GNOME下触摸板设置

触摸板因为一直不能轻触很难受，查了一下。

Touchpad not working in GNOME
Ensure the touchpad events are being sent to the GNOME desktop by running the following command:

$ gsettings set org.gnome.desktop.peripherals.touchpad send-events enabled

Additionally, GNOME may override certain behaviors, like turning off Tapping and forcing Natural Scrolling. In this case the settings must be adapted using GNOMEs gsettings command line tool or a graphical frontend of your choice. For example if you wish to enable Tapping and disable Natural Scrolling for your user, adjust the touchpad key-values like the following:

$ gsettings set org.gnome.desktop.peripherals.touchpad tap-to-click true

$ gsettings set org.gnome.desktop.peripherals.touchpad natural-scroll false

（作为参考，这里笔者只修改了tap-to-click属性）
