Wayland boot loop on KDE Plasma

Desktop Environments Plasma
1

Can not boot into Wayland unless I drop down to tty3 and run systemctl restart sddm.
Fresh install on different computers all seem to have the same problem and restarting sddm in tty seems to be a work around for now. Hoping one of you good folks here can lead me down the path to success.

What about ltskernel? Same issue?
I see you are using a fresh installation. I already had problems with Plasmoids under Wayland which were not updated.

I’m sure that I tried the lts kernel but did a fresh install after trying everything including the kitchen sink, just installed the lts kernel and the problem remains.
Many thanks for your assistance.

Able to boot into Wayland now without having to drop into tty by creating 10-wayland.conf

/etc/sddm.conf.d/10-wayland.conf

[General]
DisplayServer=wayland
GreeterEnvironment=QT_WAYLAND_SHELL_INTEGRATION=layer-shell

Will not mark this as a solution yet as I may change things around a little.

Are you by any chance, using autologin into plasma-wayland session?

If adding the following config works:

/etc/sddm.conf.d/10-wayland.conf
----

[General]
DisplayServer=wayland
GreeterEnvironment=QT_WAYLAND_SHELL_INTEGRATION=layer-shell

[Wayland]
CompositorCommand=kwin_wayland --drm --no-lockscreen --no-global-shortcuts --locale1

Then, its most probably because sddm runs in x11, and therefore wayland session is launched in separate tty and the switch between ttys is not made successfully each time.

6

Thanks for the reply, no I’m not using autologin. The only lines in 10-wayland.conf are

7

Also add the following as a parameter to CompositorCommand into the SDDM config /etc/sddm.conf.d/10-wayland.conf:

[Wayland]
CompositorCommand=kwin_wayland --drm --no-lockscreen --no-global-shortcuts --locale1

I will certainly give it a try, post back shortly.

@ainz I will mark your post as the solution as they both work, yours is likely the better way.
Many Thanks !

PS you can work on my truck any time. :rofl:
