Fails to install `<nixos-hardware/asus/zephyrus/ga402x/nvidia>` on GA402XY when running on `boot.kernelPackages = pkgs.linuxPackages_lqx`

[caniko]

The header speaks for itself.

I get this error when running either nixos-rebuilt boot or switch:

subprocess.CalledProcessError: Command '['/nix/store/gafgm1kn3sgl2nq79ihsb6jdv39s81pr-nix-2.18.5/bin/nix-env', '--list-generations', '-p', '/nix/var/nix/profiles/system', '--option', 'build-users-group', '']' died with <Signals.SIGSEGV: 11>.

I have to revert to the previous build to build new builds after this error. Very annoying 😆

When I don't have linux_lqd installed the installation succeeds, but the build fails to boot, and I am taken to tty1. When trying to kde-start I am told that no candidate was found, the list of candidates comes up (you know how it is)... Will create a separate issue for this later.

GA402XY has an RTX 4090 in addition to the iGPU, hope we can get this working.

I don't think this is a bug in nixos-hardware but in nix-env itself. It looks like this error comes from the systemd-boot builder:

subprocess.CalledProcessError: Command '['/nix/store/gafgm1kn3sgl2nq79ihsb6jdv39s81pr-nix-2.18.5/bin/nix-env', '--list-generations', '-p', '/nix/var/nix/profiles/system', '--option', 'build-users-group', '']' died with <Signals.SIGSEGV: 11>.

Can you run it in isolation and see if you have more error output from nix-env? Do a nixos-rebuild test instead to only update /nix/varnix/profiles/system without installing any bootloader.

This was in isolation, and it wasn't working. NixOS just doesn't play nice with anything other than the LTS kernel... I would say that this part of the issue is out of scope for your efforts. Very thankful for that, by the way!

I fixed this, the issue was my KDE configuration: It was still in X11, fixed after switching to Wayland.
