# Setting Up Codex + ChatGPT Desktop on Linux for Terminal-Native Agentic Work

> OpenAI's ChatGPT desktop app reached Linux in public preview — here's how to install it, wire up Codex, and get running on Ubuntu, Debian, or Fedora.

OpenAI's official ChatGPT desktop app landed on Linux in public preview on August 11, roughly a month after Anthropic shipped its own Claude desktop app for Linux. If you run an agentic coding workflow on a Linux box — a dev workstation, a homelab server, or a cloud VM you SSH into — this is the first time you can get the full ChatGPT + Codex desktop experience natively, rather than through the web or a terminal-only Codex CLI. Here's exactly how to get it running, straight from OpenAI's own documentation.

## What's Actually Supported

The Linux preview covers a specific, limited distro list — don't assume it'll "probably work" elsewhere without checking first:

- **Ubuntu 24.04 LTS and 26.04 LTS**
- **Debian 13**
- **Fedora 43 and 44**

Each of these has packages for both **x64** and **ARM64** architectures. OpenAI explicitly notes that other distributions "may work but aren't formally supported" — so if you're on Arch, openSUSE, or an older Ubuntu LTS, you're off the documented path.

## Step 1: Check Your Architecture

Before downloading anything, confirm which package you need:

```bash
uname -m
```

- Output `x86_64` → you need the **x64** package
- Output `aarch64` or `arm64` → you need the **ARM64** package

## Step 2: Download the Right Package

Choose based on your distro family:

| Distribution | Architecture | Package Type |
|---|---|---|
| Ubuntu or Debian | x64 | `.deb` |
| Ubuntu or Debian | ARM64 | `.deb` |
| Fedora | x64 | `.rpm` |
| Fedora | ARM64 | `.rpm` |

OpenAI hosts the actual binaries at signed URLs under `persistent.oaistatic.com` — grab the current links from the [official Linux desktop docs page](https://learn.chatgpt.com/docs/linux/linux-app) rather than hardcoding a URL here, since preview builds get updated.

## Step 3: Install on Ubuntu or Debian

```bash
cd ~/Downloads
sudo apt install ./chatgpt_amd64.deb
```

Swap in `chatgpt_arm64.deb` if you're on ARM64.

## Step 4: Install on Fedora

```bash
cd ~/Downloads
sudo dnf install ./chatgpt.x86_64.rpm
```

Swap in `chatgpt.aarch64.rpm` for ARM64.

## Step 5: Launch and Sign In

Once installed, open ChatGPT from your desktop's applications menu, or launch it directly from a terminal:

```bash
chatgpt
```

Sign in with your ChatGPT account. The app bundles ChatGPT, ChatGPT Work (if your account has it), and **Codex**, along with in-app browser workflows and support for the ChatGPT Chrome extension.

## Step 6: Keep It Updated

The installer configures OpenAI's signed package repository automatically, so future updates go through your normal package manager rather than a separate download:

```bash
# Ubuntu/Debian
sudo apt update
sudo apt install --only-upgrade chatgpt

# Fedora
sudo dnf upgrade --refresh chatgpt
```

## A Note on Wayland

If you're running a Wayland session, native Wayland support is still experimental. By default the app falls back to XWayland. To force native Wayland, fully quit the app and relaunch from a terminal with:

```bash
chatgpt --ozone-platform=wayland
```

Expect some rough edges — floating windows, window positioning, focus behavior, and keyboard shortcuts may not fully work yet under native Wayland while OpenAI continues improving support.

## What's Not Here Yet

OpenAI is upfront that some features have separate platform requirements. Notably, **Computer Use** is currently available on macOS and Windows but not in the Linux preview — OpenAI says a future release will add Linux support, without giving a firm date. If your workflow depends on Computer Use specifically, you'll need to keep using macOS or Windows for that piece in the meantime.

## Why This Matters for Agent Operators

For anyone running agentic coding loops on Linux infrastructure — CI runners, dev containers, always-on agent hosts — this closes a real gap. Previously, getting the full desktop-grade Codex experience meant either working through the browser or standing up a separate CLI-only setup. Now the same desktop app that macOS and Windows users have had is available natively, with the same Codex bundling and browser integration, on the distros most agent-operator infrastructure actually runs.
