Make the Linux driver open source and get it into the kernel
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 bought a thinkpad docker usb c with 2 hdmi and I am very disapointend.
Its a same most of people buying this item usually they do not use windows.
Still doesn' t work well on Fedora 31 I have some many troubles to do it work. I have tried on ubuntu ass well and there just work on gonome but not on wayland it is imposible to rescale 125% or 150% . Only works well on windows 10. I am going to return to Amazon. If you do not offer a good support to linux I would not buy anymore to my bussines -

I've written a patch for 5.2.14 dkms module for Linux 5.4.x compatibility: https://gist.github.com/alllexx88/1aebabd49da990089a489cb4f5c94698
You can apply it as follows:wget -q -O- https://gist.githubusercontent.com/alllexx88/1aebabd49da990089a489cb4f5c94698/raw/c0856b2ab2d15f534686f8bbaa8ee48e8d93b4d6/DisplayLink-5.2.14-Linux-5.4.patch | sudo patch -p1 -d /usr/src/evdi-5.2.14
Then make sure your compiler (/usr/bin/cc) matches the version used to build your kernel (e.g., atm for kernel 5.4.x installed on Ubuntu using ukuu it has to be 9.2.1) and build+install the dkms module:
sudo dkms install evdi/5.2.14 -

Have a lot of issues with this.
Would be great if it was just integrated with Linux kernel hence not requiring DKMS crap which make kernel hard to boot in secure boot environment.

Still (18. Dec. '19) no support for Kernel 5.4.x !!!!!

ugh still poor linux support , good product crap compatibility because of lack of working drivers

It's a shame. Nothing less. In our days and age to have to manually download a
driver, broken moreover, and unable to follow modern kernels developement. This
is unacceptable. -

It's not just about Linux.
There are other OpenSource UNIX like operating out there which also would like to implement an USB3 udl driver which gets you potential new customers.
OpenBSD e.g. has an USB2 udl driver, and we also would like to implement the USB3 one.Why not doing it as suggested by Puchuu Punya and make a compression blob and release the driver itself as open source?
Would appreciate a feedback from you, private or public - Thanks.

I been using Linux desktop since 1999 and I cannot believe that today I still have to deal with such a product like this.
I started in a new company, installed Linux and plugged in the Type-C dock that I was provided just to learn that there is a company named DisplayLink that spreads this proprietary technology all over the place.
After doing some research on how to get this dock to light up on my Fedora Laptop, I actually figured I need something else, an alternative to this DisplayLink crap.I use Fedora like many other developers and see that only Ubuntu is supported.
Can anyone recommend something that simply works on Linux? (Type-C x 2 Monitors and charge?)Thanks

Has anyone figured out on how to flatpack or snap pack display link drivers along with dependencies? Using solus 4.0 here and a newbie.

This would be a great idea! By making it open source, the overall experience will be better on Linux because you won't have to worry about getting the correct version anymore. Whatever distro you're running will have the version of Display Link you need ready to install a command away. This would also allow support for a newer distro like Ubuntu 19.04 to be available sooner.

It's great that DisplayLink shows support for GNU/Linux. Now, if they would release the source code as libre software that would be awesome. And make it easy or "automatic" to install. Awesome!
GPL v3 is a good license for driver software. (It's for hardware; that's exactly why Richard Stallman started GNU.)

Puchuu Punya commented
> Agreed. If the compression technology is too proprietary to be released, then make 2 separate modules, one proprietary to load the compression algorithms, one open source so that kernel developers can easily port the module and update with each new kernel, while the compression algorithm remains closed source and proprietary. That way is best of both worlds.
It is 100% true. You can make a pure compression blob with simple input-output interface and nobody will touch your patents, you can keep it forever.

Do not forget that there are some bad countries like post USSR. Here we have no laws, we can make reverse engineering of your software. Unfortunately mobile monitors is not so popular and nobody wants to do reverse engineering today. But I have to warn you about it.

As the OPs post was in 2017 and this still hasn't been fixed 2 years later, it seems DisplayLink does not respect the Linux community. I'm currently stuck with a d3100 which doesn't even work with USB support. It works only as a passthrough for network connections. If my laptop doesn't have an ethernet port AND had wifi not working, THEN it might be useful. As is, I have absolutely no use for this POS as none of the features I purchased it for will work. I'm currently running Arch proper with the newest available driver installed. I've just gone through every post on the DisplayLink forums and am seeing absolutely no response anywhere from this company.
I've had the device for a few months or I'd send it back for a full refund and look for a replacement. -

Please, open up your crappy drivers, if you can't fix your own s*it and make it stable. Let's users do your job properly.

funny that no answer from DL in this
thats because they now we are right best way is to let it be opensource so more people can fix the issues that are in the driver all the time -

Is this request being ignored by DisplayLink? This is top 4! Why do other requests with a way lower ranking have already gotten feedback from DisplayLink?

I've just installed the driver on Ubuntu 18.04 , running on an xps 13 9360 with 4k panel, connected to a D6000 dell docking station. If I set the scaling to 100% on my dell 2k monitor, it sets the scaling back to 100% on the laptop, making it unreadable, and if I put the scaling back to 200% on the laptop, it alters the Dell monitor. They are supposed to work separately. Also, the night light mode is working on the laptop, but not on the separate monitor. This basically makes it COMPLETELY UNUSABLE on my Linux installation. Yet it all works fine on windows 10.
Then there is the issue of having to sign the drivers (what an epic pain) or turn off secure boot!! I mean really?? Please make the driver open source, so it can be integrated properly with Linux distributions, as the open comment suggested. As it stands now the support is atrocious. Ubuntu 18.04 works flawlessly with the 9360 btw, if anyone is thinking of trying it :-) -

Indeed. The people most likely to have multiple monitors attached to a laptop are usually Engineers and Software Developers. Guess what these types of individuals use as an OS? ...Linux. Get with the times displaylink...
