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!!!
