So up until a little while ago, Dolphin/Kate/etc… KDE programs were running fine in a graphical interface via wslg on my SUSE-TW Windows Subsystem Linux. However, it now appears KDE applications will only run with systemd enabled for WSL. I typically don’t have systemd enabled because the default mount point of /mnt/ is used instead of the override in wsl.config automount root option of /run/media/user, as SUSE typically uses.
So I can either have KDE working with systemd with messed up mount points, or I can have no KDE applications without systemd. Other GUI applications seem fine and just KDE is affected.
