What you guys’ graphics memory allocation setting in BIOS?
I was having the same problem and noticed maxed out memory on integrated graphics. Changed the memory allocation from “Auto” to “Gaming” and I haven’t seen the issue since.
It’s hard to verify this was the cause, but it’s worth a try.
Hmm, I’ll check if memory is maxxed next time this happens. What utility are you using to check?
I do have mine set to Auto as well iirc.
I’m on Fedora using nvtop. It got to a point where the history graph it displays would get “choppy” and that seemed suspicious. I think Auto was allocating 500MB to graphics, now it’s allocating 4GB, I think.
I haven’t had this issue pop up in a while (although I have been rebooting frequently due to wifi not working on resume), however last night I managed to trigger it twice when an external display device had a bad connection. And it seemed to be completely frozen, although I didn’t try to ssh to check. If I have time today I’ll try to repro.
