Eugene,
I have purged and re-installed your PPA as you suggest in comment #20, but the problem is back:
The session does never start, and in ~/.xsession-errors I see:

  gnome-session-flashback (3.8.0): attempting to launch gnome-session at 2014-09-22T13:14:34+0200
  gnome-session-is-accelerated: No hardware 3D support.
  gnome-session-check-accelerated: Helper exited with code 256
  gnome-session-is-accelerated: No hardware 3D support.
  gnome-session-check-accelerated: Helper exited with code 256

  ** (process:12360): WARNING **: software acceleration check failed: Child process exited with code 1

  ** (gnome-session:12360): CRITICAL **: We failed, but the fail whale is dead. Sorry....

Has something changed with your PPA?
