DS Tuner is a DualSense controller raw input modifier. It modifies the data received from the controller even before it reaches the driver via HID-BPF, so it works in every context (even hidraw).

Currently you can adjust:

• Analog stick deadzone
• Trigger deadzone

Full list of options can be found in ds-tuner.toml.

Currently only the base DualSense controller is supported since it's the only one I own, but other Sony controllers could be supported supported as well with minimal changes. (PRs welcome)

Can be used either manually or as a systemd service. The configuration file will be hotreloaded upon change.

Install it with cargo.

cargo install ds-tuner

Then run execuatable as root. Optionally specify the config file to use.

sudo ds-tuner start --config <path to your config file>

The config path defaults to ds-tuner.toml in the current working directory.

Example instructions to install it can be found in PKGBUILD.
