LIBEVDEV-TWEAK-DEVICE(1)     General Commands Manual	LIBEVDEV-TWEAK-DEVICE(1)

NAME
     libevdev-tweak-device - modify an evdev kernel device

SYNOPSIS
     libevdev-tweak-device  --abs ABS_X [--min a] [--max b] [--res c] [--fuzz d]
     [--flat e] /dev/input/eventX libevdev-tweak-device --resolution  res[,yres]
     /dev/input/eventX

     libevdev-tweak-device --led LED_NUML --on|--off /dev/input/eventX

DESCRIPTION
     The  libevdev-tweak-device  tool changes the properties of the evdev kernel
     device at /dev/input/eventX.  Currently this may be used to force an LED on
     or off, or to change the properties of an absolute  axis  (e.g.  its  mini-
     mum/maximum range or resolution). Changes are permanent until the device is
     removed.

OPTIONS
   Changing absolute axes
     --abs axis
	     Change  the  given  named	ABS_ kernel axis, e.g. ABS_X. For a full
	     list, see linux/input.h.  Each of the options min, max, res,  fuzz,
	     flat may be given.

     --min v
	     Set the absinfo minimum to the value v

     --max v
	     Set the absinfo maximum to the value v

     --res v
	     Set the absinfo resolution to the value v

     --fuzz v
	     Set the absinfo fuzz to the value v

     --flat v
	     Set the absinfo flat to the value v

   Changing the x/y resolution
     --resolution res[,yres]
	     Changes  the resolution of the ABS_X, ABS_MT_POSITION_X, ABS_Y, and
	     ABS_MT_POSITION_Y axis to the given resolution. If only one resolu-
	     tion value is provided, both x and y axis are set to the same reso-
	     lution, otherwise the first resolution value is applied  to  the  x
	     axes and the second value to the y axes.

   Toggling LEDs
     --led led
	     Change the given LED, e.g. LED_NUML. For a full list, see linux/in-
	     put.h.

     --on    Change the LED state to on

     --off   Change the LED state to off

NOTES
     The  kernel  does	not notify processes about absinfo property changes. Any
     process that has previously obtained the absinfo from the device  will  re-
     main  on  the old information. This makes using this tool potentially racy,
     use with caution.
