I just recently reinstalled Ubuntu 12.04 and while I was installing my programs I found I couldn't open Blender. The application wouldn't start. When I typed it in to the console I got this message:
Xlib: extension "GLX" missing on display ":0.0". /build/buildd/blender-2.63+svn46744/intern/ghost/intern/GHOST_WindowX11.cpp:197: X11 glXQueryVersion() failed, verify working openGL system!
initial window could not find the GLX extension, exit!
I'm not sure what to do. I've tried googling the issue but to no avail. Any help??!
