As stated above, is there a command to open system monitor?

    Why don't you lock the System Monitor in Unity Launcher. That will be easy.

GNOME System Monitor

Run the system monitor from Terminal by typing: gnome-system-monitor

Alternatively, run this command by pressing ALT+F2 (or Super, also known as "Windows key") and typing gnome-system-monitor

Keyboard shortcut

You can add a custom keyboard command using the following steps:

  1. Go to System Settings
  2. Click Keyboard
  3. Open the Shortcuts tab
  4. Click the "+" symbol near the bottom of the window
  5. Give your command a title. E.g. System Monitor
  6. In the Command field, enter gnome-system-monitor
  7. Click Apply
  8. Click Disabled on your newly created shortcut
  9. Enter the key combination you want for your shortcut. E.g. Ctrl+Alt+M

Note: on Ubuntu 14.10, Ctrl+Alt+Del is already in use, but can be overridden.

    For those looking to mimic Windows, bind System Monitor to Ctrl + Shift + Esc, which is the shortcut to open Task Manager directly. Commented Aug 31, 2018 at 0:21

    FTR: in Gnome 40.3 instead of a + there's a list of shortcuts groups, and one of them says something like "additional shortcuts" (depending on localization), it serves as a placeholder for user shortcuts, so you can add a custom one in it.

Why open the terminal at all? You are opening an extra application, which you may not be able to close without closing the System Monitor, to open something that can be done with some keystrokes: Alt + F2 then type gnome-system-monitor. That's the most hassle free.


You can create a Keyboard Shortcut to easily open System Monitor.

Type Keyboard in Unity Dash, this will open Keyboard Settings. Click on Shortcuts, select Custom Shortcuts, click on add button. This will open a window.

Type any Name System Monitor and Command gnome-system-monitor, apply.

Now click on disabled and choose any Keyboard shortcut like Alt+E. This will easily open System Monitor when you press Alt+E.


To open the terminal press below key :


Then type this command on terminal:

$ gnome-system-monitor

Right click on process and click on Kill process.


In Ubuntu 18.04

  • Uninstall system monitor:

sudo snap remove gnome-system-monitor

  • Install system monitor with apt:

sudo apt install gnome-system-monitor
