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.

Tried 510.60 as well and the problem is persistent.
