Every time I change effects in Compiz my top bar gets screwed and I have to log out and log in again. Is it normal?
Can't install Simple Compiz Config Manager. Is it normal?
I'm sorry you are encountering this problem (even if you didn't state exactly what the problem is ("get's screwed" does say much :)). (I assume you are running unity and 11.04 from what you describe).
In the future, all you need to do after changing you compiz settings, is:
This will reload compiz and unity and should fix your problem as well. Hopefully the problem will be fixed in some soon_to_come bug fix updates.
stuff means keyboard_key_to_press
It happend for me to. And it also happened with ubuntu-tweak. Top panel becomes filled with a lot of colors or transparent... After restart and not using thoes 2 application it's ok.
