Public bug reported:

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?
