Re: Re: Xlib: extension "GLX" missing on display ":0.0".
I had the same problem on my labtop with ATI Radeon M9. Tried everything that
is suggested in various postlist and nothing worked. Then I found this page
http://www.gmpf.de/english/ and followed it's instuctions and voila! no more
"Xlib: extension "GLX" missing on display ":0.0" but a working 3D OpenGL. :).
All I had to change was <Option "UseInternalAGPGART" "yes"> to <Option
"UseInternalAGPGART" "No"> and restart X.
Hope this helps.
