Eu tenho um thinkpad X230T com tela multitoque, e o ubuntu trata entradas multitoque como apenas 'cliques'.
aqui está minha saída de xinputs:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Wacom ISDv4 E6 Pen stylus id=10 [slave pointer (2)]
⎜ ↳ Wacom ISDv4 E6 Finger touch id=11 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=13 [slave pointer (2)]
⎜ ↳ TPPS/2 IBM TrackPoint id=14 [slave pointer (2)]
⎜ ↳ Wacom ISDv4 E6 Pen eraser id=16 [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)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ Integrated Camera id=9 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)]
↳ ThinkPad Extra Buttons id=15 [slave keyboard (3)]
(minha última tentativa de fazê-lo funcionar (apenas 10 minutos atrás) foi atualizado para o Ubuntu 17.04.)
Alguma sugestão para fazer o Ubuntu reconhecer touch-screen como eventos de toque?
ps: os sintomas podem ser verificados usando o aplicativo de demonstração multi-toque qt e o Google Chrome ...
