The docs-site build syncs this repo's README.md and docs/ into the site tree; nothing else is copied. All prose apart from the README therefore lived outside the sync and never appeared on https://docs.lyrapup.pet/nixfiles/, and the one page that did publish carried 18 link targets that resolved to nothing. Moves: home/README.md -> docs/shell.md home/KEYBINDINGS.md -> docs/keybindings.md hosts/<Name>/README.md -> docs/hosts/<name>.md docs/.pages and docs/hosts/.pages give the awesome-pages plugin an explicit order; new pages are picked up by the trailing '...' without an edit. Links are rewritten so a single URL is correct in both Gitea and the published site: absolute Gitea source URLs for .nix files and directories, relative links between pages under docs/, and absolute docs.lyrapup.pet URLs from the root README, which the build republishes at a different depth from the rest of the tree. In-code comments that pointed at a moved README are updated to the new path. The README gains a Documentation section covering the sync contract and the linking rules, and CLAUDE.md carries the short version so future edits do not reintroduce unsynced pages or dead links. Verified by reproducing the docs-site assembly locally against its pinned toolchain (mkdocs 1.6.1, mkdocs-material 9.7.7, awesome-pages 2.10.1): pages render at the URLs used above and in the declared order.

# ThinkPad T400 — install notes
|
|
|
|
Flake host: `lyrathorpe-t400`. Files: `configuration.nix`, the `boot-*.nix`
|
|
variants, and `hardware-configuration.nix`.
|
|
|
|
## Hardware configuration
|
|
|
|
`hardware-configuration.nix` here is a hand-written **placeholder**. On the real
|
|
machine, run `nixos-generate-config`, replace the file, and commit it. It assumes
|
|
by-label partitions — root `nixos` (ext4) and `swap` — so either label them at
|
|
install time or swap in the generated UUIDs.
|
|
|
|
## Bootloader — import the module matching the flashed firmware
|
|
|
|
`configuration.nix` imports exactly one boot module. Default is `boot-bios.nix`;
|
|
switch by commenting it out and uncommenting the relevant alternative.
|
|
|
|
| Firmware | Module | Notes |
|
|
| ---------------------------------------------------- | ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
|
| Stock Lenovo BIOS, or coreboot + **SeaBIOS** payload | `boot-bios.nix` | GRUB on the MBR. Set `device` to the real install disk (`/dev/sda` by default). MBR/legacy layout. |
|
|
| coreboot + **GRUB** payload | `boot-coreboot-grub.nix` | GRUB is config-only (`device = "nodev"`); NixOS does **not** write to a disk. Your coreboot `grub.cfg` (in the flash chip) must `search` for and `configfile` the on-disk `/boot/grub/grub.cfg`, or chainload the disk's GRUB. |
|
|
| coreboot + **Tianocore/edk2 (UEFI)** payload | `boot-coreboot-uefi.nix` | systemd-boot. `canTouchEfiVariables = true` (coreboot honours NVRAM writes). The module **declares its own ESP** (`/boot` vfat, label `ESP`) — when you regenerate `hardware-configuration.nix`, do **not** let it also define `/boot`. Create + label an `ESP` vfat partition (GPT). |
|
|
|
|
## Graphics
|
|
|
|
This unit has the optional **discrete ATI Mobility Radeon HD 3470 (RV620)**. The
|
|
open `radeon` KMS driver is loaded in the initrd for early modesetting; firmware
|
|
comes from `enableRedistributableFirmware`.
|
|
|
|
The T400 has switchable graphics (discrete ATI + Intel GMA 4500MHD). Select
|
|
**Discrete** in the firmware's graphics setting so only the ATI is live. If you
|
|
run **Integrated** instead, the Intel `i915` driver takes over with no config
|
|
change and `radeon` stays idle.
|
|
|
|
## Login
|
|
|
|
Graphical login via a Wayland greeter — `greetd` running ReGreet inside the
|
|
`cage` kiosk compositor — configured centrally in `../../modules/sway.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 radeon/i915 KMS (see Graphics).
|
|
|
|
## Apply
|
|
|
|
```sh
|
|
sudo nixos-rebuild switch --flake .#lyrathorpe-t400
|
|
```
