Linux GPU Control Application (LACT) gets a new fan control UI, automatic fan mode threshold on Nvidia

Linux GPU Control Application (LACT) is a wonderful open source app that allows you to tweak various settings for your GPU on Linux. The latest update brings some great new features, like the new fan control UI.

With the new fan control you're able to actually drag around the points, instead of using a series of sliders. It's a much nicer system, giving you fine-grained control over moving it all around to exactly where you want it. And, it just looks cool. There's also a new option in the UI to set which temperature sensor is used for the curve although they said this specific part "this only works on 6000 series and older AMD cards due to hardware limitations)".

Some of the other major changes:

• Automatic fan mode threshold on Nvidia

  Most Nvidia GPUs support turning the fan off below a certain temperature, but this only works in the automatic fan control mode. When using manual controls such as a custom fan curve in LACT, the GPU limits possible fan speeds between 30% and 100%.
  It is now possible to work around this by switching the fan control to automatic below a configured temperature, allowing the fan to turn off at lower temperatures even when using a custom curve.

• More information reporting

  There is some new information that is now reported by LACT:

  • OpenCL details, including supported versions and basic hardware properties
  • GPU instruction set version on AMD
  • ROP count on AMD

• New config API

  There is a new API for GPU configuration in the unix socket that reuses the same format as the config file.
  Thanks to this new API, the GUI will now ask confirmation for all settings (and automatically revert if not confirmed), while previously this only worked for clockspeed/voltage settings.

• Finished GUI refactor

  All UI components now use the Relm4 library to define GTK UIs. This also resolves some problems with the UI starting to lag after applying settings serveral times related to GTK signals handling in the old implementation.

The app is also now available on Flathub making it easier than ever to install.
