I am on a fresh install of Ubuntu 16.04 booted with bios. dlm.service refuses to start.

systemctl status dlm.service gives me:

● dlm.service - DisplayLink Manager Service
Loaded: loaded (/lib/systemd/system/dlm.service; enabled; vendor preset: enabled)
Active: activating (auto-restart) (Result: exit-code) since Sat 2016-12-31 13:57:00 EST; 1s ago

If there is any more information that would be useful, let me know.

my guess is evdi drive didn't install properly. Have you tried uninstall, install, and reboot?

you may be able to manually remove and reinstall evdi using the following commands:
sudo dkms remove evdi/1.2.65 --all
sudo dkms add evdi/1.2.65
sudo dkms build evdi/1.2.65
sudo dkms install evdi/1.2.65
reboot

report any error messages that pop, but this should work.

@yesennes just yesterday I witnessed install on fresh install of Ubuntu 16.04 with 4.8 kernel from 16.10. Everything worked out just fine and dlm.service starts fine.

Have you tried uninstall/install/reboot as @glindner suggested?

You need to have UEFI disabled, please see this issue for more info.

This workaround worked for me on Ubuntu 18.04 and DisplayLink driver v4.4

adnan hodzic fix

To fix, add an install section to /lib/systemd/system/dlm.service
