Package: lightdm
Version: 1.18.3-4
Followup-For: Bug #887773
Dear Maintainer,
I had the same problem with lightdm. Installing light-locker seems to be
solving it.
If I lock and switch ttys without light-locker, lightdm creates a new seat.
Here is the output of the systemctl for it:
● lightdm.service - Light Display Manager

preset: enabled)

With light-locker running everything seems to work as expected. No additional
seat is created.
