Introduce inhibit subcommand to prevent system sleep while tasks run, offering flexible daemon and why options. - New Features - Added inhibit.rs module with `lapctl inhibit`, `lapctl inhibit --daemon`, and `lapctl inhibit --why "..."`. - Updated README.md with detailed Sleep Inhibitor description and usage examples. - Enhancements - Added Sleep inhibitor entry to the project checklist under Tool configuration saving. - Included inhibit.rs in the project structure listing. - Improved CLI help context for power and cooling sections. - Bug Fixes - No bug fixes included in this change.
lapctl
lapctl is a fast and easy command line tool made in Rust. It helps you control your Linux laptop hardware from the terminal.
You can use it to change your graphics card mode, set battery charge limits, pick power profiles, and control the cooling fans. It talks directly to your system hardware, so it does not need any heavy background programs to run.
What It Can Do
Graphics Control
Easily switch between Integrated, Nvidia, and Hybrid graphics modes to save battery or get more power.
Battery Health
Set a battery charge limit like 80% to make your battery last longer over the years.
Power Saving
Change power profiles and set CPU power limits to save energy when you need it.
Cooling Control
Control the cooling fans for laptops like Lenovo or ASUS to keep your computer quiet or cool.
Sleep Inhibitor
Prevent your system from sleeping or suspending while running a task or indefinitely.
Hardware Status
Check the status of your battery, graphics, and power all in one place.
