Update broke KDE wayland login (Slowroll)

[Spaceboy]

After doing a sudo zypper dup I’m unable to login to KDE wayland session (screen turns black and then boots back to the login screen). KDE X11 works fine.

Update log

Any ideas?

Review this topic first:

Wayland will not start

To start with, create another user account while in the X11 Plasma session, then log out, change to Wayland session and login as the new user. Does that work, or same issue?

FWIW, a similar recent topic:

Plasma Wayland stopped working - how can I investigate the cause?

I was quite happy user of Plasma on Wayland. It came automatically with KDE Plasma 6.0 and worked out of the box. But some time ago, I suspect after update to KDE Plasma 6.1, it stopped working. When I select Plasma on Wayland in the system login screen, in SDDM, it shows briefly a black window and then returns back to SDDM. I was waiting if some system update would fix it. But it’s not happening so I guess I have to start digging around myself. I do have Nvidia GPU, in addition to Intel iGPU.…

Based on the update log you shared, Mesa (from Packman) is the likely cause here.

[Spaceboy]

ok, well i downloaded everything Mesa related from Tumbleweed repos rather than Packman, no difference whatsoever, still same login issue so I’m guessing it’s probably something other than Mesa (at least you would think so given that all mesa drivers are now from openSUSE?).

[Delforo]

What Nvidia driver are you using?
Can you share the output of inxi -G

[Spaceboy]

No Nvidia drivers.
inxi -G:

No, i rolled system back, removed the Packman repo, done a zypper dup, 14 packages changed vendor to openSUSE, after doing a full update and reboot the same issue of not being able to login to KDE wayland (was able to before zypper dup issued).

Did you try the approach described here?

Wayland will not start

Just guessing here…the ~/.config/plasmarc file may also be worth checking. You could get additional diagnostic information by starting the Plasma Wayland session by hand from a TTY (runlevel 3 logged in as user). dbus-run-session startplasma-wayland > wayland.log

Then review the wayland.log file for errors.

[Spaceboy]

OK, creating a new user didn’t make a difference like it did for him. Will try dbus-run-session startplasma-wayland > wayland.log from run level 3 later see if it brings anything to light.

OK, I get “could not create wayland socket” when i rundbus-run-session startplasma-wayland, and wayland.log is empty.

[Spaceboy]

org.kde.ksplash exited with status 1 is one error.

[Spaceboy]

Also, i get pretty much the same screen as here: https://forums.opensuse.org/t/wayland-will-not-start/172287/14

[deano_ferrari]

Unfortunately, none of that provides enough information to allow others to help with progressing further.

@Spaceboy

Nothing precedes that error? Vague snippets of information don’t provide enough of a picture here.

[deano_ferrari]

Does sudo zypper ve --dry-run show any package inconsistencies?

[Spaceboy]

@deano_ferrari

sudo zypper ve --dry-run

Nothing:

Since it’s not writing to wayland.log as the system is waiting for something to happen which never does then the only option would be to provide screenshot via my phone?

[deano_ferrari]

Better than nothing I suppose.

[deano_ferrari]

The above checks out as expected ^^

[Spaceboy]

@Spaceboy

dbus-run-session startplasma-wayland > wayland.log

nothing in log, just get this screen:

Review
journalctl -b | egrep -i "wayland|plasma"
You can examine form a working Plasma X11 session.
