Introduction to Ubuntu’s Interface
Before we dive into the nitty-gritty of finding running applications, it’s essential to understand the basics of Ubuntu’s interface. The default desktop environment for Ubuntu is GNOME, which provides a user-friendly and intuitive interface. The GNOME interface consists of a top bar, a dock, and a desktop area where you can launch applications and access files. Understanding the layout and functionality of the interface will help you navigate through the system more efficiently.
Navigating the GNOME Interface
To navigate the GNOME interface, you can use the mouse or keyboard shortcuts. The top bar displays the current time, system indicators, and a menu to access system settings. The dock, located on the left side of the screen, provides quick access to frequently used applications. You can also use the Alt + Tab keyboard shortcut to switch between open windows and the Super + D shortcut to show the desktop.
Accessing the System Menu
The system menu, located on the top right corner of the screen, provides access to system settings, user accounts, and shutdown options. You can click on the system menu to access these options or use the Alt + F2 keyboard shortcut to open the run dialog box. The run dialog box allows you to execute commands and launch applications quickly.
Methods to See Running Applications
Now that we have covered the basics of Ubuntu’s interface, let’s explore the various methods to see which applications are running on your system. There are several ways to achieve this, including using the GNOME interface, command-line tools, and system monitoring applications.
