Hi all,
somehow my greeter+wm is broken. I can’t login in the gui. I have to switch to another tty and manually start X. That tells me my xorg config is sort of fine. When I switch to tty I get the following error
Error: unable to open display
After running startx my desktop enviroment boots and I’m able to lock the session and relogin in the same session. I’ve deleted the session cache files and ran chown -R user:user on my home directory but that also hasn’t had any change so I dont think it’s permission based.
Might have ran sudo yay like a numbskull >_<? Anyhow I’m pretty bad at troubleshooting X issues and Id like some help on where to look.
Also created a second user but I’m unable to login with another user aswell.
edit:
To make debugging a little bit easier I installed xorg-zephyr. running light-dm --testmode --debug I got the following error.
+3.63s] DEBUG: Session pid=3649: Authentication complete with return value 0: Success
[+3.63s] DEBUG: Authenticate result for user xxxxxx: Success
[+3.63s] DEBUG: User xxxxxxxxxxx authorized

[+3.63s] DEBUG: Session pid=3649: Exited with return value 0
[+3.63s] DEBUG: Seat seat0: Session stopped
Somehow my session request from greeter to xfce is broken?
Switched from lightdm to sddm and that enabled me to login via the gui again. So clearly the issue is in lightdm 
ugh
