Mainstream OS is an Arch-based Linux distribution for people who want a modern desktop without editing config files. It ships end-4's illogical-impulse Quickshell shell — heavily modified and openly credited — on Hyprland, with a full GUI settings app for monitors, theming, keybinds, networking, and updates. Pick a wallpaper and the whole OS rethemes to match; save and schedule themes.
A real distribution, not a respin: its own GPG-signed package repo (no AUR at install), signed ISOs, and a Calamares installer with five install methods including full-disk encryption and dual-boot. Every update takes a Btrfs snapshot first — one-click rollback from the boot menu — and each install runs a 19-check self-verification. Gaming Mode swaps to a SteamOS-style Big Picture session with one keypress; Console Mode boots straight into it. A legacy-NVIDIA edition covers older GPUs.
