jstest-gtk - joystick testing and configuration tool


jstest-gtk [options]... [device] files...


jstest-gtk is a simple joystick tester based on Gtk+. It provides a list of attached
joysticks, a way to display which buttons and axis are pressed, a way to remap axis and
buttons and a way to calibrate your joystick.

Even when your joystick is working mostly fine, you might want to give it a try, as the
calibration lets you get rid of overlarge default deadzones that many joysticks use and
then is a noticeable problem in some games.


jstest-gtk is mainly a graphical interface to check that your joysticks and pads work
properly. You can find precise information on each axis, you can optionally recalibrate it
and also change the mapping.

If you run the program without parameters, you will get a window showing all the joystick
devices in your system (there can be more than one). When you double click on one of them,
you will get a newer window with detailed information about its axis and buttons.

There are two buttons in the detailed window called "Mapping" adn "Calibration", that
allows you to reconfigurate the device.

If you run the program with a device as an argument (for example /dev/input/js0), you will
get the detailed window for that device directly, without getting the whole list of
joysticks in the system.

Calibration of the axis consists in a simple window in which you set the values that go
directly into the operative system configuration, without doing any changes on them.
They're divided in range and dead zone (or center). In both of them you have to set a
minimum and a maximum. You also have a checkbox for inverting the axis.

Values are changed and applied in the same instant that you modify them, there's no need
for clicking anywhere or doing anything else for applying the changes.


These program follows the usual GNU command line syntax, with long options starting with
two dashes (`-').
