我在 Acer A315-51-54AP 上安装了 Ubuntu 20.04，该设备配有 ETPS/2 Elantech 触控板和 synaptics 驱动程序。正如标题所述，物理点击按钮不起作用，而点击按钮起作用（这要归功于 synaptics 驱动程序）。这是我的xinput

从功能部分来看，它确实有一个物理左键，没有物理右键。然而，它们都不起作用。我读过一些帖子，例如触摸板右键无法识别但那里的解决方案不起作用。我还读过在 grub 中添加一些涉及 i8042 的内核参数这里，但我不知道我可以使用哪一个。最后，我尝试添加内核参数，psmouse.elantech_smbus=0但没有变化。此外，这是我70-synaptics.conf的/etc/X11/xorg.conf.d/
