When using my laptop's discrete nvidia card Unity works fine, but when enabling the embedded intel card it fails as reported (Intel HD Graphics 3000 (SandyBridge)).
Interestingly when running glxinfo I just get:
Error: couldn't find RGB GLX visual or fbconfig
Xlib: extension "GLX" missing on display ":0".
A month back in the Oneiric cycle or so this intel card worked very well. So looks like a regression in the X stack or intel driver somewhere?
