Can I change compizs shortcuts ?
Yes, use compiz settings manager. OLD : you can change shortcut using Gconf-Editor in Application > Systeme > Gconf. Next apps->compiz->plugins->{cube|zoom|wobbly…}->screen0->options. Or using Gset-Compiz Q : Xgl is launched but, screen is gray A : Try install devel packages. If you have an ATI graphic card, the problem may be it… another thing, You MUST install graphic drivers BEFORE installing Xgl’s packages.
