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.
