Bug Description
I have a HP Pavilion x360 convertible 15 br0xx. This laptop has a multitouch touchscreen and an active pen/stylus.
On ubuntu 16.04, the touchscreen used with fingers and the pen/stylus work properly. The touchscreen was identified as «ELAN0732:00 04F3:24B8» as slave pointer and the pen as «ELAN0732:00 04F3:24B8 Pen» as slave pointer too.
But, on ubuntu 18.04 bionic with gnome shell, the pen/stylus is identified «ELAN0732:00 04F3:24B8 Pen» as slave keyboard instead as slave pointer. Touchscreen work well until pen/stylus is used. At this point, a new device «ELAN0732:00 04F3:24B8 Pen Pen (0)» is enabled. The touchscreen stops working and the pen/styles works but with some issues.
~$ xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ETPS/2 Elantech Touchpad id=15 [slave pointer (2)]
⎜ ↳ ELAN0732:00 04F3:24B8 id=10 [slave pointer (2)]
⎜ ↳ ELAN0732:00 04F3:24B8 Pen Pen (0) id=18 [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)]
↳ HP Wide Vision HD Camera: HP Wi id=9 [slave keyboard (3)]
↳ Intel Virtual Button driver id=12 [slave keyboard (3)]
↳ Intel Virtual Button driver id=13 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=14 [slave keyboard (3)]
↳ HP WMI hotkeys id=16 [slave keyboard (3)]
↳ HP Wireless hotkeys id=17 [slave keyboard (3)]
↳ ELAN0732:00 04F3:24B8 Pen id=11 [slave keyboard (3)]
After disable devices id=11 and id=18, touchscreen recovers its multitouch feature.
There is no combination enabling/disabling ids 10, 11 and 18, to get multitouch and pen working together.
On Wayland session, I get the same behavior.
Note: Ubuntu 18.04 LTS clean installation with «minimal install option» and no other customization.
By disabling the Gesture parameter for my touchscreen multitouch is working. But no more pinch to zoom or to finger to scroll ... no more Gestures !
Both should be able to work together.
Should I open an issue ?
