Description Papoteur 2018-09-01 07:14:36 UTC

I use a laptop with a second screen connected over HDMI. Both screens use 1920x1080 resolution.
I get sometimes weird situation where the second screen displays a normal screen (windows or lockscreen) but what it displays is friezed. However all seems to be active, I can for example slide window from the second screen to the first one.
Clicking with the mouse has expected behaviour, except that I do it blindly. It seems that I have a mask on the second screen.
This happens when I disconnect and reconnect the second screen with a suspended session period in between. There is other cases when this happens, but I'm not sure of the circumstances.
I didn't find any error reported in journal.
Which information can be found to help the debugging?
