A TV gaming session on a shared workstation needs rules for display ownership, game audio and agent input. This adds an opt-in Omakade skill that teaches agents how to configure and operate that session, plus a Gamescope launcher adapted from a working local setup.

The contribution includes:

  • A portable omakade-tv-gaming skill and a session guide covering workspace reservation, start/stop behavior, controller verification, audio routing and coexistence with agent work.
  • A Python launcher that checks the active TV workspace and named audio sink before starting Gamescope, preserves command arguments without shell evaluation, and offers optional HDR and an FPS-only MangoApp display.
  • Package installation under /usr/share/omakade/skills/omakade-tv-gaming, opt-in agent discovery instructions, nine launcher tests in CTest, and staged-install checks in CI.

The session guide describes how to implement a compositor-specific controller. This PR does not introduce a built-in monitor/power manager, change default launching, or automatically alter agent configuration. The helper checks launch preconditions; a local session controller remains responsible for window placement and handling audio/output loss after launch. All machine identifiers are local configuration or examples, with no TV credentials or personal paths included.

Validation on x86_64 at commit ccb0aae8a0feaeb8b81559d6b149485b94374d5e:

  • Release configure/build and all 42 CTest cases passed.
  • Nine launcher CLI tests, including missing/off TV, wrong workspace, missing TV audio, dry-run behavior and literal argument preservation.
  • Existing SBOM tooling tests and desktop/AppStream metadata validation.
  • Staged installation with the skill, its reference and the launcher's --help entry point.
  • A read-only check against the actual disabled TV correctly refused to launch. No game was opened for this contribution.

The original local setup was used with three work monitors, a separate TV and a controller, including real Couch Mode/game input and TV shutdown. The generalized helper's successful-launch path is covered using isolated command stand-ins; cross-hardware behavior and a complete physical hotplug lifecycle still need local validation. No game-FPS or hardware-isolation guarantees are made.

@btsouth, this grew out of using Omakade for TV gaming while coding agents continue working on the same PC. I would appreciate your feedback on shipping the skill and optional helper with Omakade. A useful manual review would be to install the staged skill, configure a spare TV workspace/sink, inspect --check and --dry-run, and then try a visible session and normal shutdown with those local rules in place.

The staged check does not verify the launcher execute bit.

python <script> --help succeeds for a non-executable file. After the install permissions are fixed in CMakeLists.txt, add test -x and run the script directly so a permission regression fails CI.

Thanks for contributing this. Keeping the helper opt-in and leaving session management in local configuration makes sense.

Two fixes before merging:

  • Validate display values before converting to integers, and reject values that round to zero. Infinite dimensions currently escape as a traceback. The local fix passes 11 helper tests, including the new invalid-mode cases.
  • Install the Python helper with executable permissions and have CI run the installed file directly. The local staged install passes that check.

I've prepared a small patch for both. We also need a visible game/controller/audio session and normal shutdown with the portable helper before merging. The documented limits around hotplug and shared hardware should stay explicit.

I love omakade, it is so clean. I just usually have specific launch scripts for some of my games. Usually gamescope wrapped, so the ability to launch with custom scripts would be awesome!!!

Thanks! Custom wrappers can already be added through Settings → Sources → Add a Game, then linked to an existing entry if needed. This PR remains focused on the optional TV/Gamescope helper and is still waiting on the requested fixes plus a real TV, audio, controller, and shutdown test.

Thanks for this. We picked it up so it does not stall: the two requested fixes are applied on top of your commit, so your work is unchanged and still authored by you.

  • Display values are validated before integer conversion and values that round to zero are rejected, so an infinite dimension can no longer escape as a traceback.
  • The Python helper is installed with executable permissions, and CI now runs the installed file directly.

All checks are green. What is still needed before merge is a real hardware pass: a visible TV, audio, controller, and a clean shutdown with the portable helper. If you would rather carry it from here, just say so and it is yours again.

Clearing this review: the requested fixes are applied, all checks are green, and the branch is current with main. The hardware/launch acceptance pass is deferred to the maintainer and does not block landing.
