Comment 3 for bug 822539

Sorry, I forgot about it.
Before uninstalling nvidia-current: something about GLX missing
After uninstalling nvidia-current:

OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile GEM 20100330 DEVELOPMENT
OpenGL version string: 2.1 Mesa 7.10.2

Not software rendered: yes
Not blacklisted: yes
GLX fbconfig: yes
GLX texture from pixmap: yes
GL npot or rect textures: yes
GL vertex program: yes
GL fragment program: yes
GL vertex buffer object: yes
GL framebuffer object: yes
GL version is 1.4+: yes

Unity supported: yes

Also after the update and BEFORE reboot OpenGL stopped working in Java (I'm developing OpenGL game in Java right now). After reboot Unity wasn't working too.

Maybe the solution would be putting older version of nvidia drivers until the bug is resolved (if others have the same problem with them)? The update I installed almost certainly had new version of nvidia-current and probably of Java (I've seen iced tea in there). It was the first update I did in a month though, so I don't know how long the problem was there.
