Codex VS Code extension hangs on Linux when VS Code is launched from the desktop entry
A GitHub issue against openai/codex says the Codex VS Code extension often never finishes initializing when VS Code is started from the official Linux desktop launcher.
Symptoms
- The Codex panel stays on the loading screen.
- Logs stop after Initialize received id=1.
- There is no visible error, timeout, retry, or recovery path.
Reproduction clue
- Launching the same VS Code install and workspace from a terminal with code . makes Codex initialize normally.
- The issue was reproduced on multiple Linux desktops/distros.
This points to an environment difference between GUI launch and terminal launch that breaks app-server initialization.
