Hi, I have found with the latest NVIDIA drivers that I keep getting error messages indicating that /dev/nvidiaactl could not be opened because of restrictive permissions. So, following the README, I edited /etc/security/console.perms (removed line with <dri>) and ran chmod 0666 /dev/nvidia* followed by chown root /dev/nvidia*. The problem is I have to do this after each reboot. Is there a way to make this stick? paul
