I have performed some tests with raring beta2 (linux 3.8.0-16-generic, X.Org X Server 1.13.3 - 2013-03-07 -, unity 6.12.0daily13.04.01-0ububtu1). The touch screen does not work out of the box. After the first touch it no longer responds to touches.
After installing Benjamin's kernel module (hid-multitouch-3.6+) the touchscreen works as expected most of the time. The bug "triggered 'if(!(event->device_event.flags & (1 << 5)))'" described at my very first post here, still apears from time to time while using the touch screen. I have not verified yet under what exact circumstances. I have also noticed that using the touch screen with some applications cause subsequent failure of getting a click event by tapping. E.g. In firefox tap on the search box. Then open onBoard keyboard. Try to type something in firefox search box with onBoard. After the first character firefox popups search suggestions that seem to take the focus from the text-box and no other characters are typed. After that tapping anywhere on the screen fails to produce a click. The problem may be solved by switching a couple of times between open windows/applications with alt+tab using the physical keyboard, or with logging out and in again. (Could this be related with the appearance of the bug error line in Xorg.0.log? ) The same problem exists with chromium web browser, when trying to tap on the options menu icon. The good news is that nautilus is working good with the touch screen. Double taps are correctly caught and interpreted to double clicks. After all, apart from the bug error in Xorg.0.log (can anyone tell what does it mean??) and the failure of click under the circumstances I described above, the touchscreen works fine with 13.04 at a basic level. The main problem seems to be the lack of proper multitouch suport of the main applications. Firefox does not scroll or zoom with guestures (drag n scroll pluggin can help for scrolling), the same with chromium. Evince seems to have some support for touch. I enjoyed reading a pdf with good accelerated scrolling, but no luck with zoom with pinch. Libreoffice writer is hard to use with multitouch (no scroll with drag). I have read on the web about an ubuntu version oriented to tablets that is being prepared. From what I know it is tested against samsung galaxy tablets and has released some testing images for these devices (non x86 processors). Is there any luck that we will have some of the achievements of that project coming to the desktop x86 version of ubuntu? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-evdev in Ubuntu. https://bugs.launchpad.net/bugs/1121379 Title: Multiple finger touch fails on Sony Vaio Duo 11 running Ubuntu 12.10 (N-Trig DuoSense MultiTouch) Status in “linux-image-3.5.0-030500-generic” package in Ubuntu: Confirmed Status in “xserver-xorg-input-evdev” package in Ubuntu: Confirmed Bug description: 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: [ 2530.712] (EE) BUG: triggered 'if (!(event->device_event.flags & (1 << 5)))' [ 2530.712] (EE) BUG: ../../dix/touch.c:628 in TouchConvertToPointerEvent() [ 2530.712] (EE) Non-emulating touch event [ 2530.712] (EE) [ 2530.713] (EE) Backtrace: [ 2530.713] (EE) 0: /usr/bin/X (xorg_backtrace+0x36) [0x7f261cfadb76] [ 2530.713] (EE) 1: /usr/bin/X (0x7f261ce05000+0x7dbdf) [0x7f261ce82bdf] [ 2530.713] (EE) 2: /usr/bin/X (0x7f261ce05000+0x1380b9) [0x7f261cf3d0b9] [ 2530.713] (EE) 3: /usr/bin/X (0x7f261ce05000+0x137c65) [0x7f261cf3cc65] [ 2530.714] (EE) 4: /usr/bin/X (0x7f261ce05000+0x13a5d3) [0x7f261cf3f5d3] [ 2530.714] (EE) 5: /usr/bin/X (0x7f261ce05000+0x15bc8f) [0x7f261cf60c8f] [ 2530.714] (EE) 6: /usr/bin/X (mieqProcessDeviceEvent+0x1b5) [0x7f261cf8f385] [ 2530.714] (EE) 7: /usr/bin/X (mieqProcessInputEvents+0xf8) [0x7f261cf8f4a8] [ 2530.714] (EE) 8: /usr/bin/X (ProcessInputEvents+0x9) [0x7f261ce98789] [ 2530.714] (EE) 9: /usr/bin/X (0x7f261ce05000+0x557d2) [0x7f261ce5a7d2] [ 2530.715] (EE) 10: /usr/bin/X (0x7f261ce05000+0x4456a) [0x7f261ce4956a] [ 2530.715] (EE) 11: /lib/x86_64-linux-gnu/libc.so.6 (__libc_start_main+0xed) [0x7f261adb076d] [ 2530.715] (EE) 12: /usr/bin/X (0x7f261ce05000+0x448ad) [0x7f261ce498ad] [ 2530.715] (EE) 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.
