with ubuntu 12.10.
How to reproduce the bug:
1. Boot up Sony Vaio Duo 11 to Ubuntu 12.10 and login to untiy
2. Use mouse/trackpad to Open a nautiuls window
3. Use a mouse/trackpad to Open a terminal window and run "tail -f
/var/log/Xorg.0.log"
4. With the focus to the terminal window touch inside nautilus window with
one finger. Nautilus window takes focus, as expected. Nothing is appended to
Xorg.0.log.
5. Touch with one finger inside terminal window. The terminal window takes
the focus, as expected. Nothing is appended to Xorg.0.log.
6. Touch with one finger inside nautilus window and do a drag gesture. A
rectangle select area follows hand's move. Nothing is appended to Xorg.0.log.
7. Touch again with one finger inside nautilus window and and do a drag
gesture. Nautilus window is scrolling up and down, as expected.
8. Touch with 2 fingers into nautilus window. The following Error line is

(EE) [dix] N-trig DuoSense: unable to find touch point 1
9. Do any gesture with the two fingers (eg. spread). The following
error lines are repeated during the gesture:

10. Touch with one finger an other window. Focus is not transfered to the
touched window. Expected behavior: The focus should be transfered to the
touched window.
11. Touch with one finger inside nautilus window and do a drag gesture.
Window is scrolling up and down and the above error lines are repeated at
Xorg.0.log. Expected behavior: No error messages should be generated.
12. Remove the finger from the screen and move the mouse around the screen.
Nautilus window is scrolling according to mouse movement. Expected behavior: no
scrolling should happen at nautilus window.
13. Click with the mouse inside nautilus window. The rectangle selector
appears and follows mouse movement. Expected behavior: A single click should
not trigger the rectangle selector.
After these steps mouse and touch have a strange and unstable
behavior: Mouse movement erroneously selects text without holding down
the mouse button, clicks and touches at windows do not give focus,
clicks and touches to buttons to not cause a press event, alt+tab is
not functioning.
Touching with more fingers (3 or 4) produces a similar error with
point number varying from 0 to 3 (e.g. (EE) [dix] N-trig DuoSense:
unable to find touch point 2), and after that any gesture fails
producing the above error messages.
I attach:
* geistest output
* lsb_release -a output
* lshw output
* lsinput output
* lspci -vnvn output
* mtdev-test output
* ntrig-calibrator output
* uname -a output
* cat /proc/version_signature output
* Xorg.0.log
I can perform any testing and reporting on Sony VAIO Duo 11 device. I
have quite advanced technical skills on ubuntu, compiling, config
files e.t.c. I would appreciate any guidance in order to investigate
and finally solve this bug.
