Linux 5.9 and Display Link

[andy_g]

Just wanted to say thanks for the detailed steps to get things working on 5.9.X as I finally did these today

With kernel 5.10 nearly here will this workaround continue to also work for 5.10

Thanks for confirming that this also works on 5.10.X

With a lot of help from SicklCodes I've finally got my Displaylink working under 5.9.10...

I had previously followed the patch from post 2, but this did not appear to work... Among trying lots of different fixes, it seems that a patch from SickCodes' repo seemed to bring it all together...

git clone https://github.com/sickcodes/evdi.git
cd evdi
git checkout -f master
make
sudo make install

It would be great if this could be included with the current DisplayLink offering

It also seems as though the displaylink-driver.service was not starting automatically., but was found to be present from typing 'systemctl status display' and tapping tab twice (without hitting enter).

You can then test whether it will start with 'sudo systemctl start displaylink-driver.service'

This worked for me to bring my additional 2 displays (1xHDMI and 1xDVI) from my DisplayLink adapter... I also had the HDMI straight from my Ryzen 7 laptop (with Nvidia MX350) working in parallel with the DVI from the DisplayLink alongside the laptop screen...

As per January, 1st 2021, all changes have been pushed to branch v.1.7.x: #225.

The updated (simpler) instructions are the following:

1. Download the DisplayLink driver from [the official download page](https://www.displaylink.com/downloads/ubuntu). Then run the following commands:

    unzip 'DisplayLink USB Graphics Software for Ubuntu 5.3.1.zip'
    chmod +x displaylink-driver-5.3.1.34.run
    ./displaylink-driver-5.3.1.34.run --noexec --keep

2. Get the updated evdi version by typing:

    git clone https://github.com/DisplayLink/evdi.git
    cd evdi
    git checkout v1.7.x
    tar cf evdi.tar.gz *
    cp evdi.tar.gz ../displaylink-driver-5.3.1.34

3. Install displaylink:

    cd ../displaylink-driver-5.3.1.34
    sudo ./displaylink-installer.sh install

Tested on Ubuntu 20.04, kernel version 5.10.2 (-surface).
Hope that helps.

I've put together a build script that I use already for my Ubuntu setup... Working for 5.9.16, and just installing 5.10.4 to test that too... But the results from above already speak for themselves... (Thank you bro )

Hopefully this can simplify the process...

It downloads the current DisplayLink, then updates the EVDI folder from the above instructions...

https://github.com/robotard/setup-ub...kdownloader.sh

[AS PER BELOW - I've updated my script to allow for newer DisplayLink updated to not be automatically be patched]

##IMPORTANT##
You may also need to run this to start the service after reboot:

sudo systemctl start displaylink-driver.service

Let me know if it helps

I could probably expand upon it to check whether the current Displaylink is above 5.3.1.34 and install that without the need for any patches, but that's on DisplayLink to fix their sh$t first...

Hopefully updated the script for newer DisplayLink releases...

Please let me know if it works for you and always...

Is there a chance your ubuntu-setup repo is private? If you want to keep it that way, a gist could get the job done!

Ooh, not intentionally, but just a note that the EVDI one is broken again on 5.10.5...

Works fine on 5.10.4 though...

[EDIT]
The original EVDI one, not from my missing script (adding in a second)
