I have followed these instructions, but have noted a few problems in addition the multitouch issue already mentioned: 1. After rebooting into Windows 8, touch NO LONGER WORKS. I tried shutting down and rebooting several times with the same result. It continues to work (for single touch) in Ubuntu. 2. The stylus does not work. It does not seem to be recognized as a wacom device. The stylus does work in Windows 8. 3. Double-tapping does not seem to result in a double-click. 4. The instructions for setting up kernel builds needs a few more uses of "sudo"
I have noticed flakey behaviour before in Windows related to touch being automatically disabled when the stylus is used then not getting reenabled afterwards. I don't know if that is relevant, since in that case it is fixed by rebooting Windows. I'm wondering if the driver is leaving the hardware in an inconsistent state when shutting down and then Windows is unable to reinitialize it. Either way, rebooting does not seem to reset the issue. -- 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.
