After update the problem remains (now I am using kernel 2.6.38-7.38). Unity last for minute or two after login, then it freezes. I logged in to the console, tried to run metacity --replace, or compiz --replace, but nothing helps. Restart of gdm "worked", X was restarted, but screen was black. I was able to login (it was verified by login sound), but black screen is useless:-)
Running ubuntu with Classic session (no effects) seems stable, if metacity crashed, I am able to restart it from console. After that opengl application do not work.
