I had the same problem (00:02.0 VGA compatible controller: Intel
Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics
Controller (rev 03)) on a macbook 2,1 and solved it removing the blur
effect:
System-settings --> Desktop Effects --> All effects
This solved my problem.
If it doesn't work I'd try to disable all desktop effect, see if the
problem still there, if it doesn't then try to re enable those that
you need one by one, to identify the buggy one.
Hope this helps.
