17.10 upgrade still uses Gtk greeter

I updated from 17.04 to 17.10 and ubuntu mate is still using Gtk greeter.

How can I manually switch to slick greeter?

Try

sudo apt install slick-greeter # just in case slick-greet isn't installed
sudo dpkg-reconfigure lightdm

I only have slick-greeter installed, so it doesn’t do anything for me, but it’s worth a try.

Same for me. Did the 17.04 to 17.10 upgrade. slick-greeter 1.0.8-2 was already installed. And GDM is still the default, even after doing sudo dpkg-reconfigure lightdm

Found it…

sudo cp /usr/share/lightdm/lightdm.conf.d/60-lightdm-gtk-greeter.conf /usr/share/lightdm/lightdm.conf.d/60-lightdm-gtk-greeter.conf.backup

sudo nano /usr/share/lightdm/lightdm.conf.d/60-lightdm-gtk-greeter.conf

Replace greeter-session=lightdm-gtk-greeter with greeter-session=slick-greeter

lightdm --show-config now shows H greeter-session=slick-greeter

Then Reboot

Nice!
