File '50-local.permissions' (as I described above) works for me by adding the single line: -------------------------------- nvidia*:root:root:0666 -------------------------------- I can successfully run glxgears and tuxracer. The permissions file would only be read when when the /dev/nvidia* inodes were being created (e.g., upon a reboot). I believe it would be done during execution of udev.static from the initrd. Have you rebooted? After a reboot, what permissions do you have for /dev/nvidia* ?
