Title:
  issue with SCREEN_07=shell

Status in ltsp package in Ubuntu:
  Fix Released

Bug description:
  Hello
   Here is the issue,  a workaround was given on https://lists.sourceforge.net/lists/listinfo/ltsp-discuss  . I copied that to the end of this report:
  --------------------------------------------------------
  Problem:
   We've installed Ubuntu 12.04 ltsp server and it is working great for
  gui desktops.

   However we would also need to serve shell only to some clients . [
  That is for stations needing just command line].

   I do have this working in a KVM.   This does what we want:
  [DA:72:E8:40:24:D0]
  # kvm 101  on  home4
   SCREEN_02=shell
   SCREEN_03=shell
   #SCREEN_07=ldm
   SCREEN_07=shell

  
  However for real hardware it has not worked for us.

  On real hardware [ 3 different systems ] we can use ldm,  But when we
  set this: SCREEN_07=shell  , the screen hangs forever at the
  screen that shows  " Ubuntu ...."

  
  --------------------------------------------------------------
  Workaround: 
  In /opt/ltsp/i386/etc/init/ltsp-client-core.conf there's a line that reads:
  /bin/plymouth quit --retain-splash || true

  I'm guessing that this is supposed to stop plymouth but retain the image 
  on screen, so that there's a smooth transition to X.
  And since you're not using X, there's no code to clear the retained 
  plymouth image.

  I'd suggest for you to file a bug in
  https://bugs.launchpad.net/ubuntu/+source/ltsp
  in order for some developer to see/fix that part of the code,
  and in the meantime to remove "quiet splash plymouth:force-splash 
  vt.handoff=7"
  from /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default

  
  --------------------------

   remove "quiet splash plymouth:force-splash vt.handoff=7"   fixed the
  issue here.
