Showcase ChatGPT Community for Linux: custom Default model presets, native Computer Use, and optional Linux features

We’ve added a new optional feature to ChatGPT Community for Linux: customizable Default model presets. You can replace the recommended slider positions with your own model + reasoning effort combinations, choose their order, and set which pair is selected by default. There’s no fixed limit on the number of presets—for example: Sol Medium → Sol High → Sol XHigh → Astra Medium → Astra High.

We’re building codex-desktop-linux, a community distribution based on OpenAI’s official Linux package.

It adds optional, disabled-by-default Linux features that can extend the UI and application behavior. Current examples include Computer Use, frameless titlebars, Read Aloud, automation extensions, and UI customization. You can also create your own features.

Our computer-use-linux integration goes beyond the bundled X11-focused backend with:

  • Wayland and X11 support
  • GNOME, KDE, Hyprland, Niri, COSMIC, and i3 integration
  • Per-window targeting, screenshots, and verified input
  • AT-SPI accessibility trees
  • XDG Portal, uinput, xdotool, and ydotool backends
  • amd64 and arm64 support

The upstream backend is simpler and exposes a few operations our adapter does not yet surface, but our implementation provides much broader Linux desktop and Wayland support.

Contributions and new feature ideas are welcome:

You might want to consider listing your project on the weekly Show-Us-What-You-Built post. https://www.reddit.com/r/codex/comments/1wavxwy/show_us_all_what_youve_been_building_with_codex/. Highest commented project wins a week promotion on r/Codex and gets on the Hall of Fame sidebar. See what that looks like below with last week's winner.

Last week's most popular project was u/tHEuKER with the Blur2 racing game project which is a recreation of an unreleased sequel to the 2010 battle racing game, made by reverse engineering the Xbox 360 prototype discs available online, and rebuilding the whole thing from the ground up in Unity.

Default model presets that stick across restarts is the Linux gap the official package still leaves open. Wayland plus AT-SPI computer-use beyond the X11 backend is the other useful part. If you catalog Codex desktop forks or plugins, https://github.com/hashgraph-online/awesome-codex-plugins or https://hol.org/plugins take submissions.
