[Peter Schüller <1300914@xxxxxxxxxxxxxxxxxx>]

Recently the workaround I previously described stopped working:
logging out of the session and logging in back does not work anymore:
only the lightdm screen becomes visible on the projector, the session
is never visible! (After plugging out the monitor the first time, or
after shutting down the beamer the first time. Before that it works.)

Title:
  External screen undetected after first plug

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  On Ubuntu 14.04, the external screen plugged on VGA is detected and get activated correctly.
  However, if I unplug it and then replug it later, it is not detected anymore and the screen receives no signal.

  A way to get it back to work is to reboot or simply suspend the
  computer.

  Sorry but I have no idea of what package is handling that.
