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.
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 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.
