Ubuntu Precise Alternate LTSP

ltsp-client loads 3d session but it is detected as unsupported by unity_support_check.

 * /tmp/unity_support_test.1 exists
 * ~/.xsession-errors contains "gnome-session[1596]: WARNING: Session 'ubuntu' runnable check failed: Exited with code 1"
 * but compiz qnd unity are running

If the user loads unity-2d once, then all other sessions starts with unity-2d.
