Linux AMDGPU Control Application

This application allows you to control your AMD GPU on a Linux system.

GPU info	Overclocking	Fan control

Current features:

• Viewing information about the GPU
• Power/thermals monitoring
• Fan curve control
• Basic overclocking

Currently missing:

• Precise clock/voltage curve manipulation (currently can only set the maximum values)

Installation

• Arch Linux: Install the AUR Package (or the -git version)

• Debian/Ubuntu/Derevatives: Download a .deb from releases.

  It is only available on Debian 12+ and Ubuntu 22.04+ as older versions don't ship gtk4.

• Fedora: an rpm is available in releases.

• Otherwise, build from source.

Why is there no AppImage/Flatpak/other universal format? See here.

Configuration

There is a configuration file available in /etc/lact/config.yaml. Most of the settings are accessible through the GUI, but some of them may be useful to be edited manually (like admin_groups to specify who has access to the daemon)

Building from source

Dependencies:

• rust
• gtk4
• pkg-config
• make
• hwdata

Steps:

• git clone https://github.com/ilya-zlobintsev/LACT && cd LACT
• make
• sudo make install

Usage

Enable and start the service (otherwise you won't be able to change any settings):

sudo systemctl enable --now lactd

You can now use the GUI to change settings and view information.

API

There is an API available over a unix socket. See here for more information.

CLI

There is also a cli available.

• List system GPUs:

  lact cli list-gpus

  Example output:

  1002:687F-1043:0555-0000:0b:00.0 (Vega 10 XL/XT [Radeon RX Vega 56/64])
  

• Getting GPU information:

  lact cli info

  Example output:

  lact cli info
  GPU Vendor: Advanced Micro Devices, Inc. [AMD/ATI]
  GPU Model: Vega 10 XL/XT [Radeon RX Vega 56/64]
  Driver in use: amdgpu
  VBIOS version: 115-D050PIL-100
  Link: LinkInfo { current_width: Some("16"), current_speed: Some("8.0 GT/s PCIe"), max_width: Some("16"), max_speed: Some("8.0 GT/s PCIe") }
  

The functionality of the CLI is quite limited. If you want to integrate LACT with some application/script, you should use the API instead.

Reporting issues

When reporting issues, please include your system info and GPU model.

If there's a crash, run lact gui from the command line to get logs, or use journalctl -u lactd to see if the daemon crashed.

Alternatives

If LACT doesn't do what you want, make sure to check out CoreCtrl.
