16 libinput uses the kernel ``fuzz`` value to determine the size of the
26 libinput provides the debugging tool ``libinput measure fuzz`` to help edit or
27 test a fuzz value. This tool is interactive and provides a udev hwdb entry
28 that matches the device. To check if a fuzz is currently present, simply run
34      $ sudo libinput measure fuzz
40 In the above output, the axis fuzz is set to 16. To set a specific fuzz, run
41 with the ``--fuzz=<value>`` argument.
46      $ sudo libinput measure fuzz --fuzz=8
59 Below is the outline of what a user needs to do to override a device's fuzz
60 value in case the ``libinput measure fuzz`` tool fails.
69 ``EVDEV_ABS_00=min:max:resolution:fuzz``. You need to set the ``fuzz`` part,
71 property that only sets resolution and fuzz reads as ``EVDEV_ABS_00=::32:8``.
85 ``libinput measure fuzz`` and the DMI match content with your hardware. See
90 "libinput record" should show the new fuzz value for the axes.
92 Restart the host and libinput should pick up the revised fuzz values.
97 Kernel fuzz
100 A fuzz set on an absolute axis in the kernel causes the kernel to apply
102 inconsistent deltas. To avoid this, libinput sets the kernel fuzz on the
103 device to 0 to disable this kernel behavior but remembers what the fuzz was
104 on startup. The fuzz is stored in the ``LIBINPUT_FUZZ_XX`` udev property, on
