https://bugs.freedesktop.org/show_bug.cgi?id=111482 --- Comment #10 from Andrew Sheldon --- >I don't know how to interpret your last comment Yeah, I was a bit unclear. I was just indicating that while I can workaround the issue, it can still be triggered on my system as well. E.g. if I switch to 75hz, it will be stuck at 850mhz (even after switching back), so it's possible that the issue can be triggered through different ways (but the underlying issue may be the same). Anyway, I suspect that this bug, the one related to sensor readings (including the 75hz issue), are all related. It's most likely a video bios/firmware issue as it affects Windows as well, and some have even triggered the bug in BIOS settings, with monitors that use 75hz. One thing you could try is booting with a window manager/DE that doesn't use any sort of hardware acceleration. That's the main difference I can figure between my system, and yours (besides the fact I use x370 instead of x570). I would also try a lower resolution just to test, as that's a pretty non-standard res, and might be another way of triggering this bug. -- You are receiving this mail because: You are the assignee for the bug.
