Nvidia Prime and DRM activation problems.
Nvidia Prime and DRM activation problems.
You're trying to switch your drivers to NVIDIA DRM for better performance, but you're encountering several issues. It seems the system is still using the standard NVIDIA driver instead of DRM. The problems you're facing include rapid switching between TTY1 and GUI, flashing screens, and GPU usage not reflecting in monitoring tools. You've already tried editing environment variables, checking XGL, and using different driver versions, but nothing seems to resolve the issue. It might help to verify that your GPU is properly detected and that the correct driver is loaded. If you're on a headless setup, ensure that the necessary services are running and that the environment variables are correctly set. You may also want to consult the NVIDIA support forums or community for more targeted solutions.
