1. System update

We use the shortcut key Ctrl + Alt + T to open the terminal and enter the following command to complete the system update.

sudo apt update
sudo apt upgrade

2. The pointer on the touchpad moves slowly, how to adjust it?

We use the shortcut key Win + I to open the center, and find the touchpad function in devices.

Click the pointer speed status bar in the right panel, and we can keep trying the moving speed until the speed is adjusted to suit our habits.
