Title:
  After logout Xorg stays stuck in tty_ld

Status in “mountall” package in Ubuntu:
  Confirmed

Bug description:
  Precise is not able to restart Xorg after a logout in any of my
  machines. After I log out, the Xorg process stays stuck in tty_ld. ps
  shows:

  4     0  1258  1187  20   0      0     0 tty_ld Ds+  tty7       0:07 [Xorg]
  0  1000  2977  2959  20   0   9396   916 pipe_w S+   tty1       0:00 grep Xorg

  Since tty7 remains busy, no new desktop manager and Xorg start up
  automatically.

  Dmesg last line seems to be relevant:
  [  193.702121] tty_ldisc_hangup: waiting (Xorg) for tty7 took too long, but we keep waiting...

  It seems that a password prompt for some smb/cifs mounts that are not
  marked as noauto are causing the issue.

  //nasi/data             /home/gema/data         cifs    user,user=gema
  0       0

  Adding noauto works around the problem,

  //nasi/data             /home/gema/data         cifs
  noauto,user,user=gema  0       0
