Arch Linux User Repository

Rhinoceros, I might be wrong as I'm not an experienced user but it seems like you just didn't install a kernel headers package. AFAIK, it's not a dependency as you can have different kernels on your system, each kernel has its own headers package and this is a dkms module that requires the headers to compile. so you have to install it as well, depending on what kernel you have, for linux it's linux-headers. the kernel you're using could be found using pacman/yay/paru, something like pacman -Qs linux kernel. If you have other DKMS modules installed and working, then it's not that.

I can't seem to install this package. I get these errors when attempting to install

I then tried rebooting, which didn't help, so I tried the other suggestion.

$ sudo modprobe legion-laptop
modprobe: FATAL: Module legion-laptop not found in directory /lib/modules/6.15.9-arch1-1

Indeed, there is nothing installed by this package into /lib/modules/6.15.9-arch1-1. Is that expected?

Try removing your local PKGBUILD cache, e.g. the $HOME/.cache/paru/clone/lenovolegionlinux-dkms-git directory. (Older versions of this PKGBUILD strangely pin to a certain commit despite being a -git package) The upstream has already fixed the compilation problems.

Please update this, it doesn't compile on kernel 6.14.6 at all, exiting with error:

Please update. It doesn't work on kernels version 13 and last 14.

Consult /var/lib/dkms/lenovolegionlinux/1.0.0/build/make.log for more information. ==> WARNING: `dkms install --no-depmod lenovolegionlinux/1.0.0 -k 6.14.0-rc7-1-mainline' exited 10

Should we install both DKMS and the other version (lenovolegionlinux-git) if we want the DKMS functionality ? Or should we only install DKMS?
