*Mostly copied from 15-9550

|
== Tested Hardware ==
|
|
|
|
* CPU: Intel(R) Core(TM) i9-9980HK
|
|
* RAM: 32 GB
|
|
* HDD: 1 TiB SSD
|
|
* Screen: 15" 4k (3840✕2160)
|
|
* Input: Touchscreen and trackpad.
|
|
|
|
== Firmware Configuration ==
|
|
|
|
Not much tweaking of NixOS itself was needed. But we currently cannot automate the firmware setup, so this must be done by hand.
|
|
|
|
=== Before installation ===
|
|
|
|
These settings are needed both for booting the final install, and installer itself. Therefore, they must be done first.
|
|
|
|
* ''Disable Secure Boot (but keep UEFI Boot).'' Thankfully doing so is as easy as changing any other simple setting.
|
|
|
|
* ''Disable Intel hardware RAID and use AHCI instead.'' Intel doesn't seem to provide a working linux driver for this. (If you just have SSD it's pointless and just slows things down needlessly anyways.)
|
|
|
|
=== Wifi ===
|
|
~~Wifi does not work with kernels older than 5.1 (firmware not present) or newer~~ (https://bbs.archlinux.org/viewtopic.php?id=247705)
|
|
|
|
Update: The 48.ucode causes the Killer wifi card to crash. The iwlfwifi-cc-a0-46.ucode works perfectly.
|
|
default.nix contains an overlay that removes the offending ucode from the linux-firmware bundle.
|
|
To use it one also needs to enable unfree firmware in their own configuration (<code>hardware.enableRedistributableFirmware = true;</code>)
|
|
|
|
```
|
|
# Use the systemd-boot EFI boot loader.
|
|
boot.loader.systemd-boot.enable = true;
|
|
boot.loader.grub = {
|
|
device = "nodev";
|
|
efiSupport = true;
|
|
efiInstallAsRemovable = true;
|
|
};
|
|
boot.loader.efi.canTouchEfiVariables = true;
|
|
boot.kernelPackages = pkgs.linuxPackages_5_1;
|
|
```
|
|
Disable the `canTouchEfiVariables` after a boot or two to prevent NVRAM wearout.
|
|
|
|
|
|
=== After installation ===
|
|
|
|
* ''Add systemd-boot to UEFI boot list.'' The (uneditable anyways) settings mapping drive UUIDs to HD* work fine.
|
|
|
|
=== Optional ===
|
|
|
|
* ''Update BIOS.'' According to Reddit, this helps with battery life.
|
|
|
|
=== Troubleshooting ===
