I am hoping that someone on this list is an ATI expert. I just installed Ibex, but I have been having the problem described below on prior versions of Ubuntu. <br><br>I am not able to use Compiz Fusion desktop effects when I enable the proprietary ATI driver along with dual monitors in Big Desktop mode. I understand that this is a limitation of the video card. When I run compiz from a shell a message is displayed that my resolution is 2560x1024, which is lower then the 2048xXXXX maximum for 3d graphics. Ideally, I'd like each monitor to treated seperately. I don't want a combined desktop, especially since when I maximize programs they cover up both screens. <br>
<br>I have Googled the issue and know that this is a common experience for ATI cards. Is there any hope for me outside of buying a new laptop with a Nvidia graphics card? Isn't there supposed to be a dual head mode used for the propriatary driver? <br>
