@Strykar Yes, lkrg will have to issue a new release to fix that. In the meantime lkrg-dkms-git seems to work for me.

Aur package builds fine but DKMS fails with:

==> dkms install --no-depmod lkrg/0.9.8 -k 6.11.1-arch1-1
Error! Bad return status for module build on kernel: 6.11.1-arch1-1 (x86_64)

@ruonim: Would you mind looking at dmesg right after getting this error? It should tell us more about what is going on. It would be very useful if you could tell us the exact version of the kernel you are running.

@dubster: You are completely right, it should be fixed now! Many thanks!

Awesome, thanks for getting this updated @rgacogne!

The one thing I'll note is that the systemd service (when installed by a package) might need to be installed in /usr/lib/systemd/system. I believe that /etc/systemd/system is for admin user management, but packages install files into /usr/lib/systemd/system.

You can see an example of this in the mullvad-vpn package: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=mullvad-vpn-cli#n116

Seems to be related to the zen kernel.

It works as expected for me on 6.6.4-arch1-1:

Service errors out:

@dubster: I just added the systemd service and the default configuration file to the package. I'm not going to enable the LKRG service automatically, though, as per Arch policy. Thanks for the hint!
