Comment 17 for bug 1166765

Upon looking at the attached .xsession-errors, I don't think this is a compiz bug:

Xlib: extension "GLX" missing on display ":0".
Xlib: extension "GLX" missing on display ":0".

(gnome-settings-daemon:2437): GnomeDesktop-WARNING **: GL_MAX_TEXTURE_SIZE helper quit unexpectedly

(you can confirm similar errors when running glxinfo &)

What is certainly curious about this is that the Xorg logs and xdpyinfo suggest that the glx extension is loaded on the server side, but the currently loaded libGL.so doesn't think it is, so it refuses to create a context and everything dies after that.

What would be curious is to learn exactly what libGL.so the opengl plugin is being linked to. You can figure that out with the following:

ldd /usr/lib/compiz/libopengl.so
