I run Arch-based Omarchy, and some hardware doesn't care.
venusctl: a gaming mouse with no Linux support
The UtechSmart Venus MMO mouse isn't supported by the usual Linux RGB tools, and the one community tool's lighting protocol didn't work. I worked out the protocol, verified it on the hardware, and wrote a small tool around it:
venusctl.py dump # read the mouse's current state into JSON
venusctl.py apply # write the JSON back to the mouseProfiles, colors, lighting modes, brightness, DPI stages and polling rate all come from one JSON file. There are presets per game, and an auto-switcher that detects which Steam game is running and applies its profile, re-flashing the mouse only when the game changes. No GUI, no vendor software, just Python and hidapi.
k100-hwlight: keyboard protocol research
Research into the Corsair K100's Bragi HID protocol, aimed at storing lighting in the keyboard's own memory. It includes a client that probes the keyboard's properties and resources, a full backup of its onboard memory taken before any write, and a script that sets the lighting as soon as the driver loads.
The Omarchy 4.0 config port
Omarchy 4.0 moved Hyprland's configuration from .conf files to Lua. I ported my whole setup (bindings, monitors, input, look and feel, autostart) ahead of the one-way upgrade, with the original files and a package snapshot kept so it can be checked and recovered.
