I suggest you...

Not working on ubuntu 16.04

After I upgraded to 16.04 LTS, I could not use my DisplayLinks graphics/ethernet adapter for graphics (ethernet works fine). I recently installed the newest driver (1.2.65) but I get this error:

Warning: 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 run journalctl as suggested by the error message and here is what I get:

26 16:27:28 myhost systemd[1]: Starting DisplayLink Manager Service...

Any ideas?
