fellow Ubuntu Enthusiasts! I recently installed LightDM via sudo apt install lightdm and then installed lightdm settings tool via sudo apt-get install lightdm-gtk-greeter-settings
And now, LightDM looks all weird. It doesn't have the look that it used to with a fresh lightDM install. Can somebody please help me to restore all the settings?
My lightDM theme looks like this right now:

enter image description here I'm on Ubuntu 20.04, Focal Fossa, by the way.

LightDM comes in different flavours. The first screen indicates that you have the lightdm-gtk-greeter activated.

You control those settings settings in the /etc/lightdm/lightdm.conf:

[LightDM]
run-directory=/run/lightdm

[Seat:*]
greeter-session=lightdm-gtk-greeter
user-session=xfce
session-wrapper=/etc/lightdm/Xsession

In addition to that are "slickgreeter" or "unity-greeter" which you may have to install before configuring them.

Ubuntu on the other hand uses the GDM (GnomeDisplayManager) which has a complete different look and feel.

So I'd go for the slickgreeter -I think Linux Mint uses that - to get a close look to your second screen

  • Thank you for your quick response. How would I install unity-greeter, or slickgreeter? When I first installed lightdm, it looked exactly like the second picture. I have also reinstalled it a few times, and have had no luck restoring it. There is also no lightdm.conf file there. Nov 4 '20 at 18:18
  • I figured it out! I had to create a new lightdm.conf file. And had to construct it manually. +1 thanks for your answer though! It worked after I created my own config file. Nov 4 '20 at 18:34
  • Maybe distro dependent. Since ubuntu does not have lightdm by default that may be the reason. Glad you got if figured out
