For GDM, it needs at least
https://gitlab.gnome.org/GNOME/gdm/-/merge_requests/171#note_1429657
to protect issue happens.
For Mutter, a related patch is
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2341/diffs
could cover if nvidia is secondary GPU.
For nvidia-driver, u-d-c, we need to follow
https://download.nvidia.com/XFree86/Linux-x86_64/510.54/README/powermanagement.html
to setup the parameters after some checks.
I appended the parameters:
options nvidia NVreg_TemporaryFilePath=/run
options nvidia NVreg_PreserveVideoMemoryAllocations=1
and then the problem solved.
