Some more details from Xorg.0.log when this happens i am seeing this:
[192017.116] (WW) RADEON(0): flip queue failed: Device or resource busy [192017.116] (WW) RADEON(0): Page flip failed: Device or resource busy [192018.675] (WW) RADEON(0): flip queue failed: Device or resource busy [192018.675] (WW) RADEON(0): Page flip failed: Device or resource busy [192018.703] (WW) RADEON(0): flip queue failed: Device or resource busy [192018.703] (WW) RADEON(0): Page flip failed: Device or resource busy I am now running with this options: Option "EnablePageFlip" "off" Option "ColorTiling" "off" to see if this helps. But gnome-shell is more than "slow" and nearly unusable with pageflipping off. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/932003 Title: gnome-shell freeze - must reboot to recover, lightdm+dbus restart does not help To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/932003/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
