I have Ubuntu 18.04.2 LTS and Linux Kernel 5.1.9, too.

My adapter (UGA-165) worked plug-and-play, however, the colors were distorted.

I then downloaded the 5.1 Displaylink drivers for Ubuntu and had exactly the same issues as you, and managed to install it, too, I just had to do one thing differently, Instead of:

- unzipped evdi-1.6.1.zip and copied evdi-1.6.1/module/* in /usr/src/evdi-5.1.26

I had to:

- extract evdi-1.6.1.zip
- cd into evdi.1.6.1/modules
- run tar -zcvf evdi-5.1.26.tar.gz .
- replace displaylink-driver-5.1.26/evdi-5.1.26.tar.gz with the one I've just created on the previous step, since the installer will extract and use that

The driver installed, but now, it's not recognizing the monitor anymore. The adapter just blinks twice and nothing happens.

I'll keep this updated if I manage to get it working.

-- Edit

I see that during the installer, it says:

Adding udev rule for DisplayLink DL-3xxx/4xxx/5xxx/6xxx devices

But I'm using UGA-165. I wonder if that's why it's not working?

-- Edit 2

Uninstalled displaylink-driver-5.1.26 and installed displaylink-driver-4.4.24 using the same techniques as above, but got the same results. Installer says:

Adding udev rule for DisplayLink DL-3xxx/5xxx devices

Wondering if I should do something else for the UGA-165
