Public bug reported:
N-trig DuoSense multitouch screen on Sony Vaio Duo 11 (model
SVD1121P2EB) ultrabook/tablet hybrid does not function as expected 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
appended to Xorg.0.log:
(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.
