hey, i have a question, again, maybe someone can help me. i applied the patch into the ubuntu evtouch package, i am using lucid 64bit. the laptop is a acer 1820pt, if understand it right is has the same hardware as the 1420p.
 
afterwards the pointer not longer jumps to the left corner. it moves on the x-axis exactly in the middle of the y-axis. the movement on the x-axis isn't proportional, if i am at the middle the pointer goes of the screen. i guess it is a calibration problem, but i am not able to solve it myself.

the xinput_calibrator gives me the following information:
Calibrating standard Xorg driver "EVTouch TouchScreen"
	current calibration values: min_x=0, max_x=1366 and min_y=0, max_y=768
	If these values are estimated wrong, either supply it manually with the --precalib option, or run the 'get_precalib.sh' script to automatically get it (through HAL).


== Applying the calibration ==
There are multiple ways to do this: the tranditional way (xorg.conf), the new way (udev rule) and the soon deprecated way (HAL policy):

xorg.conf: edit /etc/X11/xorg.conf and add in the 'Section "InputDevice"' of your device:
	Option	"MinX"		"328"
	Option	"MaxX"		"1513"
	Option	"MinY"		"384"
	Option	"MaxY"		"384"

udev rule: create the file '/etc/udev/rules.d/99_touchscreen.rules' with: (replace %Name_Of_TouchScreen% appropriately)
	ACTION!="add|change", GOTO="xorg_touchscreen_end"
	KERNEL!="event*", GOTO="xorg_touchscreen_end"
	ATTRS{product}!="%Name_Of_TouchScreen%", GOTO="xorg_touchscreen_end"
	ENV{x11_options.minx}="328"
	ENV{x11_options.maxx}="1513"
	ENV{x11_options.miny}="384"
	ENV{x11_options.maxy}="384"
	LABEL="xorg_touchscreen_end"

HAL policy: create the file '/etc/hal/fdi/policy/touchscreen.fdi' with: (replace %Name_Of_TouchScreen% appropriately)
	<match key="info.product" contains="%Name_Of_TouchScreen%">
	  <merge key="input.x11_options.minx" type="string">328</merge>
	  <merge key="input.x11_options.maxx" type="string">1513</merge>
	  <merge key="input.x11_options.miny" type="string">384</merge>
	  <merge key="input.x11_options.maxy" type="string">384</merge>
	</match>

the calibration script of the package does not seem to help. i tried to
manually change the values in the different files, but it doesn't change
anything.

i guess i am a little bit out of my league here, in matters of my
knowledge. i am going to attach some files. if someone could help me i
would be very thankful!!!
