ĩ, õ, ñ.

To type ' and ", press RightAlt+' and RightAlt+" respectively. To type ' and ", you may also press '+<space> and "+<space> respectively.

There are more characters available by keeping RightAlt pressed and typing a character. Therefore,

  • RightAlt+q = ä
  • RightAlt+w = å
  • RightAlt+e = é
  • RightAlt+r = ®
  • RightAlt+t = þ
  • RightAlt+y = ü
  • RightAlt+u = ú
  • RightAlt+i = í
  • RightAlt+o = ó
  • RightAlt+p = ö
  • RightAlt+[ and ] for « and » respectively.
  • RightAlt+a = á
  • RightAlt+s = ß
  • RightAlt+d = ð
  • RightAlt+l = ø
  • RightAlt+; = ¶
  • RightAlt+: = °
  • RightAlt+z = æ
  • RightAlt+c = ©
  • RightAlt+n = ñ
  • RightAlt+m = µ
  • RightAlt+, = ç
  • RightAlt+/ = ¿
  • RightAlt+1 = ¡
  • RightAlt+2 = ²
  • RightAlt+3 = ³
  • RightAlt+4 = ¤
  • RightAlt+5 = €
  • RightAlt+6 = ¼
  • RightAlt+7 = ½
  • RightAlt+8 = ¾
  • RightAlt+9 = ‘
  • RightAlt+0 = ’
  • RightAlt+- = ¥
  • RightAlt+= = ×
  • RightAlt+! = ¹
  • RightAlt+@, then o = ő (and Ő).
  • RightAlt+#, then a = ā (and Ā). Similarly for ēĒ, ūŪ, īĪ, ōŌ.
  • RightAlt+$ = £
  • RightAlt+% =
  • RightAlt+^ =
  • RightAlt+& =
  • RightAlt+*, then a = ą (and Ą). Similarly for ęĘ, įĮ.
  • RightAlt+(, then a = ă (and Ă)
  • RightAlt+(, then g = ğ (and Ğ)
  • RightAlt+), then a = å (and Å)
  • RightAlt+_ =
  • RightAlt++ = ÷

How to set the Compose key to type special characters

  • Click System, Preferences, Keyboard.
  • Under Layout Options, expand on Compose key position.
  • Choose Right-Win key is compose, click Close.

Now you can type extended characters using the RightWin key (next to AltGr), according to this keyboard settings file. Specifically, the lines that start with GDK_Multi_key are those that we can use here. The Compose key is actually GDK_Multi_key.

Some examples,

  • RightWin + C + = produces €
  • RightWin + = + C produces €
  • RightWin + C + O produces ©
  • RightWin + O + C produces ©
  • RightWin + a + ' produces á
  • RightWin + a + " produces ä
  • RightWin + a + ` produces à
  • RightWin + a + ~ produces ã
  • RightWin + a + * produces å
  • RightWin + a + ^ produces â
  • RightWin + a + > produces â
  • RightWin + a + , produces ą
  • RightWin + e + - produces ē
  • RightWin + S + 1 produces ¹
  • RightWin + S + 2 produces ²
  • RightWin + S + 3 produces ³

How to limit the user accounts that can connect through ssh remotely

e.g. If you enable the SSH server, then any user with a valid account can connect remotely
This can lead to security risks, as there exist remote password cracking tools that
try common username/password pairs.
  • Keep a backup of the ssh server configuration file with

sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.ORIGINAL

  • Edit the configuration file

sudo gedit /etc/ssh/sshd_config

  • Change the parameter PermitRootLogin from yes to no. The superuser must not be able to connect directly from remote.
  • Add the parameter AllowUsers and specify the usernames (space separated) that can connect remotely.
  • You can also use DenyUsers for fine-grained selection of users.
  • If you enable the openssh server and you have no intention for now to enable remote connections, you may add AllowUsers nosuchuserhere to disable anyone connecting.
