I use Ubuntu since 2005 and recently also see rendering problems with my ATI X600 and others like X1200. But I never saw problems like your screenshots. I recommend you to create a new Ubuntu bug report (by executing "ubuntu-bug" in a terminal) or directly upstream on https://bugs.freedesktop.org where the graphics system is hosted.
Meanwhile you could try to: - boot with the kernel option "nomodeset" (press F6 on boot menu screen) - login with "Ubuntu classic (without effects)", or uninstall Compiz effects completely by executing "sudo apt-get remove compiz-core" in a terminal - downgrade to the latest Long Term Support release "Ubuntu 10.04 LTS" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/556782 Title: [rs690m] Graphics corruption with ati x1200 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/556782/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
