Arch Linux On Sony Vaio not recognizing Touch Events Properly


I'm using Arch Linux on a Sony Vaio SVF15219 which supports touch events through an Atmel maxtouch digitizer. My problem is that, for Example, if I Want to select the close button in touchscreen I have to touch around 2 cm below it.In addition to that, In order to achieve the above Criteria I have to run `xinput set-int-prop "Atmel Atmel maXTouch Digitizer" "Evdev Axis Calibration" 32 -14 4094 180 4247` Command at startup, which is the result I obtained from Running `xinput-calibration` command.

Any Help Would Be Appreciated.

Create a config file at /usr/share/X11/xorg.conf.d/20-evdev.conf:
Code:
Section "InputDevice"
        Identifier "touchscreen catchall"
        Driver "evdev"
        Option "Calibration" "32 -14 4094 180 4247"
EndSection
According to man evdev the "Calibration" bit should only have 4 values (min-x, max-x, min-y & max-y) so I'm not entirely sure if those values will work.

I have no experience of touchscreens so this was all gleaned from man xorg.conf & man evdev -- you may have to fiddle with it a bit (in accordance with those man pages) to get it to work.

Did you try fiddling with it?

Try changing the "Identifier" to the full name of the device.

Try removing the "-14" bit from the Calibration.

Read man evdev & man xorg.conf and see if you can come up with a better config file.

You're using Arch, this requires some ability on your part or at the very least a willingness to research your issues yourself and learn new skills.

If you want a solution served up on a plate, Arch probably isn't for you.
