These are the steps to make the Wavlink WL-UG6902H USB to HDMI adapter work on Ubuntu and Fedora Linux. It's a rather simple and straight forward process. The tricky part was figuring out that it needs the SMI USB driver (Silicon Motion) and the Displaylink driver (Synaptics).
If you're here for the Fedora installation, head to my repo weblink-fedora.
https://www.wavlink.com/en_us/product/WL-UG6902H.html
Download the latest driver on the Silicon Motion driver page (search for Linux).
You'll download a file named SMI-USB-Display-for-Linux-v2.22.1.0.zip
Unzip the file you previously downloaded:
unzip SMI-USB-Display-for-Linux-v2.22.1.0.zipThis extracts a file named SMIUSBDisplay-driver.2.22.1.0.run.
Then run the following commands:
chmod +x SMIUSBDisplay-driver.2.22.1.0.run
sudo ./SMIUSBDisplay-driver.2.22.1.0.runThe device should start working straight away.
I was able to port the installation process to Fedora 41 and now I'm able to use the device on Fedora as well.
Maybe it works on another Red Hat based distros (and versions), but it's your job to test it! 😉
You can get the code I used on my weblink-fedora repo. Instructions can be found on its README.md file.
- Cleanup the Fedora installation process.
- Make it possible to uninstall the SMI and EVDI drivers.
