I think that I have found that this issue is related to using a 2nd monitor.
Sequence 1 (I am not sure if this causes the display corruption), but its related to sequence 2: 1. 2nd monitor is not detected when plugged into hdmi (its own issue) 2. I click the "gear" in the top right, then "Displays" 3. The monitors "flicker" but the 2nd one is detected. Unity almost always crashes here (another issue) 4. Both displays work properly Sequence 2 (I think this causes the corruption) 1. 2nd monitor is already working, either from sequence 1, or because I booted with it connected. 2. I unplug the hdmi monitor. 3. I click the "gear" in the top right, then "Displays" 4. The monitors "flicker" and the hdmi monitor is de-registered 5. If I suspend the system here, when I resume I will almost certainly (maybe 100% certainly, just not convinced yet) have to fix the display corruption bug reported here. The system will never resume without the corruption issue at this point until I reboot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/881779 Title: Dell Studio 15 Display Corruption After Resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/881779/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
