[Pkg-xfce-devel] Bug#844295: [lightdm] "FAILED to start Light Desktop Manager" errors after dpkg-reconfigure lightdm and choosing another desktop manager

[Laura Arjona Reina]

Package: lightdm
Version: 1.18.2-2
Severity: normal

Dear maintainers

Thanks for your work in lightdm!!

I just upgraded my desktop from jessie to stretch.
I use lightdm and KDE plasma.
I did:

dpkg-reconfigure lightdm

and chose "kdm" as my default desktop manager, just to try kdm.

Then when I boot the PC, I get "FAILED to start light display manager" 
errors.
If I do dpkg-reconfigure lightdm and I choose lightdm again, the errors 
disappear.

I guess the service is not correctly disabled when I choose a different 
desktop manager.

If I should report this bug against a different package, please tell.

Best regards
