Just to confirm this bug on a customers Radeon 6450 machine with xubuntu 12.10 64bit.
3.5.0-21 - works properly 3.5.0-22 - bug happens randomly, sometimes not on 3.5.0-23 - bug happens all the time i tried 3.5.0-24 from quintal-proposed, bug happens all the time Disabling graphical grub by uncommenting /etc/default/grub GRUB_TERMINAL=console helped to workaround this issue in all affected kernels... AFAIK same as Przemysław's solution but should survive grub menu updates. Description of screen issues: I tried two available monitors, both LCD connected via VGA. Old 15" one shows image but moved about 75% to the right and extra picture is cut and displayed on the left. Some minor corruption occurs on the bottom. Newer 22" monitor does not show picture at all, just kinda... general color? Color of the first pixel? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1113781 Title: linux-image-3.5.0-22-generic and linux-image-3.5.0-23-generic are causing video display problems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1113781/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
