Mint Linux is my favourite Distro. I have it dual booting on all my notebooks and desktop computers.
However my one very big annoyance with it, is that to shut down the Distro, it takes 3 mouse clicks, to do so. So MS Windows, mentality. Ridiculous and not an elegant operation!!
I finally got annoyed enough, that I went and Googled for a 1 click shutdown, solution.
Here it is! It works great! https://community.linuxmint.com/tutorial/view/1113
Note: For the line about changing the default icon, that is used for the shutdown, I used the icon suggested in one of the Comments. The icon is titled, gnome-shutdown.svg
However, on my Mint 18 install, this icon is not in the folder, shown in the Comment.
To change the default shutdown icon I right clicked on the default shutdown icon, that shows up on the desktop. Click on Properties, in the menu. Left click on the icon image, in the window.
Click on the icons folder, that shows on the left hand side of the window. Scroll down the list of icons, until you find the, gnome-shutdown.svg and click on it and the Open button, if necessary.
Now, I have an "elegant way", of shutting down my Mint Distro! :-)
