Single-script builder (nosignal.sh) that turns a stock Arch Linux ISO into a fully-offline installer for a themed Hyprland + caelestia (Quickshell) desktop: matching SDDM greeter, Btrfs/Limine bootable snapshots, chwd-style GPU detection, and a curated "os updates" layer (keybind cheatsheet, settings panels, system polish, on-box management skill). See README.md. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# gaming-enablement — multilib repo + omarchy-pkg-add shim
|
|
|
|
Makes Omarchy-targeted Steam/gaming install scripts (e.g. **DeckShift**) work on
|
|
NoSignal. Two gaps were blocking them:
|
|
|
|
1. **`[multilib]` was disabled** in `/etc/pacman.conf` — the 32-bit repo every
|
|
`lib32-*` package (Steam, Wine, gaming libs) lives in. Without it, pacman/yay
|
|
can't see those packages at all.
|
|
2. **`omarchy-pkg-add` doesn't exist** on NoSignal — it ships `yay`/Shelly, not the
|
|
Omarchy CLI helpers, so scripts die at `omarchy-pkg-add: command not found`.
|
|
|
|
## What it does
|
|
|
|
- Uncomments the `[multilib]` block in `/etc/pacman.conf` (leaving
|
|
`[multilib-testing]` alone) and runs `pacman -Sy`.
|
|
- Installs **Omarchy CLI shims** → `~/.local/bin` (NoSignal ships yay + the
|
|
caelestia launcher, not the Omarchy helpers DeckShift expects):
|
|
|
|
| Shim | NoSignal behaviour |
|
|
|------|------------------|
|
|
| `omarchy-pkg-add` | `yay -S --needed --noconfirm "$@"` (idempotent installs) |
|
|
| `omarchy-install-gaming-steam` | `yay -S steam` + best-effort first launch (needs multilib) |
|
|
| `omarchy-hw-nvidia-gsp` | exit 0 if an NVIDIA GPU is present (modern/GSP branch) |
|
|
| `omarchy-hw-nvidia-without-gsp` | exit 1 (defaults to modern branch; see note) |
|
|
| `omarchy-restart-walker` | no Walker here — refresh desktop DB, succeed |
|
|
|
|
The NVIDIA shims default any present card to the modern (`nvidia-utils`)
|
|
branch; pre-Turing cards need `nvidia-580xx-*` by hand. On this AMD+Intel box
|
|
both correctly report "no NVIDIA".
|
|
|
|
## Install
|
|
|
|
```sh
|
|
sh install-gaming-enablement.sh # needs sudo for the pacman.conf edit + sync
|
|
```
|
|
|
|
After this, `./deckshift.sh` (and similar) find their deps and proceed. Note:
|
|
DeckShift also *optionally* calls `omarchy-install-gaming-steam`,
|
|
`omarchy-hw-nvidia-gsp`, `omarchy-restart-walker` — those are `command -v`-guarded
|
|
in the script, so they're skipped harmlessly (only `omarchy-pkg-add` was fatal).
|
|
|
|
## Builder notes
|
|
|
|
For a gaming-capable ISO:
|
|
- **Enable `[multilib]` in the image's `/etc/pacman.conf` by default** (uncomment
|
|
the two lines) and sync in the build.
|
|
- **Ship `omarchy-pkg-add`** in `~/.local/bin` (or `/usr/local/bin`). Consider
|
|
shipping the other commonly-referenced Omarchy helpers
|
|
(`omarchy-install-gaming-steam`, `omarchy-hw-nvidia-*`, `omarchy-restart-walker`)
|
|
as shims if broad Omarchy-script compatibility is wanted.
|
|
- This pairs naturally with shipping `gamemode` / `lib32-*` Steam deps in the
|
|
base if gaming is a first-class use case.
|
|
|
|
This is a **package/repo-config delta** (unlike the other changes) — it touches
|
|
the package list / pacman.conf rather than dropping a self-contained component.
