[SOLVED] SDDM fails to start Plasma Session

Hello there!

I've got a problem with starting my KDE Desktop Environment after trying to log in with SDDM. After I type in my password, the cursor becomes a black cross and nothing happens, the login screen just stays there. However I can CTRL+ALT+F2 to get to the tty2 command line.

Things I already tried:

Since zsh is my default shell I already checked the Xsession file and everthing is as it is supposed to be acording to this post: https://github.com/sddm/sddm/issues/352

I already removed the ~/.Xauthority file

I already checked if the theme is the cause. Changed from breeze to archlinux-simplyblack

And I tried to start sddm with sudo systemctl enable sddm and sudo systemctl enable sddm.service

I am the only user (except root) and use the Plasma5 DE

I heard about some GPU related issues and my GPU is a [AMD/ATI] Radeon HD 4225/4250 according to lspci

I am looking forward to any suggestions!

Re: [SOLVED] SDDM fails to start Plasma Session

If you suspect zsh could be causing the issue, try switching to bash and see if the problem persists.
Can you start X without DM using startx?

Ok I tried changing back to bash and rebooted, but it didn't change anything .... wouldn't make sense actually since it's not my first time rebooting since using zsh

startx returned;

xauth:   timeout in locking authority file /home/(user)/.Xauthority
.....
SocketCreateListener() failed
....server already running
.....
xinit: giving up
xinit: unable to connect to X server: Resource temporarily unavailable

and the ~/.Xautority file isn't there anymore

the only thing that changed on my pc is that I installed another Linux distro on another partition without overwriting the MBR so grub still works and since I can open tty2 CLI nothing is fundamentaly brocken ......(only had to do swapoff mkswap swapon)

but like said I don't suspect this to be related ...... or am I wrong?

Re: [SOLVED] SDDM fails to start Plasma Session

did you edit ~/.xinitrc to start kde? https://wiki.archlinux.org/index.php/KD … ing_Plasma
have you been able to start X via any DM or startx before?

post the full output, and ~/.local/share/xorg/Xorg.0.log, if startx still fails.

also please use code-tags when posting code as per https://wiki.archlinux.org/index.php/Co … s_and_code

Ok so my xinitrc is in /etc/X11/xinit and did not contain "exec startkde", so I added it and it still failed with the same output as before.

have you been able to start X via any DM or startx before?

Well SDDM and Plasma worked before and I never had to manually use startx. Other than that I am not sure what you mean ....

post the full output, and ~/.local/share/xorg/Xorg.0.log, if startx still fails.

The full output is:

xauth: timeout in locking authority file /home/matze/.Xauthority
xauth: timeout in locking authority file /home/matze/.Xauthority
xauth: timeout in locking authority file /home/matze/.Xauthority
xauth: timeout in locking authority file /home/matze/.Xauthority

Re: [SOLVED] SDDM fails to start Plasma Session

Ok so I came to the conclusion that SDDM is a mess. So I switched to GDM and everything works .....mor or less.

Thank you ooo for your help!
