I recently updated my Kubuntu through the software centre and a whole host of items were updated. I had an issue where the screen would go blank/black after logging in. The CTRL+ALT+F1/7 did nothing
Then it rebooted fine after several restarts and I ran a few commands to update again through the cli.
sudo apt update
sudo apt-get install --reinstall sddm
sudo apt-get install --reinstall plasma-desktop
All went well and I restarted the machine. All works fine now except that my taskbar disappears completely and reappears a few seconds later. It does this every few minutes.
I checked panel settings and auto hide is off. Does anyone know what could possibly be doing this ? Please note I am quite new to the whole Linux thing, previously coming from OSX.
Versioning info is as follows:
$ plasmashell --version
plasma-shell 5.10.95
$ kf5-config --version
Qt: 5.9.1
