It happens to me too. Same problem. Related to Chrome or Chromium.
I can add that, if I use ssh to the freezed machine, SSH is active and everything works.
I tried to restart X11, even with "runlevel 3" and then "runlevel 5", but once it has frozen, the GUI never comes up again.
If I use Firefox, it never happens.
I suspect it has something to do with NVidia drivers, but I don't know how to check.
