Martin,

I'm using the same version of X as Paul. To configure X I used a
mandriva live cd, copy the xorg.conf (because compiz was running fine
without any manual settings) and checked the loaded modules (I can give
you the module list if you're interesting). once this step done I copied
the conf file and restart gdm. Once logged into Gnome I tried to launch
compiz with "compiz-manager", unfortunately I didn't get any nice
effects (still don't know why). Then I killed compiz and started beryl
with "beryl-manager" and it worked nice. I know beryl is considered as
piece of crap and just hacks of compiz but only this one works.

I just don't know how to manage to move the cube with the mouse fine but
when I switch desktops it turns anyway.

I guess you have not to forget this section if you're using AIGLX :
Section "ServerLayout"
    Option "AIGLX" "true"
EndSection

I don't know what means this message but it seems like I don't have to
care about it : "libGL warning: 3D driver claims to not support visual 0x4b"
