You can run Ubuntu on your PS5 (and play Steam games)

Security engineer Andy Nguyen has released a public project enabling PS5 Phat consoles on firmware 3.xx or 4.xx to boot Linux, including Ubuntu 26.04 LTS. The ps5-linux project exploits a patched hypervisor vulnerability to give Linux direct hardware access to the PS5's Zen 2 CPU and RDNA 2 GPU. Once running, users can install Steam and play games like GTA V Enhanced at 60fps/1440p with ray tracing. The setup requires building a bootable USB image via Docker, a 64GB+ USB drive, USB ethernet/Wi-Fi adapter, and keyboard/mouse. Limitations include a 60Hz output cap, no built-in Bluetooth, and the need to re-run the exploit after each reboot since it doesn't replace the stock ProsperoOS.
