I use i3 WM and lightDM with gtk-greeter.
I am trying to change my greeter to mini-greeter.
in /etc/lightdm/lightdm.conf and
user = MyUserName
It partially worked because I got the expected greeter interface when I rebooted, but when I entered my password it didn’t do anything. I therefore came back to gtk-greeter.
Why changing the greeter made lightDM not start i3 and how to fix it ?
