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?
20.04 LTS now also supported

Why not just ask the code to be included in the next linux kernel?.
There is a good rpm creator that downloads your driver and creates a fedora RPM package but my distro does not support systemd scriplets.
Unfortunately I don't know how to modify the .specs file.

Come on guys!!!

I was able to get working by following:
https://support.displaylink.com/knowledgebase/articles/1181623-displaylink-ubuntu-driver-after-recent-x-upgrades
as mentioned by Andor and finally following Eder's instructions -

Try the PADOKA PPA for the stable Intel drivers. Also, you'll need to disable Page Flip in your xorg.conf file.

I am using Ubuntu 17.10, and the steps to get it working are:
- Install DKMS package;
- Remove the cable from usb port;
- Run the installation;
- Reboot and disable security boot on motherboard settings;
- Reconnect the cable;
- Reboot;Everything is just working fine after this.

Nearly the same error message as above, but substantially the same. I do not believe this is an error from DisplayLink. In my case, it was because of my default BIOS security settings.
My UEFI Bios Secure boot setting was active. I believe it was preventing all third party drivers, DisplayLink included, from installing.From here: https://askubuntu.com/questions/762254/why-do-i-get-required-key-not-available-when-install-3rd-party-kernel-modules (The post by Pilot6)
It shows two ways to disable it. For my Ubuntu 16.04 LTS, I used:
sudo apt install mokutil
sudo mokutil --disable-validation
..It will ask you to set up a password of at least 8 chars. Write it down. When you reboot it will ask for random chars within that password string.. char 2, char 7, etc. You will then be able to disable secure boot.
Everything came up fine after this.

Disconnect the usb port to the dock station and rerun the driver installation. That worked for me.

Umm, ok, this was last October, and it's now almost February. Buehler? ... Anyone? ...
