It is a fact (and it is only human) that we will search for a similar workflow and setting on this Plasma desktop as the desktops (Xfce, Openbox and i3) we are accustomed to. We must be aware they are NOT the same and we will need to adjust sometimes our workflow. But let us see it as a challenge to come as close as possible.
On Xfce or Openbox or i3 I will immediately deactivate the notification that I am connected to the network. I do not think about it. It is a reflex.
On Plasma you can do the same if you want. I am working on a desktop. My network is always up since it is connected with a LAN cable. I do not want to see this message at every boot up.
In the picture above and in the video you can see where the setting is to deactivate this particular notification.
Use your time to see that there are still many more events that can trigger a notification. You might find ones you want to activate or deactivate at once.
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.
