Hi,
I activated compiz in openSUSE 11.
But when I click to maximizes a windows it maximizes another windows, I go to the corners to resize a windows it resize another windows, I’m start thinking my laptop is playing with me 
But after I installed Emerald and executed: ‘emerald --replace’ , and the problem gone, so it seems a problem with ‘kde4-window-decorator’.
Now I don’t know how to compiz start automatically Emerald in place of ‘kde4-window-decorator’, for now I have to execute emerald manually every time.
My hardware is a:
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)
in a Thinkpad T61.
My part of xorg.conf:
