It appears to me that I might have found a configuration that works quite good for me: I'm now running the most current mainline kernel (linux-image-2.6.37-999-generic_2.6.37-999.201012151130_i386.deb). Desktop effects were still disabled by default, but I could enable them by turning of the functionality checks for desktop effects (K Menu -> System Settings -> Desktop Effects -> Advanced -> Disable functionality checks).
So far, the performance is good (even smooth fullscreen playback of YouTube flash videos), and the system is running stable. Before, I had also tried out a natty live cd (desktop effects seemed to be enabled there), and the mainline kernel v2.6.32.27.12-lucid (linux- image-2.6.32-0206322712-generic_2.6.32-0206322712.201012110909_i386.deb, desktop effects enabled even with functionality checks enabled). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/687489 Title: Random freezes and no desktop effects after upgrading to maverick (radeon driver, ATI Mobility Radeon 9600) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
