Usually I keep terminal running and I use ” poweroff ” command to shutdown the machine. Adding additional power option to your user account menu in Gnome Shell user interface for easily shutdown “poweroff”, and hibernate from user menu.
Download Power options 2.0 extension Here.
Extract the file and paste the folder into this path
~/.local/share/gnome-shell/extensions/
Then restart gnome shell using ALT+F2 then type “r”.
That’s it for now.



One of necessary extensions. Thank you!
You are welcome.
