Description José Jorge 2015-08-23 09:17:00 UTC
It looks like the driver needs a xdamage event to redraw the screen after suspend : if I have two windows opened, then suspend/resume, I get a black screen with only the mouse cursor. Than a simple Alt+Tab draws the screen.

How to debug the X event that is waited by the driver?

Please attach /var/log/Xorg.0.log and the output of dmesg captured after suspend/resume.

After second suspend, all is ok after Alt-Tab the bring back a reduced window.

So did I. I noticed that with Firefox and Konsole opened, the screen is ok after resmued. Reducing both has triggered the bug on second suspend.
