It seems that from systemd 256 onwards, lightdm cannot properly log into homed user accounts.  At least in X sessions.

It keeps in a loop of "getting password --> (trying to) logging in --> black journaled screen --> getting back to the first step asking for password again"

It can't read ~/.Xauthority, tries to find it at /.Xauthority instead.  

lightdm unit logs says:
~~~
Error writing X authority: Failed to open X authority /.Xauthority: Permission denied
~~~

It doesn't seem to be related to https://wiki.archlinux.org/title/LightDM#Infinite_login_loop

Also, there's an open issue related to this in lightdm's github repository


Is there anyone who is experiencing the same issue?

Hi Abnraham,

maybe we share the same problem.

Try to switch to a text console (e.g. CTRL+ALT+F4) and login as the desired user. Switch back to lightdm (ALT+F7) and try to login.

That works for me.
