Is the discussion http://irclogs.ubuntu.com/2014/08/11/%23ubuntu-
mir.html ?

If u-s-c doesn't always accept the --vt option then then it's going to
fail on kernels that have VT support (which from the above log seems to
be this particular case?). If VT support is available then LightDM
assigns VTs to each server / system compositor so they don't conflict.
In the phone case we only have one system compositor but theoretically
you could also start an X server so LightDM has to assign VTs if they
exist.

There seem to options to solve this properly:
1. u-s-c always supports --vt and only applies it for backends that require it.
2. u-s-c backends that use VTs reads the XDG_VTNR environment variable.

I would recommend option 2 since VTs are going to be a legacy feature in
the future anyway and other systems seem to be using XDG_VTNR over
command line options.

Title:
  [regression] unity-system-compositor can't start (Unknown command line
  options: --vt 1) via lightdm on Android

Status in Light Display Manager:
  Incomplete
Status in Mir:
  Invalid
Status in Mir 0.6 series:
  Invalid
Status in Unity System Compositor:
  In Progress
Status in “unity-system-compositor” package in Ubuntu:
  Fix Released

Bug description:
  From Cemil:
  Sync'ed up 0.6 with devel@r1831 since we were in TRAINCON-0. Everything built successfully.

  Using image #179 with 0.6, mir itself works (i.e. mir-demos & nested),
  but USC has the following error :

  root@ubuntu-phablet:~# cat /var/log/lightdm/unity-system-compositor.log
  Unknown command line options: --vt 1

  The "vt" option is passed in by the wrapper in lightdm, but not sure
  why usc is rejecting it. Without 0.6, usc works fine with the same set
  of args.

  It'd be nice if the AUS, or EUR can take a look on Mon. Follow the
  instructions (updated due to platform versioning) below to install and
  test :
