    I’ve updated this to be for ARM Linux support. EVDI is designed as an open source component to be adapted for different graphics architectures.

    The logs from the DisplayLink binary component are encrypted to protect IP. This is the same on all OSes for DisplayLink binary components.

        So can Display link support ARM+Debian or not ?
        I want to use it on my Asus Tinker Board which SoC architecture is arm v7
        I have compiled the EVDI driver in the kbuild environment and can see the usb device from lsusb cmd, but failed at the cmd of systemctl start dlm.

        linaro@tinkerboard:~$ systemctl status dlm
        * dlm.service - DisplayLink Manager Service
        Loaded: loaded (/lib/systemd/system/dlm.service; static; vendor preset: enabled)

        I have bought a monitor with your product. As a paying customer, I have so many little options to do with this expensive monitor. Why won't you try to be helpful to paying customers? (or customers of customers, whatever it is). Is it that much precious IP that you'd eventually render the end products useless to protect it.

        IP ? I mean what kind of precious secret can be running on DisplayLink or anything. This is not rocket science. did you just invent the world's craziest USB monitor algorithm and extremely powerful players are behind its technology or something?

        I want to run the DisplayLink drivers on a raspberry pi3. In you comment you say you have updated the driver for ARM Linux support. Where do I get this version?

      • Andy Billington commented  ·   ·  Flag as inappropriate

        Is the Ubuntu driver actually an Ubuntu driver, or is it an x86/x64-only Ubuntu driver? On the supported OS list it says Linux - Ubuntu, it doesn't say "Partial", or "Limited" or "x86 only"?
        Thanks!

        I've got an Asus MB168B+ that I'd love to use with a Raspberry Pi 3 running Ubuntu MATE. Support seems sooo close, but no ARM divers. Please oh please just recompile the otherwise working Ubuntu drivers and distribute! It can't be that hard...

        root@bjoern-desktop:/opt/displaylink# uname -a
        Linux bjoern-desktop 4.1.19-v7+ #858 SMP Tue Mar 15 15:56:00 GMT 2016 armv7l armv7l armv7l GNU/Linux
        root@bjoern-desktop:/opt/displaylink# ./DisplayLinkManager
        -bash: ./DisplayLinkManager: cannot execute binary file: Exec format error
        root@bjoern-desktop:/opt/displaylink#

        What to do now?

        For DL 41xx DisplayLink series i have compiled the evdi and the udl module under kernel 4.4.0 for RaspberryPi2 ( and works well, the display is listed under lsusb) the only problem is, the displayLinkManager is not for ARM

        Hi!

        Just confirm this DON'T WORK :

        -- Raspberry Pi 2

        jordi@ubuntu:~/Software/displaylink-driver-1.0.335$ uname -a
        Linux ubuntu 3.18.0-25-rpi2 #26-Ubuntu SMP PREEMPT Sun Jul 5 06:46:34 UTC 2015 armv7l armv7l armv7l GNU/Linux

        jordi@ubuntu:~/Software/displaylink-driver-1.0.335$ sudo ./displaylink-installer.sh
        DisplayLink Linux Software 1.0.335 install script called:
        Distribution discovered: Ubuntu 14.04.4 LTS
        Unsatisfied dependencies. Missing component: Linux headers for running kernel, 3.18.0-25-rpi2.
        This is a fatal error, cannot install DisplayLink Linux Software.

        But I know that a Raspberry Pi 2 with Fedora Linux have not problems to manage the same USB-Monitor...without any extra driver installation...
