Title:
  running LightDM in test mode doesn't work

Status in “lightdm” package in Ubuntu:
  New

Bug description:
  As described on https://wiki.ubuntu.com/LightDM, I should be able to
  run lightdm --test-mode in a console. However, when I try that, I
  first get this error:

  matthijs@Simba:~$ lightdm --test-mode
  Running inside an X server requires Xephyr to be installed but it cannot be found.  Please install it or update your PATH environment variable.

  When I then install the xserver-xephyr package and try again, a small
  window opens for less than a second and then closes again. No errors,
  no testing environment. Nothing.
