At least on my system, slick was the default from the beginning, though I suspect that had something to do with me overwriting my old Mint installation, though I'm not sure why it would keep display configuration settings from the OS it's overwriting. Could be lightdm comes packaged standard and is default and I'm just an idiot
Long story short, I'm only speculating here after looking through my own system.
Make sure lightdm is installed, and in its directory (/usr/share/lightdm/lightdm.conf.d/
) I have a file called 60-slick-greeter.conf
that has only this in it:
Code: Select all
# We only exist to override the default greeter to be the slick-greeter
which seems to do exactly what the comment says - overrides the default greeter.
