我在带有 Elantech 触摸板的 hp pavilion ab048tx 上运行 ubuntu gnome 16.04.1。我尝试过互联网上提供的各种 dkms 修复程序（包括 psmouse-elantech-x551c 和 psmouse-elantech-v7），但似乎没有任何方法可以使多点触控发挥作用。基本功能有效（移动、单击、点击和右键单击）。知道该怎么做吗？
我的（部分）猫输出/proc/总线/输入/设备如下：
I: Bus=0011 Vendor=0002 Product=0001 Version=0000
N: Name="PS/2 Elantech Touchpad"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input5
U: Uniq=
H: Handlers=mouse0 event6
B: PROP=1
B: EV=7
B: KEY=70000 0 0 0 0
B: REL=3
对于 demsg | grep elantech，它是：

我尝试使用 modprobe psmouse proto=imps 但它被检测为 PS/2 通用鼠标并且仍然没有任何反应。evdev 目前正在处理触摸板，我也尝试使用 libinput，但它不起作用。
如果我尝试强制使用“synaptics”驱动程序/usr/share/X11/xorg.conf.d，触摸板将完全停止工作
编辑：我的设备有触摸屏（检测为 Radiyum）
如果需要请询问更多！
