--- Comment #3 from Roderick Colenbrander thunderbird2k@gmx.net 2007-10-29 10:24:33 --- The gpu detection works based on the advertised GL extensions and later on the renderer string. The glxinfo output looks correct and it should not fail unless we failed to retrieve this GL info. I have seen this happen a number of times for ATI users but then opengl initialization failed too. Try to run using +wgl,+d3d_caps hopefully that reveals something.
