Hi, 
 
Another guess, it might be that your update of Ubuntu has corrupted your 3D video driver, therefore your OpenGL will not work, not say other 3D functions, since either Nvidia or ATI will requre some kernel devel or other very sticky thing to compile, especially, when you update the kernel. So you might try re-install the 3D graphic driver before re-install qglviewer, then re-compile YADE. If you cannot run glxgears, as Vaclav said, that's probably the case. 
PS: I have one laptop with Fedora Core 4, I am still with Yade 0.10.0, I dare not upgrade:-)

Generally, if GLX is missing, the server will fall back to software
rendering (which is slow by several orders of magnitude - no kidding).
Can you run glxgears from the terminal? Let it run and it will tell you
what is the frame rate after a while - if that is less than a few
hundereds, then your acceleration doesn't work. But in that case you
would see at least something in the primary view. You can also post
output of xdpyinfo to investigate this.

But my first bet would be what Feng suggested: recompile qglviewer,
probably new mesa version with different API was installed.

Regards, Vaclav
