Linux kernel version 6 not supported - patch available
- Are you using the latest driver? yes * Are you using the latest EVDI version?
- If you are using a DisplayLink device, have you checked 'troubleshooting' on DisplayLink's website? yes
- Is this issue related to evdi/kernel? yes, kernel v6
- Linux distribution and its version - Fedora 36 Workstation
- Linux kernel version : Linux fedora 6.0.5-200.fc36.x86_64 #1 SMP PREEMPT_DYNAMIC Wed Oct 26 15:55:21 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
- Xorg version (if used) - no Wayland
- Desktop environment in use Gnome
Installing the driver fails on kernel version 6 and up. This has been reported here, including a patch : https://github.com/DisplayLink/evdi/issues/376

Apologies, I missed : https://github.com/DisplayLink/evdi/pull/381 So it seems the fix is applied. Will this be released soon and can the issue be used to track that? Otherwise feel free to close it, thank you.
@VGerris in the meanwhile you can compile it yourself, as far as i can tell it should be automatically recompiled on kernel upgrade
Thats how i did it (written based on what i remember)
git clone [email protected]:DisplayLink/evdi.git
sudo mv evdi /usr/src/evdi
cd /usr/src
sudo mv evdi-1.12.0 evdi-1.12.0-backup
sudo ln -s evdi/module evdi-1.12.0
cd evdi-1.12.0
sudo make
sudo make install
This way you can also which branch / pull, adapt if changes are needed. If you reinstall or upgrade the package (rpm) the changes will be overridden.
hey guys, any chance when the merged patch can be released? I am left with one monitor only and it is an absolute pain. Cheers
@dominikzogg thanks for the help! I had to follow the steps from https://github.com/andikleen/simple-pt/issues/8#issuecomment-813438385 because I was getting the certs not found error, then ran sudo dkms add . after sudo make install so that I could get the driver to install properly because it kept failing with an error along the lines dkms module not found. After rebooting, I was able to use my USB type-c monitor 🎉 Thanks!
kernel: 6.0.6 os: pop_os 22.04
Btw 6.2 is going to need another patch:
