  • did you try dpkg-reconfigure metacity? (never done mysef, but if it fail, maybe the problem is metacity or server X configuration)

  • this is exactly like what my friend faced. and he notice that his session always suddenly logged out if he runs Chrome. did you experiencing this while running a specific program? this is indeed a bug. in your case it seems 'metacity'. try using another windows manager program.

This is unresolved, but relatively rare bug, if you are using gnome-flashback session. Partly because mostly all are using default UI. See more details and subscribe to see if problem is resolved here: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1455916

Temporary fix - don't use gnome-flashback session.
