我有一台 Lenovo Yoga 2 11" 可变形笔记本电脑,它有一个触摸屏,xinput 告诉我的是:
> xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ETPS/2 Elantech Touchpad id=13 [slave pointer (2)]
⎜ ↳ Atmel Atmel maXTouch Digitizer id=10 [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)]
↳ Lenovo EasyCamera id=9 [slave keyboard (3)]
↳ Ideapad extra buttons id=11 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)]
(它是“Atmel Atmel maXTouch 数字化仪”)。它在 Ubuntu 和 Fedora 中运行良好,但在 Arch Linux 中,触摸屏就像鼠标一样。它有一个指针,但无法识别多点触控。我怎样才能让它发挥作用?
