- common-nixos: nix.settings.auto-optimise-store + larger download buffer. - workstation: fstrim, boot.tmp.cleanOnBoot, and the shared graphical options moved here from the per-host configs (pipewire, swaylock PAM stub, redistributable firmware) -- MBP-Asahi gains audio it lacked. - T400: zramSwap for the low-RAM host. - MBP-Asahi: nixos-apple-silicon binary cache substituter. - MacPro31 README: describe the real (LVM/UUID) hardware config; it is no longer a placeholder.

# Mac Pro 3,1 (Early 2008) — install notes
|
|
|
|
Flake host: `lyrathorpe-macpro31`. Desktop (`portable = false`, imports
|
|
`../../modules/desktop.nix`). Files: `configuration.nix`,
|
|
`hardware-configuration.nix`.
|
|
|
|
## Hardware configuration
|
|
|
|
`hardware-configuration.nix` here is the real config generated by
|
|
`nixos-generate-config` on the machine. Root is an **LVM** logical volume
|
|
(`/dev/mapper/MacPro-Root`, ext4); the ESP (vfat) and swap are referenced by
|
|
UUID. The initrd carries `dm-snapshot` for the LVM root. Regenerate and commit
|
|
if the disk layout changes.
|
|
|
|
## Bootloader
|
|
|
|
The Mac Pro 3,1 has **64-bit EFI**, so it uses **systemd-boot** (no GRUB/CSM
|
|
shim). `canTouchEfiVariables = false` because Apple's firmware does not reliably
|
|
accept `efibootmgr` NVRAM writes.
|
|
|
|
Apple-EFI quirk: if the firmware boot picker does not show NixOS after install,
|
|
either
|
|
|
|
- uncomment `boot.loader.efi.efiInstallAsRemovable = true;` in
|
|
`configuration.nix` (installs the fallback `\EFI\BOOT\BOOTX64.EFI`), and/or
|
|
- "bless" the ESP from macOS.
|
|
|
|
Partition the disk GPT with an ESP (vfat).
|
|
|
|
## Graphics
|
|
|
|
The stock card varies between units — **ATI Radeon HD 2600 XT** or **NVIDIA
|
|
GeForce 8800 GT**. No proprietary driver is hardcoded; Sway relies on in-tree KMS:
|
|
|
|
- ATI Radeon HD 2600 XT → `radeon` (or `amdgpu`) KMS
|
|
- NVIDIA GeForce 8800 GT → `nouveau` KMS
|
|
|
|
These come up automatically. If a card needs forcing, set
|
|
`services.xserver.videoDrivers` and/or add the module to
|
|
`boot.initrd.kernelModules` for early KMS (see the comment in
|
|
`configuration.nix`).
|
|
|
|
## Networking
|
|
|
|
Wired Ethernet via NetworkManager (from `desktop.nix`) — the Mac Pro has two
|
|
gigabit ports.
|
|
|
|
## Login
|
|
|
|
Graphical login via a Wayland greeter — `greetd` running ReGreet inside the
|
|
`cage` kiosk compositor — configured centrally in `lyrathorpe/swaywm.nix` for
|
|
every Sway host (gated on `features.swayDesktop.enable`). The greeter is forced
|
|
to the Dvorak layout to match the console and Sway session. Set the user
|
|
password (`passwd lyrathorpe`) after install, or the greeter cannot
|
|
authenticate. Requires working KMS (radeon/nouveau — see Graphics).
|
|
|
|
## Apply
|
|
|
|
```sh
|
|
sudo nixos-rebuild switch --flake .#lyrathorpe-macpro31
|
|
```
