DisplayLink USB 3.0 Not working on Ubuntu 14.04LTS

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
3.13.0-35-generic

# dmesg

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':
    KERNEL=="fb0"
    SUBSYSTEM=="graphics"
    DRIVER==""
    ATTR{pan}=="0,0"
    ATTR{name}=="nouveaufb"
    ATTR{mode}==""
    ATTR{console}==""
    ATTR{blank}==""
    ATTR{modes}=="U:1440x900p-0"
    ATTR{state}=="0"
    ATTR{bits_per_pixel}=="32"
    ATTR{cursor}==""
    ATTR{rotate}=="0"
    ATTR{stride}=="7680"
    ATTR{virtual_size}=="1920,1080"

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':
    KERNEL=="fbcon"
    SUBSYSTEM=="graphics"
    DRIVER==""
    ATTR{cursor_blink}=="0"
    ATTR{rotate}=="0"

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:

DisplayLink Ubuntu Driver Download and
How to install DisplayLink software on Ubuntu on the DisplayLink website

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
