I am using awesomewm and used to have
services.xserver.videoDrivers = [ "nvidia" ];
boot.kernelPackages = pkgs.linuxPackages_latest;
in my configuration.nix and it worked up until and including linux 5.19. When linux 5.19 reached EOL, the package for nvidia wasn’t compatible with linux 6.0 on Nixos 22.05 so i had to use the following:
let
unstable = import <nixos-unstable> {
### override für Nvidia unstable
config.allowUnfreePredicate = pkg:
builtins.elem (lib.getName pkg) [ "nvidia-x11" "nvidia-settings" ];
};
in {
services.xserver.videoDrivers = [ "nvidia" ];
boot.kernelPackages = unstable.pkgs.linuxPackages_latest;
This worked and since i upgraded to Nixos 22.11 i can build Nixos with my original configuration again. However, after rebooting the xserver fails to start and i’m stuck in SDDM. I can enter the terminal there and see, that the xserver is the problem.
If i apply my overrides again and reboot, the xserver works but i would like to solve this problem to be able to drop the overrides. I was thinking that this problem would be solved shortly after the release of Nixos 22.11 but so far it hasn’t happened.
Can i solve this problem myself?
