Fix Lost Dolphin File Copy Progress Notification
System: Kubuntu 18.04
Problem: No longer able to see file copy progress, e.g. Dolphin so you can’t monitor the progress and have no idea when it will complete
Solution edit the Plasma configuration file as follows:
Run Terminal and stop Plasma
kquitaap5 plasma
Edit
nano /home/[user]/.config/plasma-org.kde.plasma.desktop-appletsrc
Add the following
[AppletGlobals][plasma_applet_systemtray] ShowJobs=false ShowNotifications=false
Start Plasma again
kstart plasmashell
