I've been very happy with Linux Mint 17, and the Cinnamon GUI.
Except for the occasional system freezes. This happened usually when I was swapping between windows (alt+tab), and required a re-login.
I've spent some time looking around the web and trying to diagnose the problem. I've found one change that seems to have cleared up the problem, and I am not aware that anyone else has mentioned it yet. I've uninstalled Firefox (31), and replaced it with Google Chrome. I haven't had a freeze since doing that. Fingers crossed.
