Guide: Ubuntu 24.04 + XFCE on Meta Quest 2 via Termux & VNC (with Tailscale & Firefox ESR)

Date: Tuesday, April 15, 2025 at 10:20:59 PM KST

This guide details the steps to set up the Quest 2 host environment and then install Ubuntu (expected to be 24.04 LTS) with the XFCE4 desktop environment inside Termux on a Meta Quest 2 headset. Access to the graphical desktop is achieved using a VNC client connecting over a Tailscale secure network. It includes instructions for Firefox ESR and Korean language support.

Disclaimer:

• Performance: Expect sluggish performance compared to a native PC setup. This runs via compatibility layers (proot) within Android. Firefox ESR, while stable, can still be demanding.
• Usability: Interacting with a desktop UI in VR can be challenging. A Bluetooth keyboard and mouse connected to the Quest 2 are highly recommended.
• Third-Party Software: This guide involves SideQuest and, optionally, APKPure. Use third-party sources and sideloading responsibly and at y
