Title:
  lightdm freeze

Status in “lightdm” package in Ubuntu:
  New

Bug description:
  Until yesterday I was using 11.04. Unity worked fine with GDM. Then I
  installed 11.10.

  After boot, lightdm puts up the greeter OK. If I select "Ubuntu-2D"
  (Unity 2D) from the login box, then after a 30-second wait I have a
  usable Unity desktop. However, the network indicator falsely states
  that networking is disabled. If I log out, lightdm freezes (I get the
  text-mode screen with "checking battery state" etc). When I examine
  the process list, it seems that there are two lightdm processes, one
  of which is preventing the other from restarting. If I kill them,
  lightdm restarts.

  If I try to log in using Unity-3D, however, there is a long wait
  before the desktop appears. I get no launcher bar on the left - not
  even when I press the "windows" key. Nor does the rightmost logout
  widget appear on the top bar. I have a similar problem on logout - no
  greeter appears and I'm left in an unresponsive text mode screen.

  If I kill all the lightdm processes and start gdm, everything is fine.
  I can start Unity-3D and indeed any other desktop with no problems.
  And it's much, much quicker.
