Screen refresh difficulties

I agree... Don't get me wrong. But it may be separate and that needs to be acknowledged. The kernel does govern both as it is what contains the drivers.
You may try the 5.8 kernel.
Or the 5.14 kernel. I would go for 5.8 first, just to be sure.

I tried the 5.8, which caused even more flashing of my screen, I think post 16 was related to it :slight_smile: I tried 5.8.0-69 and 5.8.050800, so I'm gonna check what 5.14 might offer me!

@Aravisian did you mean 5.4?

No, I meant 5.14. Get above the 5.11 regressions and other fiascos.
There is still one remaining fiasco to hurdle in 5.14, however. The libc6 compiler dependency problem.
To that end...
I recompiled a 5.14 headers file to allow it to be installed on Zorin OS.

Woah, if you would be so kind, I would love to give it a try. Could you PM me the info?

Ehh, I think I found it :smiley:
Adding i915.enable_psr=0 to grub completely removed the screen stutter! No idea what I did but it made it go away instead of nomodeset!
In the newer kernel that is!

Just for brevity - I can answer on behalf of the O.P. - Grandjaeger is using the 5.11.0-37 kernel and the solution of changing the resolution worked on that kernel.
