#lsmod | grep udl

Into your dmesg, there is always a problem with the display manager service :

[    9.553262] systemd[1]: Cannot add dependency job for unit display-manager.service, ignoring: Unit display-manager.service failed to load: No such file or directory.

Since it's not running, your displaylink service will not run correctly...
You can try to use lighDM or another DM to test before resolve your KDE problem...
What have you fond to reinstall KDE ?
