legionlinuxtui

Terminal UI for controlling Lenovo Legion laptops on Linux

TLDR

Run the TUI (needs root for sysfs/driver I/O)

$ sudo legionlinuxtui

Build from source and run

$ go build -o build/

$ sudo ./build/legionlinuxtui

Run without installing (from a checkout)

$ sudo go run .

legionlinuxtui is a terminal user interface for Lenovo Legion laptops on Linux. It reads sensor data and exposes capability toggles (for example conservative mode and power mode) through a full-screen TUI, refreshing sensor information about every 100 ms.It depends on the community Lenovo Legion Linux kernel drivers (sysfs interfaces) and on lm_sensors being set up correctly on the machine. The process needs elevated privileges to talk to drivers and write sysfs values — invoke with sudo (or equivalent).Written in Go. Packaging is available via Nix (NUR / flake packages from the author); otherwise build with Go ≥ 1.24.4 from the repository.

PARAMETERS

No command-line options are required. Launch the binary; interaction is entirely through the TUI.

CAVEATS

Requires Lenovo Legion hardware supported by [LenovoLegionLinux](https://github.com/johnfanv2/LenovoLegionLinux) drivers, plus a working sensors setup. Must run with privileges sufficient for driver/sysfs I/O. Not a generic laptop control tool for non-Legion machines.
