I noticed this might be yet another DisplayLink outcry - but I thought I give it a go anyway. So the usual story - I have got a DisplayLink adaptor Kensington USB3.0 Video Adapter, and doesn't look like is ever going to work.

It is reorganised when I plug it in.

#uname -r

# dmesg

[52049.856134] usb 2-2: new high-speed USB device number 8 using ehci-pci

I have blacklisted udl in /etc/modprobe.d/blacklist-custom.conf and removed removed udlfb from /etc/modprobe.d/blacklist-framebuffer.conf.

I have also manually loaded the udlfb driver.

# modprobe udlfb

[52418.187053] usbcore: registered new interface driver udlfb

Ok so basically I am not moving forward with this - because when I do;

# ls /dev | grep fb

fb0 is the only device block found - which indicates to me that udlfb is not detecting the device. udevadm info on fb0 reveals - it is the main laptop screen.

# udevadm info -a -p $(udevadm info -q path -n /dev/fb0)

 looking at device '/devices/pci0000:00/0000:00:01.0/0000:01:00.0/graphics/fb0':

I currently have 1 provider and that is the main screeen.

# xrandr --listproviders

Providers: number : 1
Provider 0: id: 0x65 cap: 0x1, Source Output crtcs: 2 outputs: 4 associated providers: 0 name:nouveau

Digging through /sys/class/graphicsI noticed fbcon with this settings:

  looking at device '/devices/virtual/graphics/fbcon':

Let me also mentioned that I have tried udl with udlfb blacklisted with no joy neither.

OK so long story short - Is anyone managed to get similar DisplayLink USB 3.0 Adaptor working with Ubuntu 14.04 LTS or similar?


Update August 2015

3 years after releasing the chipset, Displaylink has released beta versions of a driver to support the DL3XXX chip generation under Ubuntu 14.04. I leave the following content as original reply to the questions.

Please see:

Old information below

The USB3.0 Displaylink devices do NOT support Linux

In particular, this includes the Displaylink DL3XXX-generation and newer.

Displaylink has no intention to make a driver in foreseeable future. See this thread.

Wim of Displaylink wrote on 08-17-2012:

We don't have any ETAs at the moment, and still looking at the best path to do this. One issue is that the DL-3000 supports content protection and we need to ensure this remains secure under an open source environment.

This was also discussed in this answer. More related questions here: this

EDIT: July 2015

It seems that USB3.0 support for Linux might come in Q3 2015, as announced here (Thanks NecLimDul)


Displaylink just released a Linux driver for USB 3 devices: http://www.displaylink.com/downloads/ubuntu.php

I tested it under Ubuntu 15.04 with Dell's USB3-Ethernet/VGA/HDMI adapter and it kind of worked, although the recognized display resolution was too low. Also, I have to re-run the installation script after every reboot

  • I have installed it - but still no joy. Can't even see activity of it in dmesg. – Bitmap Aug 6 '15 at 11:06
  • It works for me. with Ubuntu 14.04 after upgrading the kernel (it is 3.16 now). I don't need to rerun the installation script. – Reinier Post Aug 28 '15 at 14:17
  • With compiz, it forgets to update the screen after a keystroke, at least on my computer, which makes the displays pretty hard to work with. Solution: start up with metacity instead (GNOME Metacity Flashback in the Ubuntu Unity launcher). – Reinier Post Oct 7 '15 at 11:07
  • I installed the driver on ubuntu 14.04 with kernel version 3.19 but still hdmi does not work for me on Dell XPS 13 – curious Apr 21 '16 at 16:09
