I also have an ATI card (FireGL V5250), and could get compiz/beryl to work only with the fglrx driver (unfortunatelly) over XGL. I installed jdong's patch more than a week ago. I had problems with Beryl now and then (famous white screen, white borders, and content of windows not refreshed bugs). But since I switched to compiz, its been rock solid. I'm no fglrx guru, but by now I spent tens of hours configuring xorg.conf options, installing SVN snapshots of beryl, switching between Xorg7.1.1 and Xorg7.2, etc. The configuration that is the most stable on my system (Thinkpad T60p, Feisty) is: xserver-xorg 1:7.2-0ubuntu2 xserver-xgl 7.2.0.git.20070224-0ubuntu2 (jdong's) compiz 1:0.3.6-1ubuntu7
the xorg.conf file is attached. I hope this can help you in making your decision. ** Attachment added: "xorg.conf file" http://librarian.launchpad.net/6646374/xorg.conf -- New git snapshot required for xorg 7.2/feisty https://launchpad.net/bugs/87687 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
