If the DisplayLink driver existed in the kernel, it would be SO much easier for the users to get it working. In my role as Chief Digital Officer for a large company (of 8000 people), I would probably have bought 500 of these devices IF the driver were just upstream (you know, how Linux devices normally "just work" without the aggro common in the Windows world). However, the annoyance of a manual driver install, especially when it's broken on updates to newer kernels, is just something I wouldn't want to invest in. Please consider that proprietary drivers are serious impediment to sales, and just work with a willing community upstream.

I had version 1.1.62 of the Ubuntu driver installed. When I tried to install the new driver, I got errors saying the EVDI module was running and I needed to reboot to continue the installation. After reboot, I got the same error again.

After looking into the running DisplayLinkManager process, I ended up dropping into /usr/lib/displaylink and running the install script there with the uninstall option:

me@mine:/usr/lib/displaylink$ sudo ./displaylink-installer.sh uninstall
DisplayLink Linux Software 1.1.62 install script called: uninstall
Distribution discovered: Ubuntu 16.04.2 LTS
Uninstalling
Removing EVDI from kernel tree, DKMS, and removing sources.
Stopping DLM systemd service
Removed symlink /etc/systemd/system/graphical.target.wants/displaylink.service.
Removing suspend-resume hooks
Removing udev rule
Removing Core folder

Uninstallation steps complete.
Please note that the evdi kernel module is still in the memory.
A reboot is required to fully complete the uninstallation process.

This finally allowed me to go install the new driver after a reboot. Can you guys just add some upgrade logic into your installation script?

I have increased Mouse lag since the W10 Redstone / DisplayLink Driver 8.0 Update. I have a 3-screen Setup here. Surface Pro 3 + the DisplayLink USB Docking Station with 2 additional Screens. Working on those 2 external Screens got a bit tedious since the W10 Redstone / DisplayLink 8.0 Update. Maybe I´m too sensitive, but I feel enough mouse lag on the external Screens to slow down my daily work a bit. I´m using the DisplayLink Adapter since 2 years now and there were highs and lows regarding lag, but Version 7.9 on Windows 10 1511 was really good. Now with the new Windows / Driver Version (and the new Driver model?) it got worse.

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:

Any ideas?

It seems to me that many people are reporting instability issues for Ubuntu 16.10 using the latest 1.2.65 driver. Severe instabilities occur for certain types of hardware that was supported in Ubuntu 16.04.

I have a Dell XPS 13 (9343) and DL-3100. The screen keeps disappearing and re-appearing. It happens really randomly and sometimes many times per minute, other times it might be once per 20 minute. The displays go to black and everything crashes. It crashes often, but not always. This makes the applications stuck to that display crash as well. It is very poor performance (lag/hanging/high CPU usage) and not possible anything else than very low resolution. The poor performance and high CPU usage is a constant problem, but it gets worse right before and right after the crash (system almost hangs/freeze).

The setup worked flawlessly in Ubuntu 14.04 (no problems). This is also a "clean install" of Ubuntu 16.10. Hope you could fix this in the next release!
