= Dell XPS 15 7590 =
|
||||
*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.
|
||||
|
||||
```
|
||||
# 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 ===
