In this issue, the editor will bring you about how the Linux system uses the on-screen keyboard. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

Sometimes the on-screen keyboard is very important, for example, when your physical keyboard is broken, or you don't have enough keyboards, and you have to apply the on-screen keyboard, how to use the on-screen keyboard in the Linux system?

Fortunately for installing Florence on-screen keyboards in Linux, Florence exists in the base repository of most Linux distributions.

In Debian,Ubuntu or Linux Mint:

Sudo apt-get install florence is in Fedora,CentOS or RHEL (CentOS/RHEL requires EPEL repository):

$sudo yum install florence is in Mandriva or Mageia:

$sudo urpmi florence for Archlinux users, Florence exists in AUR.

Configure and load the on-screen keyboard when you have installed Florence, you can simply type the following command to load the on-screen keyboard:

Florence by default, the on-screen keyboard is always on top of other windows, allowing you to type on any active window.

Click the tool button on the left side of the keyboard to change the default configuration of Florence.

In Florence's "style" menu, you can customize the keyboard style to enable / disable sound effects.

In the window menu, you can adjust the keyboard background transparency, key opacity, and control the keyboard scale, toolbar, size, and always top features. If your desktop resolution is not very high, transparency adjustment is very useful because the on-screen keyboard will block other windows. In this example, I switched to a transparent keyboard and set the opacity to 50%.

In the behaviour menu, you can change the input method. Florence supports several different input methods: mouse (mouse), touchscreen (touch screen), timer (timer), and walk (ramble). Mouse input is the default input method. The last two input methods do not need to press the mouse button. The timer input triggers the key by holding the pointer on the key for a certain period of time. The principle of walking input is similar to that of timer input, but after training and dexterity, it can be faster than timer input.

In the layout menu, you can change the keyboard layout. For example, you can expand the keyboard layout to add navigation keys, number keys, and function keys.

Using only the mouse to manipulate the Ubuntu desktop I will demonstrate how to integrate Florence into the Ubuntu desktop, and then we can get to the desktop without a physical keyboard. This tutorial uses LightDM (the default display manager for Ubuntu) to enter Ubuntu, and other desktop environments can set up similar environments.

A physical keyboard is required for initial setup, but once set up, you only need a mouse, not a keyboard.

When you start the Ubuntu desktop, the launcher ends up in the welcome screen of the display manager (or login manager). You need to enter your login information on this interface. By default, the Ubuntu desktop uses the LightDM display Manager and the Unity welcome interface. If you don't have a physical keyboard, you can't enter a user name and password in the login interface.

In order to be able to load the on-screen keyboard in the login interface, install the GTK+ welcome interface with on-screen keyboard support.

Sudo apt-get install lightdm-gtk-greeter then opens the welcome interface configuration file (/ etc/lightdm/lightdm-gtk-greeter.conf) with an editor and specifies Florence as the on-screen keyboard to use. If you prefer, you can also use Ubuntu's default on-screen keyboard onboard instead of Florence.

$sudo vi / etc/lightdm/lightdm-gtk-greeter.conf [greeter] keyboard=florence-no-gnome-focus &

Restart the Ubuntu desktop and see if you can use the on-screen keyboard in the login screen.

When you see the GTK+ Welcome screen after launch, click on the humanoid symbol in the upper right corner. You will see the "use on-screen keyboard (On Screen Keyboard)" menu option, as follows:

Click this option and the on-screen keyboard will pop up in the login screen. Now you should be able to log in with the on-screen keyboard.

The official Florence web page provides documentation (documentation) on how GDM2/GDM3 users use the on-screen keyboard on the GDM2/GDM3 interface.

The last step in completely keyless Ubuntu desktops is to let the on-screen keyboard start automatically after login so that we can manipulate the desktop without using the physical keyboard after login. To do this, create the following desktop files:

$mkdir-p ~ / .config/autostart$ vi ~ / .config/autostart/florence.desktop [Desktop Entry] Type=ApplicationName=Virtual KeyboardComment=Auto-start virtual keyboardExec=florence-- no-gnome allows you to see the on-screen keyboard when you log in to the desktop.

This is how the Linux system shared by the editor uses the on-screen keyboard. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
