all you have to do is detect a gnome session... :)

DESKTOP_SESSION isn't set from an LDM session, and given that's the primary
use-case for LTSPFS, and that LDM would only be able to set that if the user
manually selected the session, either from the LDM user interface or from
~/.dmrc, i don't think this is a viable option...

from an LTSP thin client on Debian Squeeze:

  env | grep -i gnome
  GTK_RC_FILES=/etc/gtk/gtkrc:/home/ltsp/.gtkrc-1.2-gnome2                                                                                          
  GNOME_KEYRING_CONTROL=/tmp/keyring-qbnkKI                                                                                                         
  GNOME_DESKTOP_SESSION_ID=this-is-deprecated                                                                                                       
  XDG_DATA_DIRS=/usr/share/gnome:/usr/local/share/:/usr/share/           

much less to go on.

i also suspect that many of the other variables tend to change a lot between
GNOME releases, so i'd want to know that the environment variables would remain
consistant for a while, and preferrably work across distros...

live well,
