Default Monitors aren't detected on Ubuntu 16.04

Hello,

I've a Dell D3000 docking station. I am running Ubuntu 16.04 and I tried the DisplayLink drivers 4.2.29 and the 4.4. The docking detects the keyboard and mouse but it doen't detect any monitors. I am trying to connect with both DVI port and the HDMI port but none of them are detected. Can anyone please help me to solve this issue?

I've Nvidia GTX 1070 Ti card connected to the system.

Linux kernel: Linux 4.4.0-31-generic #50-Ubuntu SMP Wed Jul 13 00:07:12 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

The secureboot is disabled in my bios.

When I see dmesg following messages I find regarding to evdi.
