我在 dynabook GX83 上安装了 Ubuntu 20.04。我的触摸板完全不工作，但 USB 鼠标工作正常。虽然我想使用触摸板。我搜索并尝试了很多命令，但无法解决这个问题。
我尝试过的方法及结果如下。

我也尝试了下面这些命令但是触摸板不起作用。
sudo apt-fast -y install xserver-xorg-input-synaptics
gsettings reset-recursively org.gnome.desktop.peripherals.touchpad
gsettings reset-recursively org.gnome.settings-daemon.peripherals.touchpad
那么我应该怎样使用触摸板呢？
感谢您阅读这个长问题。如果您有任何想法，我将不胜感激。
答案1
我可以按照以下步骤启用 ubuntu 触摸板。
sudo nano /etc/default/grub
您将会看到如下一行
GRUB_CMDLINE_LINUX_DEFAULT='quiet splash'
并在此处进行如下编辑。
GRUB_CMDLINE_LINUX_DEFAULT='quiet splash psmouse.synaptics_intertouch=1'
最后运行这些命令即可生效。
sudo update-grub
sudo reboot
