my normal user accounts cant use GL

If I run X as root, I can use all things GL.  Any normal user account I have though cant.  I get an operation not permitted error.  I have 9800 Pro using the latest fglrx driver.  Any help would be appreciated.

Re: my normal user accounts cant use GL

the only things I can think of are user groups and where the xorg.conf file is, if you have an xorg.conf in the home directory it will override the one in /etc/X11/, check your /root/ and /home/(user) folders for an xorg.conf.  either you have one with all the right settings in /root/ and none in /etc/X11 or a good one in /etc/X11 and a bad one in /home/(user).  Hope this helps

Add your user to the video group.
# gpasswd -a USERNAME video

And make sure you have :
Section "DRI"
        Mode 0666
EndSection
in your xorg.conf

Yeah was missing DRI in xorg.conf, thanks.  Knew I was missing something simple

Re: my normal user accounts cant use GL

I feel I should mention that this error and solution were described in the troubleshooting section of the ATI Radeon & Kernel 2.6 wiki page.     I've made alot of changes to that page recently, and it's actually useful once again.
