Recurrents problems

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

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
  • XFCE with its Window Manager (XFWM): simply go to Applications / Parameters / Parameters Editor / XFWM4 module / General tab / Enable use_compositing (turn it to TRUE)
  • More details : Composite Manager

A black background? Invisible icons?
  • 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 and Kaffeine
If you have any problem with (S)MPlayer or Kaffeine:
    • Try to put the video output to gl2 (in the settings of SMPlayer)
    • Or use this command to launch (S)MPlayer (adapt for Kaffeine):
      export XLIB_SKIP_ARGB_VISUALS=1 && smplayer &
      env XLIB_SKIP_ARGB_VISUALS=1 smplayer &
      sh -c "env XLIB_SKIP_ARGB_VISUALS=1 smplayer"

Others apps based on Qt4 like VirtualBox, Skype, VLC
(for VLC, there was a bug only if the option 'Integrate video in interface' is enabled and vlc devs have added this workaround into the application)
  • It's the same problem that (S)MPlayer, so you can use this command in order to launch your application, e.g.:
    export XLIB_SKIP_ARGB_VISUALS=1 && skype
  • But you can also make a little script:
    • Create a file with the extention ".sh" (launch_virtualbox.sh for example)
    • Add these two lines :
    • 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.
  • Or edit the launcher and use a command like this one:
    sh -c "env XLIB_SKIP_ARGB_VISUALS=1 kaffeine"

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 / Two Docks at startup

Read it or go here for more help !
And if you have two docks at startup: Execute cairo-dock at startup

No theme available?
Do you use a proxy to be connected to Internet? If yes, you have to configure Curl.
It's easy, edit (or create) this file '~/.curlrc', e.g. with gedit :
gedit ~/.curlrc
Past these informations and modify the last line with the complete URL of your proxy :
#We want a 30 minute timeout:
-m 1800
#. .. and we use a proxy for all accesses:
proxy = proxy.our.domain.com:8080
If you have to use an username and a password, add this line :
user = user:passwd

Old release
After a problem with our registrar (vivadomaine) we have to change our domain name. So if you use an older version that the 2.1.3, please update it !
Something else?
Maybe your connexion is too slow (or you're too far from our server), open the config panel of Cairo-Dock (right click on the dock / Cairo-Dock / Settings), click on the Advanced Mode (on the bottom-left) / System module / Connexion to the server / and increase all numbers.

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"

Themes Manager only displays the _default_ theme?
If you have the version 2.1.3 (newer or equal), there is maybe a little problem with IPv6 (due to an old DNS server we guess). You can try this workaround:
  • Edit this file ~/.curlrc with a text editor, e.g. with gedit
    gedit ~/.curlrc
  • Add this line

If you still have the bug, please report this bug to our forum!
