Blank screen after Standby

[wadesmart]

I recently had to switch from X11 to Wayland for an app and experienced this very thing and more. Screen would freeze, mouse could move but you cant click on anything, sometimes the mouse wouldnt move, watching videos in the browser - the video sound kept playing but the desktop was frozen for several minutes at a time. I couldnt max any app as it would go up to the right and off the screen - but not every time. I switched back to x11 - instantly fixed everything. Now I see that KDE is dropping x11 support so Im back trying to figure this out.

I did spend some time looking at the logs but nothing stood out and posting in other forums (log results) got no response.

OK, time to start reviewing logs to see what might be causing it.

Same here. Blank screen and frozen mouse pointer after standby. Not always but very very often.

Which logs would be interesting?

The computer is frozen and only the frozen mouse pointer and a blank screen is visible

Is the computer frozen or just the desktop? Try CTRL-ALT-F3 and see if terminal mode loads.If it does, log in and type:

killall plasmashell && kstart5 plasmashell

This should restart the desktop. Then put it in standby again. Wait a minute or so, then wake it up. If it's frozen again, CRTL-ALT-F3 again and see if any messages have been added to the terminal. If not, enter:

sudo dmesg

And see what messages were generated from the time you tried to wake it up.

Post any messages.
