Hello,

at the beginning I installed cairo-dock. It asked me to turn on opengl so I agreed. Unfortunately Trisquel became more unstable (it sometimes freezez). I removed cairo-dock, but the opengl didn't turn off. I tried to change it with:
metacity --replace
and installing "compiz-fusion" then selecting the metacity window manager but without any result. Any ideas?
Thanks.

Because I'm afraid that all graphic environment will break down.
I think that I should turn it off before removing it.

You should not worry that much. :-)

If you really want to avoid any potential problem while removing Compiz, you can follow those steps:

  1. Ctrl+Alt+F1 (open a real terminal)
  2. Log in
  3. sudo service gdm stop (stops anything graphical that is running)
  4. sudo apt-get remove compiz (removes Compiz)
  5. sudo service gdm start (start the graphical login manager)

Well, I did it but it didn't work. Compiz was removed, but for example shadow near every window didn't disappear.
I've reinstalled whole system and now it's ok.

But I'm a little afraid of installing cairo-dock :)
Thanks for your help.

Those are the window manager's effects. Metacity has a setting to do its
own compositing and one of the things it does is add a shadow around
windows.

In case it happens again, here are the steps to remove Metacity
compositing/effects:
1. Install "gconf-editor" if it is not there
2. Run "gconf-editor"
3a. Set /apps/metacity/general/compositing_manager to False ("Determines
whether Metacity is a compositing manager.")
3b. Or, just set /apps/metacity/general/compositor_effects to False
("Determines if compositor-related effects are enabled or not. More
specifically, it disables the shadows below windows, the support for
windows opacity and the windows previews in the alt+tab window switcher.
It does not have any effect if compositing_manager is disabled.")
