I have loaded virtual gl on a RHEL 7.9 machine with a quadro rtx 4000 card.
I also have a 7.8 machine with the same card. Only getting 1FPS running
GLXgears through VGL.
These machines are identical, but one was built a few months ago. I never
noticed the slow frame rate, because the machine isn't production yet.
I got this error while setting up the new machine and I am not sure if I
got it on the other one during setup. I dropped to init 3 and tried to run
the command, but it fails too. I also killed all X running to try and run
the command with no luck.
Any help would be appreciated.

Done. You must restart the display manager for the changes to take effect.
IMPORTANT NOTE: Your system uses modprobe.d to set device permissions. You
must execute rmmod nvidia with the display manager stopped in order for the
new device permission settings to become effective.
