feat(sleep-inhibitor): add Linux and Windows idle-sleep prevention (#11766)
## Background
- follow-up to previous macOS-only PR:
https://github.com/openai/codex/pull/11711
- follow-up macOS refactor PR (current structural approach used here):
https://github.com/openai/codex/pull/12340

## Summary
- extend `codex-utils-sleep-inhibitor` with Linux and Windows backends
while preserving existing macOS behavior
- Linux backend:
  - use `systemd-inhibit` (`--what=idle --mode=block`) when available
- fall back to `gnome-session-inhibit` (`--inhibit idle`) when available
  - keep no-op behavior if neither backend exists on host
- Windows backend:
- use Win32 power request handles (`PowerCreateRequest` +
`PowerSetRequest` / `PowerClearRequest`) with
`PowerRequestSystemRequired`
- make `prevent_idle_sleep` Experimental on macOS/Linux/Windows; keep
under development on other targets

## Testing
- `just fmt`
- `cargo test -p codex-utils-sleep-inhibitor`
- `cargo test -p codex-core features::tests::`
- `cargo test -p codex-tui chatwidget::tests::`
- `just fix -p codex-utils-sleep-inhibitor`
- `just fix -p codex-core`

## Semantics and API references
- Goal remains: prevent idle system sleep while a turn is running.
- Linux:
  - `systemd-inhibit` / login1 inhibitor model:
-
https://www.freedesktop.org/software/systemd/man/latest/systemd-inhibit.html
-
https://www.freedesktop.org/software/systemd/man/org.freedesktop.login1.html
    - https://systemd.io/INHIBITOR_LOCKS/
  - xdg-desktop-portal Inhibit (relevant for sandboxed apps):
-
https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.Inhibit.html
- Windows:
  - `PowerCreateRequest`:

  - `PowerSetRequest`:
-
https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-powersetrequest
  - `PowerClearRequest`:
-
https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-powerclearrequest
  - `SetThreadExecutionState` (alternative baseline API):

## Chromium vs this PR
- Chromium Linux backend:
-
https://github.com/chromium/chromium/blob/main/services/device/wake_lock/power_save_blocker/power_save_blocker_linux.cc
- Chromium Windows backend:
-
https://github.com/chromium/chromium/blob/main/services/device/wake_lock/power_save_blocker/power_save_blocker_win.cc
- Electron powerSaveBlocker entry point:
-
https://github.com/electron/electron/blob/main/shell/browser/api/electron_api_power_save_blocker.cc

## Why we differ from Chromium
- Linux implementation mechanism:
- Chromium uses in-process D-Bus APIs plus UI-integrated screen-saver
suspension.
- This PR uses command-based inhibitor backends (`systemd-inhibit`,
`gnome-session-inhibit`) instead of linking a Linux D-Bus client in this
crate.
- Reason: keep `codex-utils-sleep-inhibitor` dependency-light and avoid
Linux CI/toolchain fragility from new native D-Bus linkage, while
preserving the same runtime intent (hold an inhibitor while a turn
runs).
- Linux UI integration scope:
- Chromium also uses `display::Screen::SuspendScreenSaver()` in its UI
stack.
- Codex `codex-rs` does not have that display abstraction in this crate,
so this PR scopes Linux behavior to process-level sleep inhibition only.
- Windows wake-lock type breadth:
- Chromium supports both display/system wake-lock types and extra
display-specific handling for some pre-Win11 scenarios.
- Codex’s feature is scoped to turn execution continuity (not forcing
display on), so this PR uses `PowerRequestSystemRequired` only.

npm i -g @openai/codex
or brew install --cask codex

Codex CLI is a coding agent from OpenAI that runs locally on your computer.

Codex CLI splash


If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.


Quickstart

Installing and running Codex CLI

Install globally with your preferred package manager:

# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex

Then simply run codex to get started.

You can also go to the latest GitHub Release and download the appropriate binary for your platform.

Each GitHub Release contains many executables, but in practice, you likely want one of these:

  • macOS
    • Apple Silicon/arm64: codex-aarch64-apple-darwin.tar.gz
    • x86_64 (older Mac hardware): codex-x86_64-apple-darwin.tar.gz
  • Linux
    • x86_64: codex-x86_64-unknown-linux-musl.tar.gz
    • arm64: codex-aarch64-unknown-linux-musl.tar.gz

Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.

Using Codex with your ChatGPT plan
