Great log file, thank you. Here's what happens: ... 12:43:42.951 Enter 12:43:42.952 TouchBegin (master, dev_id=2) 12:43:43.066 ButtonRelease (slave, dev_id=13) 12:43:43.067 TouchEnd (master, dev_id=2) ...
Two observations: 1) There are indeed touch events coming in, but only from the master pointer, none directly from the touch screen device 13. That's new, I haven't seen that happening before. Onboard sticks with mouse events (ButtonPress/ButtonRelease) in that case (meaning multi-touch won't be available). 2) The first ButtonPress event is missing, there's only a ButtonRelease. That's why there's no reaction to the first touch. When you use the mouse the initial ButtonPress event is there. I've looked into 1) a bit. The screen seems to be USB connected and probably uses the hid-multitouch kernel driver and the evdev X driver. Support for the SYNA7500 seems relatively sensitive to the kernel version. This thread reports mixed results with various kernels and failures in particular with Vivid's kernel 3.19: http://ubuntuforums.org/showthread.php?t=2187204&page=14&s=34cfa4caf159096f7cce745988b1ab59 If everything else fails, trying different kernels may make sense. No idea what could cause 2) yet. I'm working on some way to reproduce it. Is there anything I should know about your setup? Is this plain KWin without any other bits of KDE? Things you could try: Set Preferences->Keyboard->Advanced->"Touch input" to "none". If there's no change (likely) set Preferences->Keyboard->Advanced->"Input event source" to "GTK". -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to onboard in Ubuntu. https://bugs.launchpad.net/bugs/1470825 Title: Onboard focus with KWin Status in onboard package in Ubuntu: New Bug description: Customized Ubuntu 15.04, running KWin via an .xsession call. Using Onboard for on-screen keyboard. The keyboard won't get focus unless I tap on it twice (or unless I drag into the keyboard, and then tap it). In my previous environment I used Compiz and didn't have this behaviour, nor do I see it with any other window type. Turning debugging on for Onboard it seems to be getting the touch events so I am not sure why its not getting focus. Its output for example would be: Code: Select all 19:23:08.392 EVENT TouchInput Source device: XIDevice(id=13 attachment=2 use=3 touch_mode=1 source=GDK_SOURCE_TOUCHSCREEN name=SYNA7500:00 06CB:3AF0 vendor=0x06cb product=0x3af0 enabled=1) 19:23:08.392 EVENT TouchInput _on_device_event1 19:23:08.393 EVENT TouchInput _on_device_event2 2 2 19:23:08.393 EVENT TouchInput _on_device_event7 1 19:23:08.393 EVENT TouchInput _on_device_event8 True 19:23:08.393 EVENT TouchInput _on_device_event10 20971528 20971707 19:23:08.393 EVENT TouchInput _on_device_event11 19:23:08.394 EVENT TouchInput Device event: dev_id=2 src_id=2 xi_type=7 xid_event=20971528(20971707) x=171.0 y=45.0 x_root=1642.0 y_root=405.0 button=0 state=0 sequence=0 A little lost and looking for any suggestions!
