Well I downloaded KDE on a spare drive and had a good go on it all day in fact, what did I think of it. Firstly it downloaded faultlessly and was easy to install. I found the boot up was quick and the picture quality was excellent far better than Cinnamon in fact more like a 3D screen and if it worked in Cinnamon it would have been the best experience that I could have had. But I found it confusing and difficult to navigate, so after trying to use it for a day I gave up and reverted back to...
Linux Mint 18 KDE
