Red Hat Bugzilla – Bug 1288791
No displays activate after returning from suspend
Last modified: 2016-01-06 21:41:22 EST
Description of problem: When resuming from suspend no monitors turn on.
MATE 1.12.0. I'm not sure what program specifically controls the displays.
Steps to Reproduce:
1. Disable internal display and activate external display
2. Suspend system via menu option
3. Resume system using power button
Neither display turns on. Undocking the laptop(without suspend) triggers the internal display to activate and the lock screen is there.
System restores previous state with external display only.
Latitude laptop (Intel GM45/GE45/GS45 Integrated Graphics) with external monitor connected to docking station.
If I suspend by closing the lid the same effect occurs. Again, undocking and re-docking fixes it.
