I used the Cinnamon default that came with my install of Linux Mint 18.1. Love it and it works just fine. I am just returning back to the Linux world after losing faith with Ubuntu last few years. Friend told me about MINT and he was right. Great OS. Well I did want to experiment with the KDE desktop so I did a command line install, update, was brought to a screen asking to choose how I wanted to choose my desktop environment at boot. Figured I was all good. I rebooted and still I am given no option and it just starts up in my original Cinnamon.
