I am trying to install WavLink's docking station (WL-UG93DK3) using DisplayLink's instructions, as directed from the WavLink website. I'm following the instructions perfectly, and when running the .run file, the terminal throws this error:

Warning: The unit file, source configuration file or drop-ins of dlm.service changed on disk. Run 'systemctl daemon-reload' to reload units.
Job for dlm.service failed because the control process exited with error code.
See "systemctl status dlm.service" and "journalctl -xe" for details.

I installed this fix, but to no avail. Although the drivers are installed, I still don't have my multiple monitor functional on Ubuntu. It works fine on the Windows side, so I know it's not a hardware issue.

Driver verification:

$ sudo displaylink-installer

I currently have only my keyboard and external monitor plugged into the dock, but my Logitech mouse isn't, however the mouse and keybard are in Bus 002, and the monitor isn't recognized.

The FAQs link doesn't address this plethora of problems. What did I do wrong?

Computer stuff: HP Envy x360 laptop, dual-booting Win10x64 and 18.04x64, AMD® FX-9800P Radeon r7 (12 core), 8GB RAM

Thank you in advance. -K
