z13gui

GTK4 overlay drawer for z13ctl on Wayland — graphical controls for the 2025 ASUS ROG Flow Z13 on Linux.

What z13gui does

Profile switching — quiet, balanced, performance, and custom TDP profiles
Custom TDP control — configurable power limits (PL1/PL2/PL3) in the custom profile view, with basic and advanced modes
Fan curve editor — per-profile fan response curve editing (custom profile, advanced mode)
Undervolt — CPU Curve Optimizer offset (requires ryzen_smu kernel module; iGPU CO is not supported on Strix Halo)
APU telemetry — live temperature and fan RPM readouts in the custom profile view
Battery charge limit — set the charge cap (40–100%) from the drawer
RGB lighting — mode, color, speed, and brightness for the keyboard backlight and edge lightbar
System toggles — panel overdrive and boot sound on/off
Theme picker — 15 built-in themes with full custom theme support
Gamepad navigation — full D-pad + button control for Steam Gaming Mode

All hardware communication goes through the z13ctl daemon. z13gui never touches HID devices or sysfs directly.

Two backends are supported, selected automatically based on the session environment:

Layer-shell (KDE Plasma, Hyprland, Sway) — Wayland layer-shell overlay with margin-based slide animation and focus-loss dismiss
Gamescope (Steam Gaming Mode) — X11 overlay via the STEAM_OVERLAY atom with opacity-based visibility and a click-to-dismiss backdrop

Wayland compositor with layer-shell support, or gamescope (Steam Gaming Mode)
GTK 4 and gtk4-layer-shell libraries (see Installation for distro package names)
