Public bug reported: Hi,
I asked a question here https://answers.launchpad.net/ubuntu/+source/xinput/+question/668859 but no one seems to answer... So I try here I can't make multitouch work with my yoga 720 convertible. At least not as expected. The touchscreen work, some gestures work but touchscreen is not able to handle multiple touch event unless I disable Gesture parameter. xinput --list Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Wacom HID 50F1 Finger touch id=12 [slave pointer (2)] ⎜ ↳ MSFT0001:02 06CB:7F8F Touchpad id=10 [slave pointer (2)] ⎜ ↳ Wacom HID 50F1 Pen stylus id=11 [slave pointer (2)] ⎜ ↳ Wacom HID 50F1 Pen eraser id=15 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Power Button id=8 [slave keyboard (3)] ↳ EasyCamera: EasyCamera id=9 [slave keyboard (3)] ↳ Ideapad extra buttons id=13 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=14 [slave keyboard (3)] xinput --test 12 motion a[0]=8021 a[1]=5619 a[2]=0 a[3]=0 a[4]=0 a[5]=0 button press 1 a[0]=8021 a[1]=5619 a[2]=0 a[3]=0 a[4]=0 a[5]=0 button release 1 motion a[0]=8523 a[1]=5587 a[2]=0 a[3]=0 a[4]=0 a[5]=0 button press 1 a[0]=8523 a[1]=5587 a[2]=0 a[3]=0 a[4]=0 a[5]=0 button release 1 motion a[0]=8405 a[1]=4306 a[2]=0 a[3]=0 a[4]=0 a[5]=0 button press 1 a[0]=8405 a[1]=4306 a[2]=0 a[3]=0 a[4]=0 a[5]=0 motion a[0]=8399 a[1]=4313 a[2]=0 a[3]=0 a[4]=0 a[5]=0 button release 1 motion a[0]=7432 a[1]=5321 a[2]=0 a[3]=0 a[4]=0 a[5]=0 button press 1 a[0]=7432 a[1]=5321 a[2]=0 a[3]=0 a[4]=0 a[5]=0 button release 1 motion a[0]=7500 a[1]=5522 a[2]=0 a[3]=0 a[4]=0 a[5]=0 button press 1 a[0]=7500 a[1]=5522 a[2]=0 a[3]=0 a[4]=0 a[5]=0 button release 1 # keep one finger pressed and press another area button press 3 button release 3 I work with ubuntu 18.04 / Xorg / xinput. Prior to this version I was working with 17.10 / wayland. On 17.10 in order to make multitouch support more than 2 fingers at once I had to disable gnome gestures. Unfortunately, this is not working on ubuntu 18.04. So I found a parameter for my touchscreen called Gesture (Gesture - Turns on/off multi-touch gesture events (default is on).) By disabling this parameter for my touchscreen, multitouch is working as expected. But no more ... Gestures ! I think both should work together ** Affects: xinput (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xinput in Ubuntu. https://bugs.launchpad.net/bugs/1772637 Title: Yoga 720 touchscreen multitouch Status in xinput package in Ubuntu: New Bug description: Hi, I asked a question here https://answers.launchpad.net/ubuntu/+source/xinput/+question/668859 but no one seems to answer...
