Title:
  GDM on Lucid fails to compute MIT-MAGIC-COOKIE for use by remote x
  client

Status in “gdm” package in Ubuntu:
  Expired

Bug description:
  Binary package hint: gdm

  Output from system operating under Ubuntu 8.04 (Hardy) follows:

  	ajax@Pluto:~$ xauth list
  	Pluto/unix:0  MIT-MAGIC-COOKIE-1  7adf6a3bc46df973a859107fc753fd46
  	localhost.localdomain/unix:0  MIT-MAGIC-COOKIE-1  7adf6a3bc46df973a859107fc753fd46
  	pluto.my.test:0  MIT-MAGIC-COOKIE-1  7adf6a3bc46df973a859107fc753fd46
  	pluto.my.test:0  MIT-MAGIC-COOKIE-1  7adf6a3bc46df973a859107fc753fd46
  	pluto.my.test:0  MIT-MAGIC-COOKIE-1  7adf6a3bc46df973a859107fc753fd46
  	localhost:0  MIT-MAGIC-COOKIE-1  7adf6a3bc46df973a859107fc753fd46
  	ajax@Pluto:~$

  Output from the same system after being upgraded to Ubuntu 10.04
  (Lucid) follows:

  	ajax@Pluto:~$ xauth list
  	Pluto/unix:0  MIT-MAGIC-COOKIE-1  b2454808aa25b2ac47f30f72b0d50946
  	ajax@Pluto:~$

  The X server display of the former system (Hardy) allows access for X
  clients running on remote hosts, whereas the upgraded system (Lucid)
  does not.  Of course this can be explained because there is no MIT-
  MAGIC-COOKIE available for use by the remote system.  Generation of
  the necessary cookies is done by the display manager which in this
  case is the GNOME Display Manager (GDM).

  Please notice that this report is being submitted with my system being
  operated by Hardy which is the system that works correctly.  I had to
  restore my system from Lucid which is the failing system to Hardy in
  order to produce the evidence (above) which demonstrates what is
  broken on Lucid.
