HoloISO: Ground zero

on GitHub

This is the first beta release for HoloISO! And the first actual SteamOS 3 ISO to be available online (maybe!)
This installs full (almost) SteamOS 3, including holo and jupiter repositories with their mirror, new Big Picture session, Valve's forks of MESA/Vulkan

Working:

• Boots
• Deck UI (separate session)
• Deck UI (-gamepadui)
• TDP/FPS limiting
• Global FSR
• Shader Pre-Caching
• cool-looking neofetch?
• SteamDeck pacman mirrors

Known issues:

• While Big Picture works, you might get stuck on "Network setup" screen due to mismatched execution permissions, to fix this, just run sudo chmod +x /usr/bin/steamos-update /usr/bin/steamos-session-select in desktop mode
• On AMD GPUs, for some reason vulkan binaries don't get installed, just install vulkan-radeonand lib32-vulkan-radeon if you encounter this issue
• KDE defaults desktop theme to light mode for now
