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:

The switch b was selected with the argument 4
The switch c was... (3 Replies)

device::usb::bus
Device::USB::Bus(3pm) User Contributed Perl Documentation Device::USB::Bus(3pm)NAME
Device::USB::Bus - Use libusb to access USB devices.
VERSION
Version 0.12
SYNOPSIS
This class encapsulates the USB bus structure and provides methods for retrieving data from it. This class is not meant to be used alone,
it is part of the Device::USB package.
Device:USB:LibUSB provides a Perl wrapper around the libusb library. This supports Perl code controlling and accessing USB devices.
use Device::USB;
my $usb = Device::USB->new();
foreach my $bus ($usb->list_busses())
{
print $bus->dirname(), ":
";
foreach my $dev ($bus->devices())
{
print " ", $dev->filename(), "
";
}
}
DESCRIPTION
This module provides a Perl interface to the bus structures returned by the libusb library. This library supports a read-only interface to
the data libusb returns about a USB bus.
FUNCTIONS
dirname
Return the directory name associated with this bus.
location
Return the location value associated with this bus.
devices
In array context, it returns a list of Device::USB::Device objects representing all of the devices on this bus. In scalar context, it
returns a reference to that array.
find_device_if
Find a particular USB device based on the supplied predicate coderef. If more than one device would satisfy the predicate, the first
one found is returned.
pred
the predicate used to select a device
returns a device reference or undef if none was found.
list_devices_if This method provides a flexible interface for finding devices. It takes a single coderef parameter that is used to test
each discovered device. If the coderef returns a true value, the device is returned in the list of matching devices, otherwise it is not.
pred
coderef to test devices.
For example,
my @devices = $bus->list_devices_if(
sub { Device::USB::CLASS_HUB == $_->bDeviceClass() }
);
Returns all USB hubs found on this bus. The device to test is available to the coderef in the $_ variable for simplicity.
DIAGNOSTICS
This is an explanation of the diagnostic and error messages this module can generate.
DEPENDENCIES
This module depends on the Carp and Device::USB, as well as the strict and warnings pragmas. Obviously, libusb must be available since that
is the entire reason for the module's existence.
