Linux AMDGPU Control Application

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

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 application.

API

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

CLI

There is also a cli available.

• Getting basic information:

  lact cli info

  Example output:

  GPU Model: Radeon RX 570 Pulse 4GB
  GPU Vendor: Advanced Micro Devices, Inc. [AMD/ATI]
  Driver in use: amdgpu
  VBIOS Version: 113-1E3871U-O4C
  VRAM Size: 4096
  Link Speed: 8.0 GT/s PCIe
  

• Getting current GPU stats:

  lact cli metrics

  Example output:

  VRAM Usage: 545/4096MiB
  Temperature: 46°C
  Fan Speed: 785/3200RPM
  GPU Clock: 783MHz
  GPU Voltage: 0.975V
  VRAM Clock: 1750MHz
  Power Usage: 38/155W
  

• Showing the current fan curve:

  lact cli curve status

  Example output:

  Fan curve:
  20C°: 0%
  40C°: 0%
  60C°: 50%
  80C°: 88%
  100C°: 100%
  

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.
