Issue/Bug Description:

I believe I have tracked down the cause of this issue: https://github.com/pop-os/nvidia-graphics-drivers/issues/170 to this block of code in crates/hardware/src/switchable_graphics.rs:

match default_graphics().as_str() {
        "integrated" => {
            info!("disabling external NVIDIA graphics by default");
            fs::write(mount_dir.join(POWER), MODPROBE_INTEGRATED)?;

            info!("configuring gpu-manager for integrated graphics mode");
            fs::write(mount_dir.join(PRIME_DISCRETE), "off")?;
        },
        "hybrid" => {
            info!("settings module options for hybrid graphics mode");
            fs::write(mount_dir.join(POWER), MODPROBE_HYBRID)?;

            info!("configuring gpu-manager for hybrid graphics mode");
            fs::write(mount_dir.join(PRIME_DISCRETE), "on-demand")?;
        },
        _ => (),
    }

If a GTX 1030 or RTX 4090 are installed in the system during setup it proceeds as though the system is only using integrated graphics

Steps to reproduce (if you know):

1) Install a GTX 1030 or RTX 4090 into the system with display out plugged into discrete GPU (make sure integrated graphics is enabled in BIOS) 2) install Pop! OS 22.04 from live media 3) on reboot after installing system hangs until display out plugged in to integrated graphics

Expected behavior:

System is supposed to boot normally
