+Ignore the specified type of axis. Default: unset. The X server cannot deal
with devices that have both relative and absolute axes. Evdev tries to guess
wich axes to ignore given the device type and disables absolute axes for
mice and relative axes for tablets, touchscreens and touchpad. These options
allow to forcibly disable an axis type. Mouse wheel axes are exempt and will
work even if relative axes are ignored. No property, this configuration must
be set in the configuration.
+.br
+If either option is set to False, the driver will not ignore the specified
+axes regardless of the presence of other axes. This may trigger buggy
+behavior and events from this axis are always forwarded. Users are
+discouraged from setting this option.
