DESCRIPTION
       egalax is an Xorg input driver for eGalax touchscreen devices...

       The  egalax driver functions as a pointer input device, and may be used
       as the X	server's core pointer.

       It is obvious that a touch panel	with a stylus/finger is	 a  one-button
       mouse.	However,  the  egalax tries to overcome	this limitation.  If a
       user keeps stylus in one	point for a certain time, then driver emulates
       release	of left	mouse button and then pressure on the right mouse but-
       ton.  The area where the	stylus should be kept  and  time  are  config-
       urable.

SUPPORTED HARDWARE
       The driver has been written for CarTFT CTF1020-S	on screen touch	panel,
       and is supposed to work	with  other  similar  touch  panels  based  on
       eGalax.

       The egalax driver requires the uep(4) kernel driver.

CONFIGURATION DETAILS
       The following driver Options are	supported:

       Option "Device" "string"
	      Usually "/dev/uep0" .

       Option "MinX" "integer"

       Option "MaxX" "integer"

       Option "MinY" "integer"

       Option "MaxY" "integer"
	      These values configure calibration of the	touch panel.

	      The  touchscreen	resolution  is 2048 points in both directions.
	      However, the onscreen part of the	panel is usually smaller.  So,
	      the  panel  needs	to be calibrated.  Initial values for calibra-
	      tion are quite conservative, and the driver  autocalibrates  it-
	      self  when  user	touches	areas near edge	of screen.  After each
	      autocalibration the driver writes	suggested  calibration	values
	      to  the  Xorg  log.   These values should	be written to the Xorg
	      configuration file, to avoid bad calibration on next run.

       Option "ReverseY" "boolean"
	      Invert the Y axis.  Default: off.

       Option "SwapAxes" "boolean"
	      Some eGalax touch	screen units  are  assembled  incorrectly  and
	      have  X  and  Y axes swapped.  This configuration	knob allows to
	      swap them	back.  Default:	off.

       Option "RightClickEmulArea" "integer"
	      Size of the area where a stylus should be	held still, before the
	      driver emulates right button click.  The default is 5 pixels.

       Option "RightClickEmulPause" "integer"
	      Time  the	 driver	 waits	befor emulating	right button pressure.
	      The default is 1 second.
