How to install DisplayLink software on Ubuntu

The latest software for Ubuntu 14.04.2 LTS can be downloaded from the DisplayLink website. This will download a .zip file.

The minimum supported kernel version is 3.16 and xorg version 1.16. These were provided in the 14.04.2 point release. See this link for more information:

https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes#LTS_Hardware_Enablement_Stack

It might be neccessary to manually opt into this new stack on previous 14.04.0 and 14.04.1 releases by running following command which will install the linux-generic-lts-utopic and xserver-xorg-lts-utopic packages: 

sudo apt-get install linux-generic-lts-utopic xserver-xorg-lts-utopic libegl1-mesa-drivers-lts-utopic xserver-xorg-video-all-lts-utopic xserver-xorg-input-all-lts-utopic 

If you are on an amd64 system that boots with UEFI, you will also need the matching signed kernel: 

sudo apt-get install linux-signed-generic-lts-utopic 
  1. IMPORTANT: Make sure your Ubuntu distibution is up to date by running sudo apt-get update and then sudo apt-get dist-upgrade from a Terminal. If the distribution is not up to date, you may find issues with blank or corrupted USB displays.
  2. Extract the .run file from the .zip file.
  3. Make the .run file executable by right clicking on the file and choose "Properties".

    Check the "Allow executing file as a program" box.
  4. Install the DKMS framework from a Terminal using the command sudo apt-get install dkms
  5. Execute the DisplayLink .run file using the Terminal, by cding to the directory containing the .run file and running the command sudo ./displaylink-driver-xxxxx.run (where xxxx is the version number)
  6. The DisplayLink software should install as shown below.
  7. You can now connect your DisplayLink products to the computer
Note: The DisplayLink .run file just provides support for the video outputs. Audio and Ethernet support are provided by the native Ubuntu drivers.

Please note that we have not tested compatibility with newer kernel versions, and changes in DRM they include. It is possible that the evdi kernel module would need modifications to work properly. Contributions to evdi are welcome.
