Can't make KDE/Wayland stick

[football1024]

I want to have my session log into KDE/Wayland. It currently logs into KDE/X11. Here’s what I do:

1. log out of a my session
2. select ‘Plasma/Wayland’ from the selector on the login screen
3. login
4. get the Wayland session
5. reboot
6. get the X11 session

Any idea why my Wayland choice doesn’t survive a reboot? I had a similar experience when I installed Gnome. I had to uninstall it just to get back to KDE being the default.

Which display manager are you using? That might help others advise further.

/usr/sbin/update-alternatives --query default-displaymanager

Thanks for the suggestion. Here’s what I get:

alan@localhost:~> /usr/sbin/update-alternatives --query default-displaymanager
Name: default-displaymanager
Link: /usr/lib/X11/displaymanagers/default-displaymanager
Status: auto
Best: /usr/lib/X11/displaymanagers/sddm
Value: /usr/lib/X11/displaymanagers/sddm

Alternative: /usr/lib/X11/displaymanagers/console
Priority: 5

Alternative: /usr/lib/X11/displaymanagers/gdm
Priority: 25

Alternative: /usr/lib/X11/displaymanagers/sddm
Priority: 25

Alternative: /usr/lib/X11/displaymanagers/xdm
Priority: 10
alan@localhost:~> 

That reminded me of something I tried when trying to un-default Gnome. It had no effect back then either, but this what I get now (might be irrelevant, since X11/Wayland doesn’t seem to be involved):

alan@localhost:~> sudo update-alternatives --config default-xsession.desktop
[sudo] password for root: 
There are 3 choices for the alternative default-xsession.desktop (providing /usr/share/xsessions/default.desktop).

  Selection    Path                                        Priority   Status
------------------------------------------------------------
  0            /usr/share/xsessions/plasma6.desktop         25        auto mode
  1            /usr/share/xsessions/gnome.desktop           25        manual mode
  2            /usr/share/xsessions/icewm-session.desktop   15        manual mode
* 3            /usr/share/xsessions/plasma6.desktop         25        manual mode

Default plasma session remained X11 after upgrade

When I installed openSUSE Tumbleweed on my new laptop a year back I had chosen to automatically login to my user account (mostly because I chose encryption). At any rate, after the Plasma 6 update I was expecting to be on Wayland, but the “Graphics Platform” remained X11 (which was more buggy for me). I haven’t had much interaction with SDDM previously, so I only figured out I had to log out and pick Plasma-Wayland as session more or less by accident from reading random comments about the upgra…

Here you go. This should fix it.

Harsh. But that did fix it. BTW, that had how to make Wayland stick, so here’s what I use when I want X11 to stick:

/etc/sddm.conf.d/session.conf

[Autologin]

# The following gives KDE Plasma 6 with Wayland
#Session=plasmawayland.desktop

# The following gives KDE Plasma 6 with X11
Session=plasma6.desktop

For the record, Andrei, I always exhaust search possibilities before creating any posts for help. Which is why I hardly ever create those kind of posts. I also search for answers when I decide to help someone else here, unless I already have solved it for myself. So, yes, somebody does …
