Option 1: Install GNOME System Monitor with the Software Center

  1. Open up the Software Center from the Applications menu
  2. Search for GNOME System Monitor
  3. Select GNOME System Monitor from the results and click install.
  4. You can now launch the GNOME System Monitor. It will look something like this:

  1. Open the Terminal with Ctrl + T
  2. Run this command:

    sudo apt install gnome-system-monitor
  3. Follow the onscreen instructions.


Maybe this link will help you.

The terminal is capable of showing you running processes via the top command. All you need to do is open a terminal, whether on your desktop or, if things have frozen by pressing CTRL+ALT+F1 - F12, logging in and entering the top command.

  • drum, It's generally best to list the technique, steps, or commands needed, and then reference the source, rather than just posting a link, since links die. @Jay Thank you for the edit.
