Since the 45.1 update, on screen lock gnome stops/crashes. Awakening the screen takes you back to the login screen, where a new session is started. All opened apps in previous session are gone…
No good logs available.
AMD Polaris 550 GPU, AMD Ryzen CPU. The system is barely usable- I have never seen such a severe problem.
Possibly related to crash/freeze on GPUs related to preempt in KMS GPU driver/module (#3151) · Issues · GNOME / mutter · GitLab, rt thread in mutter.
Ubunutu released a patch here - Bug #2034619 “[amdgpu] gnome-shell gets SIGKILL'd when lock scre...” : Bugs : mutter package : Ubuntu
Is the rt-kms scheduling enabled for Manjaro?
Will try and set the KMS and env variables referenced and post back.
I’ve been experiencing something similar; when I close and reopen my laptop, GNOME crashes and sends me back to the login screen. I’ve tried setting
HandleLidSwitch=ignore in /etc/systemd/logind.conf, but the issue persists. It seems to be GPU related, because the only solution I’ve found is to set the display mode in BIOS to ‘mshybrid’ instead of ‘discrete’.
CPU: Intel i7-13700HX
GPU: NVIDIA 4060
options amdgpu mcbp=0
No crashes so far.
This worked for me. Thanks.
What does this mean/do, though?
It seems the latest mutter has real time scheduling enabled for kernel mode settings for graphics that seems to cause random crashes. This I think changes the real time scheduling to User, so it can be pre-empted… but I am no expert.
