There are lots of themes but are any of them ‘good’ and will they work on Plasma is a common question.
I suggest you google around and see what themes pop-up and see if you like them at all.
Then you can decide if you install them. There are different ways to install them
Installation via plasma-discover
We decided to give Helium a try and will install it together.
Press the button INSTALL.
This application will do exactly what we did manually in previous article (see link below). It will download, extract and put the contents where it needs to go in
and then it will come available in the system settings of Plasma.
You can follow our tutorials based on either of two iso's.
1. ArcoLinuxB Plasma (recommended)
We record the plasma video's on an SSD installed from the ArcoLinuxB Plasma iso.
You can either create your very own ArcoLinuxB Plasma iso following this tutorial or download it from Sourceforge. (ArcoLinuxB-plasma-18.11.2.iso of 4.3 GB - games included)
2. ArcoLinuxD Plasma
You can also use the ArcoLinuxD iso and then install Plasma with the help of the github scripts. This will not be an exact copy of the iso.
Learn about the Plasma desktop and enjoy it.
