Problems
Our F.A.Q
  • F.A.Q one question one answer



Composite
A black background ?
  • ATI cards : try without OpenGL (cairo-dock -c) => Drivers aren't correct !
  • Intel cards : some of them work with OpenGL (see the follow section) or try without OpenGL (cairo-dock -c) => Some drivers aren't correct !
  • KDE4 : launch systemsettings and do that : Look & Feel --> Desktop --> Desktop Effects --> Enable Desktop Effects. You can also have a look to this post: here.
  • Gnome without Compiz (just with Metacity) : apply this command from a terminal :
    gconftool-2 --type bool --set /apps/metacity/general/compositing_manager true
  • More details : Composite Manager



OpenGL
A black background? A crash with it?
  • Intel cards: Cairo-Dock with OpenGL support seems to be "fully" supported, more informations here
  • Nvidia cards : It has worked for a long time! More informations here
  • ATI cards : Cairo-Dock with OpenGL support seems to be "fully" supported, more informations here

  • But you can use Cairo-Dock with a fake transparency in the System menu in the config panel of Cairo-Dock (or by using it with a black wallpaper )



(S)MPlayer
If you have any problem with (S)MPlayer :
    • Try to put the video output to gl2 (in the settings of SMPlayer)
    • Or use this command to launch (S)MPlayer:
      export XLIB_SKIP_ARGB_VISUALS=1 && smplayer &



Others apps based on Qt4 like VirtualBox, Skype, VLC
(for VLC, there is a bug only if the option 'Integrate video in interface' is enabled)
It's the same problem that (S)MPlayer.
    • Create a file with the extention ".sh" (launch_virtualbox.sh for example)
    • Add these two lines :
      export XLIB_SKIP_ARGB_VISUALS=1
      virtualbox
    • Change the right execution (Right clic on the file / Properties / Permissions / Execution => or directly :
      chmod +x launch_virtualbox.sh
    • Use this file to execute this app.



Problem with installation / update ?
If you have something like this:
  • trying to overwrite `/usr/share/cairo-dock/default-indicator.png', which is also in package cairo-dock-data
    dpkg-deb: subprocess paste killed by signal (Broken pipe)
  • E: /var/cache/apt/archives/cairo-dock_2.0.0_all.deb: tentative de remplacement de « /usr/share/cairo-dock/icon-mouse.png », qui appartient aussi au paquet cairo-dock-data.


You need to do the following :
sudo apt-get remove cairo-dock* --purge
sudo apt-get install cairo-dock cairo-dock-plug-ins




Problem to change/save your configuration ?
It could be a permission problem:
chmod u+rwx -R ~/.config/cairo-dock/




Problem with a gauge ?
If you have an output like this:
xterm -e ' wget "http://themes.glx-dock.org/gauges/turbo-night-fuel/turbo-night-fuel.tar.gz" -O "/tmp/cairo-dock-net-file.AfLFEO" -t 2 -T 5'

Just swap gauges in your enabled plugins with it s equivalent starting with capital letter (eg. turbo-night-fuel => Turbo-night-fuel).



Problem with wifi applet ?

It's a problem of access right to iwconfig command.
As root (root = sudo for Ubuntu for example), do this commands in a terminal:
chmod u+x /sbin/iwconfig # or "chmod 755 /sbin/iwconfig" if it still doesn't work
ln -s /sbin/iwconfig /usr/bin/iwconfig




Problem when Cairo-Dock is launched automatically ?

If you have some bugs when Cairo-Dock is launched automatically at startup and not when it's launched manually : Try to launch it with a delay.

In your session manager (help here), use this command :
sh -c "sleep 15 && cairo-dock -o"

Change any parameters according to your configuration (here we have 15 seconds and Cairo-Dock with OpenGL)



A message at startup

Read it or go here for more help !



No theme available?

Do you use a proxy to be connected to Internet? If yes, you have to configure Wget.
It's easy, edit (or create) this file '~/.wgetrc', e.g. with gedit :
gedit ~/.wgetrc
Past these informations and modify the first line with the complete URL of your proxy :
http_proxy = http://MY_PROXY:3128/
use_proxy = on
wait = 15
If you have to use an username and a password, modify the first line like that:
http://username:password@my_proxy:3128/




No icon on menu, GMenu, etc. on Gnome 2.28?
Two possible methods to fix this problem :
From a terminal
Simply apply this command :
gconftool-2 --type bool --set /desktop/gnome/interface/menus_have_icons true && gconftool-2 --type bool --set /desktop/gnome/interface/buttons_have_icons true


With a GUI
Open 'gconf-editor', go Desktop / Gnome / Interface and enable "menus have icons" and also "buttons have icons"
