Run the Real ChatGPT Desktop App on Ubuntu Linux (Not a Wrapper)

Run the Real ChatGPT Desktop App on Ubuntu Linux (Not a Wrapper) TL;DR: OpenAI ships a Windows MSIX binary. You can unpack it, patch three platform assumptions, and run the actual official app natively on Ubuntu — same binary Windows users get. No Electron wrapper, no web view in a box. The Problem With Every Other Guide Search "ChatGPT desktop Ubuntu" and you'll find two things: Articles pointing you at lencx/ChatGPT — a third-party Electron wrapper that loads chatgpt.com in a window. It's not the real app. Articles pointing you at other wrappers doing the same thing. These work, but you're getting a community-built shell around a website — not the app itself. The real ChatGPT Desktop (the one in the Windows Store) has features, update hooks, and auth flows that wrapper apps can't replicate cleanly. This guide unpacks the official binary and runs it on Ubuntu 26.04. Tested on kernel 7.0.0, RTX 5070, NVIDIA 580/CUDA 13.0, both X11 and Wayland via XWayland. What the Script Actually Does
