I have a DisplayLink-based external USB monitor, which has both power and data over USB, and seems to work perfectly under Windows 7, but only can display a text console under Ubuntu 10.10, and that I can only use when I am actually switched to it. So the only Use I can have so far is to have some text-based monitoring or console that I can watch while working on the graphic display.

I know there are some development done for DisplayLink, but I never could get it to actually run properly.

Yes, I tried the detailed setup described in other posts, but they did not work, and instead crashed my X that I had to restore.

Merci :-)

Can you give us the name of your monitor? (manuf. and model) – Nathan Osman Oct 14 '10 at 21:14
Mine s the iMo USB Sub-Monitor, as sold at / The Model is actually the XT-7, as I can see on the CDROM. – jfmessier Oct 15 '10 at 17:53
Which laptop/computer and graphics card do you have? I have an HP dv7 4183cl, and am trying to setup a triple head using 1 displaylink monitor. – user12046 Mar 8 '11 at 22:17
I would like to add that only USB2 Displaylink devices are supported in Linux, but the newer USB3 devices are NOT supported. More info here:… – noleti Aug 29 '14 at 2:08

On Aug 3, 2015, Displaylink finally released the USB Monitor driver for Ubuntu.


I have an AOC usb monitor and Ubuntu 14.04. After installing the driver, my usb Monitor start working.

If the driver works for your monitor, please let other people know by posting it. Many people waiting for this driver. I've been waiting for 2 years. :-)

I've been waiting for four years now. Actually, the monitor is in some box somwehere in the home. But I will get the driver and see hw if works on my installation. I now use Ubuntu 15.04. Thanks for the link. – jfmessier Aug 19 '15 at 11:10
It works for me on Ubuntu 14.04 after installing a more recent kernel than the standard one (sudo apt-get install linux-generic-lts-utopic). In my case, the monitors themselves do not use USB, but I use a Dell or HP docking station / port replicator to which I connect them. With compiz, the displays are not updated after each keystroke (only upon the next one), which is really annoying. With metacity, this problem does not occur. – Reinier Post Oct 7 '15 at 11:14
@user1715991 would you kindly tell us exactly what's your AOC monitor? – igorsantos07 Nov 4 '15 at 15:25
Thank you so much (finally)! I can confirm this working with an HP NL571AA USB Graphics Adapter, Ubuntu 14.04.3 LTS 64-bit, and a HP 1955 19" (tertiary) monitor. I only had to switch from the binary NVIDIA drivers to the open source Nouveau ones to make it work. – Ingo Karkat Nov 5 '15 at 16:34

Maybe this get's you a little bit further:

General DisplayLinkAdapter-Information for Linux is available at

Also, if your primary graphics-adapter is from nvidia, you should read

Good Luck

Lots of useful links. Will take me some time to read it all and setup, but I htink I"m in the right way to get it working. – jfmessier Nov 6 '10 at 13:00
@jfmessier, did you get it working? – Thorbjørn Ravn Andersen Feb 27 '11 at 8:28
Not yet. All I can get so far is a graphical display, but then the other monitors are black, useless. I still have to merge the configuration files together. My existing xorg.conf file is empty, and if I put the config file for the DisplayLink, it disables everything. So I need to generate the xorg.conf file for my existing monitors and then figure out how to append the DisplayLink stuff in it. BTW: I now have an ATI-based dual-monitor display, while I used to only connect to the on-board Intel-based adapter. – jfmessier Mar 7 '11 at 19:52
I see it's been a while since this was updated. Would you mind telling me whether DisplayLink USB monitors work well for you with current software? – Ken Kinder Jun 4 '12 at 18:55
@Ken, they work out of the box only on Linux 3.9 and later which ships in Saucy Salamander. – Shnatsel Aug 29 '13 at 0:39

Here's an easy way to test if your DisplayLink device is operable at a low level, under Linux. If you plug in the device and get a green screen, you're ready for the next step.

First convert a bitmap to the size of your screen, then convert it to 16 bit RGB color. Then copy to the framebuffer for the device:

convert -resize '800x480!' input.jpg temp1.png
mkdfiff -f RGB16 temp1.png > temp2.png
dd if=temp2.png of=/dev/fb1

Note that your DisplayLink is probably at /dev/fb1, but you can check with dmesg :

[581145.816821] udlfb: DisplayLink Kensington M01063 - serial #202241900817
[581145.817000] udlfb: vendor descriptor length:22 data:22 5f 01 0020 05 00 01 03 00 04
[581145.817005] udlfb: DL chip limited to 2360000 pixel modes
[581145.909488] udlfb: DisplayLink USB device /dev/fb1 attached. 800x480 resolution.

Only version 1 DisplayLink chips are supported by Linux. The DisplayLink 1 chips are limited to 16 bit RGB. Getting the device to work properly under X windows is more challenging.

thank you the above confirmed my monitor can work. I wish there was a write up on how to install if though – vishal Oct 2 '14 at 15:12
You can use the framebuffer directly from VLC: vlc --vout fb --no-fb-tty --fbdev /dev/fb1 video.mp4 – eosrei Apr 25 at 8:11
