CTRL-ALT-DEL in Ubuntu Platform

Hello guys, you definitely know what the function of CTRL-ALT-DEL keys in Windows environment. Yup, it is used to open task manager. Task manager allows us to see the running process, CPU usage, and other related stuff. Then, can we get a "task manager" in Ubuntu by pressing the same button combination. Yup, We Can.

We will use the CTRL-ALT-DEL in Ubuntu to open Gnome System Monitor. Gnome System Monitor is a tool that nearly equal to the task manager that runs in Windows environment.

Here are the steps.
First, make sure the Gnome System Monitor installed on your system. Open Terminal and type:
type: gnome-system-monitor

If the GSM has been installed you will see output like this:
gnome-system-monitor is hashed (/usr/bin/gnome-system-monitor)
If you do not see the output, then you need to install GSM, type
sudo apt-get install gnome-system-monitor -y
Second, open System –> Preferences –> Keyboard Shortcuts and press the Add button.
Fill in opened windows like the screenshoot below
Assign CTRL-ALT-DEL for Gnome System Monitor. If all the three keys has been used for other app, just disable it by pressing Backspace:
Select Gnome System Monitor, apply CTRL-ALT-DEL shortcut to GSM and press Close button
