Linux kernel version 6 not supported - patch available

VGerris commented 1 year ago

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

problem: Building module: Cleaning build area... make -j16 KERNELRELEASE=6.0.5-200.fc36.x86_64 all INCLUDEDIR=/lib/modules/6.0.5-200.fc36.x86_64/build/include KVERSION=6.0.5-200.fc36.x86_64 DKMS_BUILD=1...(bad exit status: 2) Error! Bad return status for module build on kernel: 6.0.5-200.fc36.x86_64 (x86_64)

This is the same issue as on Ubuntu

VGerris commented 1 year ago

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.

dominikzogg commented 1 year ago

@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 git@github.com: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.

mortezaalizadeh commented 1 year ago

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

simcax commented 1 year ago

That worked for me :-) Thank you @dominikzogg . perfect fix

onel0p3z commented 1 year ago

@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!

Btw 6.2 is going to need another patch:
