I was using Unity on Ubuntu 14.04 and was giving me trouble after going dual monitors, so decided to give KDE a try. So I installed KDE by following the commands below found here hoping that I'll get Plasma 5.
sudo apt-add-repository ppa:kubuntu-ppa/backports sudo apt-get update sudo apt-get install plasma-desktop
I really like KDE but I have ended up with KDE Plasma 4.x as the --version says below:
$ plasma-desktop -version Qt: 4.8.6 KDE Development Platform: 4.14.2 Plasma Desktop Shell: 4.11.11
How do I get Plasma 5.4 (NOT 5.3 as it's unstable from what I read)?
