Ubuntu 16.04 doesn't detect my second monitor

I have Ubuntu 16.04 (dual boot with Windows 10) and a HP Spectre x360 laptop.

I have recently bought a Dell Ultrasharp U2515H monitor, which I connect via a Dell docking station.

When I plug the docking station to my laptop on Windows, both monitors are detected and everything works fine.

The monitor connect to the docking station using a DP cable, and then a SuperSpeed USB 3.0 Type A to B Cable connects the docking station to my laptop.

When I try with Ubuntu, it seems that the second monitor is not detected even when I click "Detect Displays" - I just see my one built in monitor. I think I correctly downloaded the drivers for the Dell docking station, because the external mouse, keyboard and ethernet connection all seem to be working correctly.

Any help to get Ubuntu to detect my second monitor would be much appreciated. The results of lsusb are posted below:

lsusb is not going to list your monitor, or even your video card, only usb things hence lsusb. Try lspci.

What's your video chipset, and what video driver are you using?

Laptop hardware is the worst, everything is customized in a manner plug-and-play often can't detect. The manufacturer's official Windows drivers come pre-tweaked for it, anything else may take tweaking to be told what features the hardware has.

Wait, your docking station connects with USB? What docking station is this?

It's probably acting as a USB hub, hence recognizing the USB mice etc, but those 'Dell Computer Corp' devices aren't necessarily recognized.

D3100 uses a DisplayLink chip, and DisplayLink has a page specifically for Ubuntu:

As I mentioned, I believe that I have already downloaded and installed the DisplayLink driver for Ubuntu. Perhaps the outputs that I showed say otherwise? I'm not sure how to test.
