I recently purchased an AOC E2251FWU DisplayLink monitor. When I plug this into my System76 Gazelle Professional running Ubuntu 13.04 Raring Ringtail, nothing happens. Under 'displays', no additional display is detected. On Mac and Windows, this monitor is plug-and-play after installing DisplayLink's drivers.

Having read that previous versions of Ubuntu had plug and play support for DisplayLink monitors, I'm surprised that Ubuntu 13.04 does not! The 'xserver-xorg-displaylink' driver is not available in the 13.04 repositories. I read that it has become baked into the Linux kernel.

Does anybody know how to get a DisplayLink device to actually work on Ubuntu 13.04? I'm looking to get a simple extended display. I've done my due dilligence and Googled around, but no solution I can find works for me.

  • So this only work for USB monitor only? (I have nvr seen a usb monitor). I bought a normal monitor and it just come up with a green screen. – Timothy Leung Jul 3 '14 at 6:37

Woohoo, I found a solution (no extra adapter required)!

In Ubuntu 13.04, installing the precompiled 3.9 raring kernel from kernel.ubuntu.com makes my display plug-and-play. Using the "Displays" utility, mirroring and extended desktop both work. It's not 100% buttery smooth, but it works. The Saucy 3.10.1 kernel also works just fine with Raring. I can't tell any difference between the 3.9 and 3.10 kernels in terms of DisplayLink.

If your DisplayLink monitor does not work out of the box with Ubuntu 12.10 or 13.04, installing Linux kernel 3.9 or higher may "just work". Apparently the baked in DisplayLink drivers have been improved.

Installing a prebuilt kernel is simple; download the header and image deb files for the kernel of your choice (3 files total). Install the headers first, then the kernel image. Next time you reboot, you should be using the updated kernel (check the version with "uname -r"). If you want to boot into an older kernel again, holding the shift key while your computer is booting will bring up a menu that allows you to select which kernel to boot. If you have issues with a new kernel, you can always uninstall it. I recommend using Synaptic to do so.

  • Yes, I found under Arch Linux too that things just work, finally. I needed to blacklist the udlfb kernel module and install the xorg modesetting driver -- but after that it just works. – chx Jul 26 '13 at 18:08
  • When I plug in, the monitor powers and displays alternating maroon & marine bars. Do you know how to fix that? My situation here: unix.stackexchange.com/questions/89585/… – user128334 Sep 5 '13 at 23:48
  • That looks like a "fun" problem. Sorry, no I don't. – Tom D Sep 7 '13 at 20:02
  • funniest issue: I got the same issue as user128334, but if I jump to TTY1 (Ctrl+Alt+F1) my terminal actually loads in the USB screen! hahaha with those bars, but I'm unable to turn it on with X... – igorsantos07 Oct 11 '14 at 15:23

As an intermediate step, you can place a static image on a DisplayLink device using the instructions here: https://askubuntu.com/a/393117/46709 If the static image works, then stepping up to the 3.9 Kernel has a chance of working.
