Screen/display jumping/flickering and laptop briefly freezing

There seems to be a post length limit, so this is part 1/n…

I’ve install Debian 11 from scratch, and I’ve been configuring, and everything has been fine - until about ten minutes ago.

At that time, I did two things.

First, I viewed a PNG, having installed wine. Wine is bloody idiotic, and makes various apps in wine (such as IE) the default apps for a bunch of file types. As a result, the image opened up in Internet Explorer.

Second, immediately after I sorted that out, I installed arc-theme (which requires a GTK2 engine) and switched to arc-dark…

Part 2/n…

…and now for whatever reason the laptop display is now “jumping”.

I see a visual flicker, of what’s on the screen jumping vertically, for a very brief moment, then there’s about two seconds after in which the laptop has frozen.

I uninstalled arc-theme, and the GTK2 engine, and went back to “default” - and this caused Debian to lock up!

I did a hard reboot, but the display jumping and then laptop freezing persists - it only happens if I’m actually doing something, say with the mouse pad.

(There’s a bit more to add, but I’m forbidding from posting more. Yay.)

(Maybe I can get in one more line - I have noticed on boot I’m getting “GPU failed to initialize, declaring it wedged”. Turning off PSR seems to have solved the problem, but I suspect it’s masking the real issue; why the GPU is now unhappy.)

Ok here’s a reply that may allow you to post again.

By the way read other topics to raise your user status etc.

Thankyou : -)

Just addding that I’m seeing the same thing with Fedora 36 (6.0.9-200.fc36) on a 12th gen DIY i5. For me it seems to happen most often on resume from suspend when on battery power – after opening the laptop, I can grab any window and move it around quickly in circles for a few seconds, and this will generally make the freeze/jump/flicker thing happen.

I’ve found that, when it happens, I can sometimes hit the power button to force a suspend, then hit it again to resume, and after this the problem seems less severe. But haven’t played enough with this to say for sure.

Some topics on the forums here seem to address this problem or similar ones, but not sure if my problems are the same as those (or the same as yours, but it definitely sounds similar). Haven’t yet contacted Framework support since I’m not sure what they’ll be able to do.

So, I reinstalled from scratch, and I’ve had it happen exactly once since then - it’s been two days. PSR is enabled. I don’t think I have it now; but i have no idea why not.

Sometimes starting off with a clean slate is the fastest approach to resolution. If it happens, check dmesg to see if anything interesting appears.
