Ubuntu 19.04 and DisplayLink Driver
 
Has anyone tried it yet?

retrodaredevil 04-20-2019 06:45 PM

Yeah. After upgrading from 18.04 to 18.10 to 19.04 DisplayLink 4.4 wouldn't work so I tried installing 5.1. While installing, my computer froze except for my mouse. I had to power it off. The first time I powered it off, it was fine. The second time my computer booted into emergency mode. I got out of emergency mode by uninstalling it and rebooting. I believe the reason it's not working is because of how the kernel was upgraded.

If you want to keep a working Displaylink, upgrading probably isn't the best option.

If anyone knows when to expect a working driver for 19.04, some information would be awesome to know.

I just tried to bring up displaylink with 19.04 and did not succeed. I connect my monitor to the laptop through a D1000 -- something that is probably not an issue. I will try again after work.

retrodaredevil 04-22-2019 10:43 PM

So actually, after trying again, it worked. In general, it does seem a little buggy as my plasmashell crashed after rebooting and unlike installs on 18.04 I had to reboot to get the monitors to work at all. I don't really know why it works now. Last time it froze my computer on "Installing EVDI kernel module to kernel tree". This time it did the same thing, but after 10 seconds it completed.

Hopefully there will be a new update released that's tested and actually meant for 19.04, but if you're lucky, 5.1 does work. Sometimes.

Disclaimer: I did run a "sudo apt update && sudo apt dist-upgrade -y" today so it's possible that's the reason it works now.

5.1 doesn't work for me

taranovich 04-24-2019 07:26 AM

guys, you can try to install this driver - https://github.com/AdnanHodzic/displaylink-debian
it works for my 19.04 disco

Ubuntu 18.04.2 LTS and dock Dell D6000... have same problem, more frequent if I use Firefox

retrodaredevil 04-25-2019 09:14 PM

When I installed the driver at https://github.com/AdnanHodzic/displaylink-debian I didn't notice any differences from just installing 5.1 by itself.

ESSEDIA 04-29-2019 02:21 PM

Using suggest diplaylink-debian I have same problem that official... monitor goes randomly to blank screen and I disconnect and reconnect my D6000...

On my Ubuntu 19.04 laptop running kernel v5.0.0, is installed v5.1 from GitHub. Right after installing, my second monitor woke up and display its screen. I could use it without an issue. However, after installing it my laptop does not boot anymore. Through CTRL-ALT-F4 I was able to access a shell and remove the driver, after which my laptop booted as usual. SIgh.

Here you can find possible solution:

This works for me, try it!
Good luck!

Black screen
 
I'm using 19.04 via Pop!_OS. There does seem to be an issue with this but, during boot up press the F2 key and you'll see that it gets stuck on a startup task, if you leave it for about 5 mins you'll eventually see that it kind of hangs, at this point press CTRL + ALT + F2 and then CTRL + ALT + F1 and the Gnome GDM will load just fine.

Crashing of DisplayLink Driver when heavily using the network if
 
1 Attachment(s)
I'm finding that when duplicity kicks in in the mornings (backup is sent to network attached storage) that my screens freeze and the network connection dies.

I'm using a Startech.com DK30A2DH with dual 4K monitors and a couple of USB devices (keyboard, mouse headphones) but you'll be able to see all of this from the attached Support Tool log output attached to this post.

EJB 05-23-2019 09:27 AM

Thank you, @ESSEDIA, for your pointer. I tried many things from that site, and other stuff inspired by that site. Nothing worked.

I decided to do a clean 19.04 install on my Dell G5 5587, with D3100 docking station. The first thing I did, after the clean install was done, was to install the DisplayLink driver v5.1.26. And, guess what, it now works like a charm.

retrodaredevil 05-26-2019 01:00 PM

A while ago I got display link to install, and it works perfectly for the most part, except that one of my monitors is unusable. I'm running Kubuntu and my AOC monitor looks like this:

I can confirm that using DisplayLink driver v5.1.26 works (almost), on Ubuntu 19.04 (kernel 5.0.0-16-generic).

I can get two monitors to work with display port additionally to the laptop.

However, I'm experiencing random system freezes. Randomly, the whole system just stops, I can't see if there is any relation with what I'm doing. The only way to get the system back is a hard shutdown.

Any ideas on how to diagnose this?

For me, I would see the DisplayLink connected screens freeze and then I would unplug via usb and plug back in again, and then I'd have to run an alias which I've created from ARandR to fix my screen layout.

What I've found is that this always happend earlier in the day and it was happening when the network was very busy (backups being uploaded to the NAS). Since I've switched to plugging in the network cable directly into my machine that has resolved this issue for me. I don't particularly use the USB ports on my device, but I suspect heavy USB port usage could also have a similar impact.

In my case, when the screen freezes there is no coming back but a hard shutdown. Unplugging the dock doesn't do anything. The laptop's screen is still frozen, and there is no way to see if the inputs are coming through. I checked the logs, but I can't identify anything related to the displaylink since I don't know what to look for. :confused:

Can you
Code:

Alt+F2
then type 'r' and hit enter? You can't see it but this will refresh GDM for you (That's if you're using that desktop manager)
If that does nothing can you
Code:

Ctrl+F2
into a console? Then you might be able reload your display manager (although this will kill your current session) so I think that you can reload the DisplayLink service itself first with something like
Code:

sudo service displaylink-driver restart
.

I've found that sometimes the display manager would have issues with not displaying onto my internal screen (it would still act as if the display was disabled - as I used to have my laptop lid closed whilst using the other monitors.) There may be something in the
Code:

/var/log/syslog
.

Thumbs up for the latest release from me
 
I can confirm that my issue on startup where it looked like my machine was frozen has gone with the latest release and has been fine since release day (now my machine boots just as I would expect it to, without the ~5min delay in startup and the requirement to do the CTRL+F2, CTRL+F1 dance to get the GDM screen to appear.)

Let's hope that it continues to work with the 19.10 release later this year (I tend to do day 1 updates, and sometimes I jump onto the beta/RC releases if I have a particularly annoying issue which is fixed in the newer version.)

Version 5.2 https://www.displaylink.com/downloads/ubuntu works for me with Ubuntu 19.04 and Intel UHD Graphics 615 on Dell XPS 13 9365 except the "Power delivery" with "i-tec USB 3.0 / USB-C / Thunderbolt 3 Dual Display Docking Station" https://i-tec.cz/en/produkt/cadual4kdock-2/ .

The notebook is charging neither via USB-C nor Thunderbolt both in Ubuntu and Windows. Does this work for anybody? Do you have any suggestions I could try?

There is a workaround. The charging works when the docking station is connected to the notebook via "i-tec USB-C Travel Adapter PD/Data" https://i-tec.cz/en/produkt/c31dtpdhub3-2/

I initially had some trouble, but now have Display Link working, with 2 monitors (Targus USB dock).

Initially didn't work at all. Running Ubuntu 19.10, now with generic kernel 5.3.18-050318-generic.

I moved to generic kernel to get around the lockdown disable of hibernate (although I haven't got that working yet); originally had kernel 5.5, but got errors messages trying to install the Display Link drivers. Went back to 5.3 (same major series as 19.10 signed kernel).

Could install, but still not working. The devices showed up in lsusb when the USB was plugged in, but not in xrandr.

Checking the known issues: https://support.displaylink.com/know...ubuntu-support

* Wayland is not supported, on the sign in screen there is a drop down to select Ubuntu vs Ubuntu on Wayland, which was selected. Changed back to just Ubuntu. The screens now appeared in device manager, but were black.

* Proprietary Nvidia drivers not supported. I was using Nvidia 435. Changed back to Nouveau, rebooted, and now have dock with two external screens, plus the laptop screen, working.

Also in the notes, Secure Boot is not directly supported, although you can sign the drivers yourself. I had already changed this, trying to get hibernate working (i.e. remove lockdown). I still have Secure Boot turned on in the BIOS, so I can dual boot into Windows (with Bitlocker), and am using the signed Grub bootloader, but have turned off security in Grub, to be able to load the unsigned generic kernel.

(When booting, Grub shows the message "unsecure mode")

So, read the documentation, check the known issues, and hopefully you can get it working!
