Touchscreen issues: jumpy cursor

[Jaydee]

Many thanks for your work on both th plpevtch driver and Flybook
Ubuntu ISO. I am using the latest (0.4) Ubuntu ISO on my Dialogue
Flybook V33i, And I have run into an issue that has plagued me in the
past.

It seems that, even after following your instructions on calibration
of the , my cursor jumps around by roughly 50 pixels, even when the
stylus is held perfectly still against the screen. This "jumpiness"
makes the touchscreen all but unusable.

Have you run into this issue? Could it be calibration related?

(included in the files section of this group are my dmesg, xorg.conf
and Xorg.0.log outputs)

please do the following

activate calibration in xorg.conf
restart the flybook
when the xserver runs press only 1 time for a few seconds still the
same position on the touchsceen (that the cursor jumps around)
then post again dmesg and Xorg.0.log

only one press is required to see what part reports the different
position infos
