Hi,
I'm having a Viewsonic Viewpad 10 (
http://www.viewsonic.com/products/vpad10.htm ) in front of me, and am trying
to get Plasma Tablet running on it. It's a 10 inch Atom-based Tablet PC,
pretty nice hardware and Plasma runs smoothly on it. I've one major problem,
though:
While the touchpad works in principle, it sends way too many click events,
even on light taps, the effect: you tap lightly on one button (for example on
the virtual keyboard), and the corresponding letter turns up 10 times. Also
flicking doesn't work, since that is quite strict about the number and order
or events received.
I've tried to poke through Xorg and XInput2, but couldn't find any handle to
make the touchpad not go nuts. It's a Hanvon touchscreen, and apparently using
the evdev driver. I've tried the "evtouch" driver as well, but that one would
completely screw up directions, so overall completely unusable instead of just
"unable to click or flick".
Attached the output of xinput list and list-props for this device. I'm a big
n00b in that area though, so I'd appreciate any help with this.
So, where are the input-knowledgable people here? :-)
Thanks for your input (ha!),
