Are you using the default theme? Could you try enabling debug mode in the config and then check the log for output (/var/log/lightdm/seat-0-greeter.log)

slice commented 7 years ago

Yes, I am using the "antergos" theme.

This was in the log file:

It looks like it can't find any background images, which makes sense because I am using stock Arch instead of Antergos. I'll try putting some images in /usr/share/backgrounds and see what happens.

Alright, creating /usr/share/backgrounds and putting in a wall.png file in there made the greeter work, not sure which as I didn't bother to check. It just displayed a black background though -- I reckon its looking for certain files in the directory.

For the record, when it wasn't functional it would display "an error occurred [something] logon process" and clicking on the first two buttons would just re-display the dialog and the "Cancel" button would just dismiss the dialog, leaving me with a broken greeter.

One last thing -- thanks for an awesome LightDM greeter! :)
