Slick Greeter (LightDM) showing black screen

Help Desk Application Help
1

My Slick greeter only shows black wallpaper by default, but when I run lightdm -d --test-mode, I see my wallpaper.

I applied the wallpaper using LightDM settings (lightdm-settings package from Ubuntu’s repo).

I had an issue that was almost the same… I changed the picture to a PNG file and it worked

Didn’t work :frowning:

try re-installing?

Open the config file with nano or micro or whatever terminal editor you prefer.

sudo micro /etc/lightdm/slick-greeter.conf

There should be a line for the wallpaper.

background=/home/YamiYukiSenpai/Pictures/my_slick_wallpaper.png

Just change that line to point to whatever you wish the image to be.

Checked and it’s already changed.

If you have it correctly set up in the config, try purging the GUI you installed. It is not needed and may be introducing a conflict somewhere.

I got the [Greeter] to show after renaming slick-greeter.conf that LightDM Settings created to lightdm.conf. Didn’t work :frowning:
