I did some more testing today. It seems one simple way to reproduce this is to just move the mouse pointer around on the login screen. At one point this even lead to a kernel panic (see attachement).
Again, setting the power profile to something other than "default" seems to get rid of the problem. ** Attachment added: "kernel_panic.jpg" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1313459/+attachment/4099841/+files/kernel_panic.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1313459 Title: Screen corruption with Radeon 6670 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1313459/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
