Note how his libGL is already complaining about the inability to load the 
"swrast" (software rasteriser) driver.

The "Unrecognized OpenGL version" message comes from Qt, but the two errors 
before it are from libGL (Mesa). I suppose Mesa complaining that it doesn't 
know how to deal with the remote X connection is normal, but that error about 
swrast is worrying.
