Title:
  ubuntu 14.04 ltsp-server /etc/X11/Xsession.d/40-ltsp-server
  DESKTOP_SESSION breaks lubuntu-desktop login

Status in ltsp package in Ubuntu:
  Fix Released

Bug description:
  DistroRelease: Ubuntu 14.04
  Package: ltsp-server 5.5.1-1ubuntu2

  
  The following code in `/etc/X11/Xsession.d/40-ltsp-server` causes issues with dash `export ...` expansion as regards LP#139097 :

      DESKTOP_SESSION=$(echo $1 | sed "s/gnome-session --session=//g")

  Given the following `/usr/share/xsessions/Lubuntu.desktop` :

      Exec=/usr/bin/lxsession -s Lubuntu -e LXDE

  Attempting to login to the Lubuntu desktop session results in the
  following error in `~/.xsession-errors` :

      /etc/X11/Xsession: 6: export: -s: bad variable name

  Presumeably due to the `DESKTOP_SESSION` being set above breaking in
  `/etc/X11/Xsession.d/70gconfd_path-on-session` :

      export MANDATORY_PATH=${GCONF_PREFIX}/${DESKTOP_SESSION}.mandatory.path
      export DEFAULTS_PATH=${GCONF_PREFIX}/${DESKTOP_SESSION}.default.path

  Commenting out the culprit DESKTOP_SESSION=... assignment lets me
  login to the Lubuntu desktop again.
