journal telling the problem

On my laptop Thinkpad T510 the screen freeze occasionally.
I can work for several hours, including suspend-resume, then suddenly, I think usually when I change between open applications, the desktop visually freezes - only mouse pointer visually works.

ctrl-alt-F4 etc do not visually switch screen.

I bring it down cleanly (minus lost work in open app) using REISUB.

Relevant part of journal attached.

It was running desktop kernel but I have now switched to linus kernel to see if it seem to work better or worse.

System info as I write this:

Comment 1 Morgan Leijström 2024-05-15 22:49:18 CEST
Happened again, now with linus 6.6.28.
This time i was briefly away from the laptop and when i returned i clicked an open application window and the screen went totally black except for mouse arrow which was moveable.

Used REISUB to bring it down.

In log i see same problem as before, first relevant lines:
