Bug Description
LightDM currently uses /dev/console for VT operations. In Ubuntu 16.04 this does not appear to work anymore. Switching to /dev/tty0 works, and this matches what logind and GDM use.
When these operations don't work this can affect the ability to switch between sessions.
There doesn't seem to be any documentation on what the correct device to use for VT operations is, so matching other software is probably just reducing the risk of hitting bugs.

This may be the cause of ongoing VT switching issues (bug 851612).
