Have you checked the file pemissions in

hi

i´ve changed the permissions, but it didn´t help (assuming i don´t have to reboot!?)

in my /etc/udev/rules.d/50-udev.rules is nothing about nvidia....
i´ve added the line you have in it, but also doesn´t help

thanks,

To be in a group you need to log back in. Do a strace on glxgears.

as user i also get an error "dev/null permission denied" when logging in or starting x. does it belong together? but changing permissions doesn´t solve the problem.
