I make installation of the Open Suse Prime driver from this guide :

https://en.opensuse.org/SDB:NVIDIA_SUSE_Prime.

But when I try to switch between nvidia and intel, I use this command :


prime-select intel,

but the result is :

I receive this issue
modprobe: FATAL: Module nvidia_drm is in use.
bbswitch is not installed. NVIDIA card will not be powered off.

What shuld I do to fix it?
