Got the same problem with my Radeon HD 6620G. The -ati driver is very slow for Unity.
My temporary workaround: - Downgrade xserver-xorg-core to precise (1.11), and then - download Catalyst 12.8 from http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx and create build for quantal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1032672 Title: fglrx-updates broken dependency with xorg-video-abi-12 (Quantal) To manage notifications about this bug go to: https://bugs.launchpad.net/nvidia-drivers-ubuntu/+bug/1032672/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
