Ok after several thousand Google searches. credit to this post for having what i wanted
I finally found what i needed. the command to bring up the shutdown options in gnome.
I wanted to do what alot of other people have wanted to do is put a big arse shutdown button on the desktop for those computer users which can’t find the little one hidding in the right of your screen.
plenty of misleading post about a short cut to “sudo shutdown -h” but that’s not what I wanted.
Is the magical code you need to make it work.
how to make the shortcut that’s easy right click on the desktop “Create Launcher..” click.
Name: shutdown Command: gnome-session-save –kill Comment: anything you like.
And you can click on the icon and try and find a new one.
Then you are done a nice shutdown button for all your blind users.
