But.. I have run up Kubuntu 15.10 with Plasma 5 in a VM - just barely on my tiny atom machine - and, it's OK, but I'm not wild about it. It's all 2D and tablet/Windows 2 like. Libreoffice does not look nice in the new system. Of course, I haven't played around with customization yet.
Given KDE frameworks is separate from Plasma itself and Kdenlive - which is my only real reason for an eye on Plasma 5 - would work in, say, XFCE with the frameworks… would it be possible to backport QT frameworks 5 into Mint 17.0? Then I wouldn't have to upgrade anything else.
I doubt it for various reasons I can think of but I'm just askin'!

Thanks for info in advance.
