Display manager kicks me back to login prompt after correct password

sadorowo · 2023-09-13 05:50:09

I'm using KDE Plasma. Everything was working fine until yesterday. I messed up something.

I tried to completely reset pipewire, because my USB microphone stopped receiving input. So, I deleted pipewire directory (/usr/share/pipewire) with .so file(s), and then completely removed ~/.cache. One of these actions was wrong I think:/

After successfully entering my password, the screen goes black, and then returns me to the login prompt. I've tried SDDM and LightDM with lightdm-gtk-greeter. The same issue in both DM.

I can't log in as root either.

When I'm logging in via terminal, everything works fine.
I'm getting this message when using sudo lightdm --test-mode:

failed to use bus name org.freedesktop.displaymanager: do you have appropriate permissions?

Also, I can't use lightdm --test-mode without root - i'm getting permission related issues.

I'll post logs and needed files when I'll return home.
Thanks for support. I don't want to lose my files, but if there is no other way, I will chroot, reinstall the system and be more careful next time.

Get rid of the nvidia-settings generated cruft.

Doesn't look like the session-breaker, though.
Please post your complete system journal for the boot after trying to start KDE:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

here it is

edit: i renegerated my xorg.conf using nvidia-xconfig. Issue still persists. I also tried to load my config from the old backup - this didn't helped too.

EDIT 2
issue fixed, I reinstalled nvidia and removed nvidia-settings. Also reinstalled libpulse because in .xsession-errors i had this line:

error while loading shared libraries: libpulsecommon-16.1.so: cannot open shared object file: No such file or directory

But the files were there. I tried using chmod on /usr/lib/pulseaudio and boom, working now.

thanks for support and I'm sorry for inconsistent statements in some places, but I'm just starting my adventure with Arch.

Don't do that, remove any /etc/X11/xorg.conf you create this way.
The autogenerated config breaks more things than it helps.

But the files were there. I tried using chmod on /usr/lib/pulseaudio and boom, working now.

Neither PA nor pipewire are running in the journal you posted, but at least the pipewire socket is active
=> get rid of pulseaudio, use pipewire and pipewire-pulse

now I only hear noises when doing the microphone test

Then check eg. "alsamixer -D hw:0" for the microphone settings.

The journal doesn't contain any session starting errors - nor indication that any session ever successfully started.
You're running SDDM on wayland and are trying to start plasma on X11, could be because of the simpledrm device.

Remove the xorg.conf, enable modesetting, replace pulseaudio w/ pipewire-pulse, reboot and report back w/ an udpated journal and X11 log.
