I had this exact same problem for quite a while:
Laptop: 11th gen FW13, i7-1165
OS: Latest Pop OS 22.04 LTS
Kernel: 6.9.3-76060903-generic
What consistently triggered it was just yanking the brightness up and down with the mouse. Depending on… whatever, it would hang the screen after a few slides. But it would also happen with videos in Firefox (like Youtube) and when using night light.
I re-installed Pop OS last weekend as I didn’t have the problem when using the live USB. So I thought a fresh installation might fix it.
It did, until I switched to Wayland again. On the live USB I probably used Xorg. Same problem started again. Nothing was fixed at all.
I didn’t fix the problem before this weekend for a long time, as it only happened when I used the laptop stand-alone (no external display attached).
Frustrated as I already re-installed Pop, I now really wanted to fix it.
I discovered this issue, which I didn’t find before, saying to add i915.enable_psr=0 to the kernel boot options.
I also removed nvidia-drm.modeset=1 as it popped up in the boot options after re-installing Pop. I don’t have an nVidia-GPU, so I thought it made sense to remove it. I don’t know if it was related though, but I don’t remember it being there before the re-install.
So after adding the i915 option with:
sudo kernelstub -a "i915.enable_psr=0"
And remove the nVidia option:
sudo kernelstub -d "nvidia-drm.modeset=1"
My boot options now look like this (view them with : sudo kernelstub -p):
loglevel=0 systemd.show_status=false quiet splash i915.enable_psr=0
The screen hanging hasn’t occurred since.
