driver 4.2 and DIAMOND BVU5500H USB3.0 to HDMI don't work on ubuntu 16.04LTS

[trucscreen]

Hello,

I try to connect this monitor samsung syncmaster bx2240 lcd full hd 1080p 21.5'' through a DVI to HDMI adapter to this device https://www.diamondmm.com/product/bv...splay-adapter/.

Then I follow those instructions : https://support.displaylink.com/know...ware-on-ubuntu

But I end up with this in the terminal :

$ sudo ./displaylink-driver-4.2.29.run

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.

and so I don't have the last line displayed on the tutorial which is

Starting DLM upstart job

...

What should I do please?

Also here is my config :

$ lspci -vnn | grep -A 12 '\''[030[02]\]' | grep -Ei "lay|kernel"

I'm gonna take a few guesses on what you're supposed to do since I feel like I've gotten an error like this a while ago. I'm going to guess you tried running

systemctl daemon-reload

If not try that first. If not try restarting your computer then try running

systemctl start dlm

then you can try

systemctl status dlm

to see if it actually worked.
If none of those worked, do

displaylink-installer uninstall

then restart, and try to run the installer again. I found that whenver you uninstall it, you have to restart if you want to reinstall it. However, whenever you install it, if it runs correctly, you shouldn't have to restart your computer.

Of course, you'll have to use sudo for most of those commands.
