Resetting the Graphical User Interface (GUI) in Linux using Shell-Bash

As a programmer, you may sometimes encounter issues with the graphical user interface (GUI) in Linux, such as freezing or crashing. In such scenarios, resetting the GUI can help resolve the issue. In this article, we will discuss how to reset the GUI in Linux using Shell-Bash.

Step-by-Step Guide

Follow these steps to reset the GUI in Linux using Shell-Bash:

1. Open the terminal on your Linux machine.

2. Press the 'Ctrl + Alt + F1' keys to switch to the command-line interface (CLI). This will take you to a non-GUI shell.

3. Type in your username and password to log in.

4. Enter the following command to stop the GUI:

   sudo service gdm3 stop
   

   This command will stop the GNOME Display Manager (GDM), which is responsible for managing the GUI. If you are using a different desktop environment, such as KDE, replace 'gdm3' with the appropriate service name for your environment.

5. Next, enter the following command to kill any remaining GUI processes:

   sudo pkill X
   

   This command will kill the X server, which is responsible for rendering the GUI.

6. Finally, enter the following command to restart the GUI:

   sudo service gdm3 start
   

   This command will restart the GDM service and start the GUI.

7. Press the 'Ctrl + Alt + F7' keys to switch back to the GUI interface. The GUI should now be reset and functioning properly.

Conclusion

Resetting the GUI in Linux using Shell-Bash can help resolve issues with freezing or crashing. By following the steps outlined above, you can easily reset the GUI and get back to work. Remember to replace 'gdm3' with the appropriate service name for your desktop environment, if necessary.
