如何禁用触摸板的部分功能？

我有一台 MSI 笔记本电脑，它的触摸板太宽了。我的右手有一部分放在触摸板上，当我的手摩擦触摸板时，我经常会不小心移动光标。这让我抓狂。

我想禁用触摸板的右边缘。我已经使用了 Gnome Tweaks 中的“键入时禁用触摸板”功能，但这并不能解决问题，因为在我开始键入之前，我的手会摩擦触摸板，从而移动光标。我尝试了您可以禁用触摸板的一部分吗？，但我不相信我的系统使用 Synaptics 驱动程序。

我最终将触摸板驱动程序从 libinput 换成了 synaptics。Synaptics 具有 libinput 所缺乏的许多功能，其中之一就是禁用触摸板的某个部分。微调“键入时禁用触摸板”的时间间隔也是 Synaptics 的一项有用功能。

#disabling right part of touchpad

#install synaptics drivers
sudo apt install xserver-xorg-input-synaptics
reboot
xinput list-props "PNP0C50:00 06CB:CDAA Touchpad"
xinput list-props "PNP0C50:00 06CB:CDAA Touchpad"|grep Edges
#check the right edge dimension for the touchpad
synclient -l | grep RightEdge
#change the right edge boundary (and add this to startup programs)
synclient AreaRightEdge=900
#adjust cursor speed (and add this to startup programs)
xinput --set-prop "PNP0C50:00 06CB:CDAA Touchpad" "Device Accel Constant Deceleration" 1.05
#disable touchpad while typing (disable touchpad for 1 second after each keypress - add this to startup programs)
syndaemon -i 1 -t -K -R -d
