[Bug 1070357] Re: ldm does not show sessions and cannot start gnome-fallback session

[Roland Giesler]

I installed the ldm from https://launchpad.net/~ltsp-
upstream/+archive/daily, but the problem persists.  As a workaround I
have removed Unity, but at some stage I will have to put it back and
continue testing.

Title:
  ldm does not show sessions and cannot start gnome-fallback session

Status in “ldm” package in Ubuntu:
  Confirmed

Bug description:
  I have recently upgraded my LTSP server to quantal. I have created a
  new thin client chroot with the ltsp-create-client script.

  The thin client boots up fine, but the ldm login screen does not show the correct list of sessions:
  It shows "xterm" and "Ubuntu" only, although gnome-fallback and gnome-classic are present on the server.

  ldminfod on the server returns:

  [...]
  session:gnome-session --session=gnome-classic
  session:gnome-session --session=gnome-fallback
  session:gnome-session --session=ubuntu
  session-with-name:GNOME Classic:gnome-session --session=gnome-classic
  session-with-name:GNOME Classic (No effects):gnome-session --session=gnome-fallback
  session-with-name:Ubuntu:gnome-session --session=ubuntu
  xsession:/etc/X11/Xsession

  So ldminfod detects the sessions all right, but the client does not
  show them on the login screen.

  Putting LDM_SESSION="gnome-session --session=gnome-fallback" into
  lts.conf leads to message 'Failed to load session "gnome-fallback"'.
  So there seems to be a real problem starting the session. However, on
  the server, I can manually start "gnome-session --session=gnome-
  fallback" and it woks fine.

  Why does ldm not detect and/or start the installed sessions?
