i want my base config(the one that is booted automatically into) to NOT use the dgpu at all, and i want a specialisation that has nvidia enabled for full power consumption(i have a laptop).
i have attatched both files below.
The problem i am facing is that, the default config is still using nouveau even though it is blacklisted. gaming-time is working well.
# default.nix
boot = {
extraModprobeConfig = lib.mkDefault ''
blacklist nouveau
options nouveau modeset=0
'';
blacklistedKernelModules = lib.mkDefault [
"nouveau"
"nvidia"
"nvidiafb"
"nvidia_drm"
"nvidia-uvm"
"nvidia_modeset"
"nv"
"rivafb"
"rivatv"
"ipmi_msghandler"
"ipmi_devintf"
];
};
services.udev.extraRules = lib.mkDefault ''
