A few days ago, I updated the kernel to
3.2.0-29-generic-pae. Since then, all compiz effects have disappeared (all such as wobbly windows, windows switcher, workspace changing effects...).
unity --reset or
compiz --replace commands don't help as all the windows' edges/buttons vanish, the desktop background becomes black. After rebooting, I am back to a working interface, but without compiz effect.
I have tried the following solutions which have no effect on my desktop:
- Changed some settings in Compiz - now Ubuntu freezes on startup
- How do I reset my Unity configuration?
Do you have any ideas on how I can fix this problem ? Help will be appreciated !
