After making all these tutorials it sometimes happened that simplescreenrecorder was started at login. 

Plasma will standard remember the apps in your last session and will reload them when you log back in.

Where can we tell Plasma to start with a clean session aka no apps from a previous setting?

You can see the setting in the picture and in the video.

Plasma Challenge

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.
