How to hibernate from the lock screen on Ubuntu 18

By default Ubuntu doesnt support hibernate option. Even when u enable it using "pm-utils" during resume(wake-up) your laptop will not require password. 
And this is very risky moment. 

In my case, I created a keyboard shortcut which enables hibernate and lock. 
Today I will share steps how you also can do it for your laptop/pc.



1. Check and install "pm-utils" and ''uswsusp"

$ sudo apt install pn-utils
$ sudo apt install uswsusp

2. Allow user to execute hibernate without password:

$ sudo visudo
...
#includedir /etc/sudoers.d
youruser ALL=(ALL) NOPASSWD:/usr/sbin/pm-hibernate

3. Open Keyboard settings and add shortcut as below:

Shortcut: Ctrl+Alt+H
Comand: gnome-terminal -e 'bash -c "gnome-screensaver-command -l; sudo pm-hibernate;"'

That is all. Now you can hibernate your computer with lock screen using command Ctrl+Alt+H
