Hello,
I've just acquired an Atom tablet PC with a 10.1-inch touchscreen. The
screen appear to be a USB HID device, showing up in lsusb as
Bus 005 Device 002: ID 03eb:201c Atmel Corp. at90usbkey sample
firmware (HID mouse)
with manufacturer, product as "CDT", "10.1" in its sysfs entry. Please
find the output of report.py included at the end of this e-mail.
What I find is that attempting to use it in X, at a first attempt after
the machine is started or after resume from suspend-to-RAM, quickly
hoses the desktop: the cursor moves around, but clicks are obstructed
--- even those from other pointing devices. I then kill X via another
VT, which results in something less troublesome, but still not really
useful. In this state, monitoring with xinput test:
- dragging one finger over the screen produces a slew of items of
the form
motion <co-ordinates>
button press 1
button release 1
- a single "tap" can produce a bunch of events like this, resulting
in an inability to sensibly click or double-click
- *BUT* holding one finger on the screen and then dragging with the
other gives something like
button press 1
motion <co-ordinates>
.
.
button release 1
(sometimes there are multiple press/releases at the end). This
*sometimes* results in click-and-drag behaviour.
- Seen a few sporadic "phantom" taps in a certain region of the screen.
(Consequently, I normally float this device.) In the Xorg log, there's
the following:
[ 27.229] (II) config/udev: Adding input device CDT 10.1
(/dev/input/event5)
[ 27.229] (**) CDT 10.1 : Applying InputClass "evdev tablet

Apologies for the length of this post, but I hope it's of some use. Let
me know if any more info would be helpful.
Thanks,
James.
