If you are a beginner at Ubuntu Linux and you have changed operating system from Windows, the following guide is for you. We will see how you can set CTRL + ALT + DEL to open it Task Manager in the Ubuntu.
In Windows, pressing the three keys CTRL + ALT + DEL opens Task Manager (Task Manager), which provides you with information about running processes and services, among other things. By Task Manager, you can terminate the processes, if you need to, check the CPU usage of the memory, etc.
Στο Ubuntu Linux you can have a similar tool like Task Manager called gnome-system-monitor for the GNOME desktop. Other desktop environments have similar tools, which you can configure in a similar way.
By default, if you press CTRL + ALT + DEL, the Ubuntu displays the default setting for disconnection set for these keys.
You will need to change these default settings first.
From Show applications, search for settings. Open the settings and go to the keyboard settings.
Scroll down to the System section and click Log out.

Click on + and a window will open to select the application you want to run with the shortcut you add. Select KSysQuard from the applications on the System. Then click on the box I marked below and add the shortcut you want.
