I've been trying to check out KDE 5.1 Plasma but so far the live CD images won't install in VMWare Player. I can play them but the included theme has no transparency as far as I can see(pun acknowledged.) Since I can't install I can't download themes and use them etc..
I tried going the Ubuntu 14.10 route and got one to install, but it gives video errors on startup. I have to boot to the default window manager, get the error, then switch to the Plasma. If I boot directly to the plasma I get black screen or scrambled eggs. Just not worth the effort.
Right now I don't have an expendable machine to try installing on the metal.
