Second display on UD-3900 won’t work as “plug-n-play”, but rather only works after reboot (or fresh boot). Can I change setting? Using Ubuntu 16.04.4 LTS Intel HD620 GT2 (Kaby Lake).
Here’s the fix; you need to force Ubuntu to use the INTEL driver as opposed to the modesetting, which is the default for Debian/Ubuntu.
$ sudo apt install xserver-xorg-intel-hwe-16.04
$ sudo gedit /usr/share/X11/xorg.conf.d/20-displaylink.conf
Once the file opens; insert this text into the open (empty) file:
Section “Device”
Identifier “Intel Graphics”
Driver “intel”
EndSection
Save the file.
Close the file.
Reboot.
Hi Andor,
Thanks for reaching out to us and providing the solution you found!
We support Linux on our products whenever possible, unfortunately USB graphics support in Linux has not reached the point we can recommend or support these products on Linux systems. This is mainly due to the vast many factors such as graphics drivers, desktop environments, and windows managers, to name a few, that can reduce performance problems or prevent the USB indirect graphics from working correctly.
DisplayLink, the manufacturer of the hardware and software used in our docking stations, does offer support for Linux hosts. Here is a link to their troubleshooting page ( https://support.displaylink.com/knowl… ), and how to report issues to DisplayLink directly here ( https://support.displaylink.com/knowl… ).
I also wanted to provide the link to the specific support article you provided in your email ( https://support.displaylink.com/know
ledgebase/articles/1181623-displaylink-ubuntu-driver-after-recent-x-
upgrades ).
Thank you again, we will be closing this thread since the issue is resolved.
