I notice that your monitor is connected via DisplayPort. There were some DisplayPort fixes in the upstream 3.14 kernel. A PPA of the 3.14.12 kernel is available at http://kernel.ubuntu.com/~kernel- ppa/mainline/ and instructions on how to install and uninstall it are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds
Can you please try this updated kernel and report the results here? ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1328026 Title: Screen corruption on rotate (Unity, radeon) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1328026/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
