Periodically when firefox is running my laptop freezes for a few seconds. I decided to try running firefox from terminal to see what shows up when that happens, and I always get:
[GFX1-]: GFX: RenderThread detected a device reset in PostUpdate
I’m not sure but a lot of us are running with options i915 enable_psr=0 set in /etc/modprobe.d/i915.conf. I think that you will need to regenerate your initrd after adding that, I think with sudo update-initramfs -u. You can sudo cat /sys/module/i915/parameters/enable_psr to check to make sure that it is set correctly.
I’m running Linux 5.19.17-051917-generic #202210240939 SMP PREEMPT_DYNAMIC Mon Oct 24 09:43:01 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux on Kubuntu 22.04 with the above and have no graphics problems.
Sorry for the late update, but I actually seem to have resolved my issue by turning off hardware acceleration in firefox. Since I made this update a few weeks ago, I haven’t had any weird freezing events.
