Installing KDE Plasma 5 on CentOS 8

You can watch the following video. There are also text instructions below the video. (including getting sddm working)

I started off with just a boot install of CentOS 8, so I wouldn’t have Gnome or any other unnecessary cruft installed. After installation, I enabled the EPEL repository – latest directions for that are here.

After that, I had to install KDE by typing:

sudo dnf groupinstall “KDE Plasma Workspaces”

systemctl set-default

Then startx started Plasma.

I didn’t spend time getting the display manager working, but it’s pretty easy. After having done all of the above (but before you use startx), type:

systemctl enable sddm

A reboot later you’ll have your graphical login.
