I’d like to easily test window decoration in Wayland, which requires restarting
kwin_wayland. Unfortunately we can’t do that as
kwin_wayland is the login session.
The KDE Neon Developer/Unstable ISO currently boots into a default user by default, skipping the SDDM login screen. We can’t logout, or switch user as it will automatically login to the default user again.
I figured there’s probably a SDDM config file to control which Desktop Environment a user logs into, and I was right. The Arch wiki documented the autologin configuration, though for Neon (an Ubuntu derivative), the config file was at
Open it up with
sudoedit /etc/sddm.conf (default editor is
nano) to find:
ls /usr/share/wayland-sessions finds
plasmawayland.desktop. So just edit
Session=plasmawayland.desktop and save it.
Finally logout of the user. It should automatically relog into a wayland session.
