I unmarked this bug as duplicate of 541501 as there is a patch for 541501 - but no update that was released last time seemed to help me with my problem of flickering and shivering on external monitor.
but as i installed the latest kernel from https://wiki.ubuntu.com/KernelTeam/MainlineBuilds?action=show&redirect=KernelMainlineBuilds the problem doesn't appear again. probably the bug is not in the *-ati package but in the kernel? ** This bug is no longer a duplicate of bug 541501 [RV515] [LENOVO T60] external screen display shows "shivering", horizontal refresh offset -- flickering on external screen https://bugs.launchpad.net/bugs/559482 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
