I’m facing the same problem where despite the driver installed, the system is not using the graphics card. My laptop also has GP108M [GeForce MX150] card. I’m running Debian 11.nvidia-bug-report.log (209.9 KB)
The driver is installed fine, the nvidia gpu is running in offload mode. You can start applications on it by prepending
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia
