Cannot log into KDE Plasma Wayland.

I can log into Artix (runit) Plasma x11, XFCE and Awesome. Plasma Wayland just starts, then blackscreen, then back to sddm.

Arch wiki solution involves systemd....so useless.
Ubuntu solutions use different commands and systemd.

Using newest nvidia-dkms from world repo.
On 2017 Lenovo 2-in-1. Mobile nvidia mx130/Intel i7

tried this recommendation from Plasma irc channel.
cat /sys/module/nvidia_drm/parameters/modeset
this displays "Y"    ....like  https://community.kde.org/Plasma/Wayland/Nvidia says. ...but doesn't work.

I am using a modified SDDM login called Slice_1.5  
...also switched to stock with same issue.

Any thoughts?

Well you're using nvidia so that's already iffy. Did you try using the shell command to launch Plasma Wayland directly in tty instead of using sddm?

Code: [Select]
XDG_SESSION_TYPE=wayland dbus-run-session startplasma-wayland

That is unfamiliar and scares me. My system is running smoothly otherwise and I hesitate to muck something up. I've been left high and dry...a lot.

If i do that is there a risk of black screen or something at reboot?
Will Plasma just start normally if rebooted?

Is there a decent guide page?

It's just the command to start Plasma Wayland instead of using a display manager. It's to make sure there's not any sddm weirdness going on and you'll actually see error output in the terminal if it fails. It's not going to permanently alter your config or anything.

  This gave me an error-wall and a "no skeleton found" message.

...also I have a 4k laptop and the default text setting is so tiny using tty1 I can barely read it. Would also appreciate an easy adjustment so I can see to type. (if such a thing is possible)

It would be helpful if you could direct the output to a file and post it somewhere so we can actually see the error messages.

It would be helpful if you could share how.  :)
No idea how to do that from tty....i can screenshot with phone.

iirc correctly there is a cat command...I'll look.

Found:      https://unix.stackexchange.com/questions/108493/easy-way-to-paste-command-line-output-to-paste-bin-services#108494
..and used :      $ ls / | nc paste.c-net.org 9999

.. all it copied was
https://paste.c-net.org/MexicoForensic

(I think because I exited with ctrl+Alt+esc, but i don't know another way)

No need to do that. Just redirect the output to a file.

Code: [Select]
XDG_SESSION_TYPE=wayland dbus-run-session startplasma-wayland &> out.log

Copy the file and paste the contents to a pastebin or something somewhere.

"cannot open display" is the main issue here. I'm going to just guess it's probably a driver issue at this point. Nvidia is allegedly supposed to work with wayland these days, but who knows.
