KDE 5.15: Missing taskbar
Solution 1
At first, try restarting the Plasmashell.
In KRunner, run:
kquitapp5 plasmashell && kstart5 plasmashell
Could you please have more details? Distro? Video card? Open-source driver or proprietary driver?
Solution 2
If you haven't tweaked your taskbar much, you can add a new panel by simply right-clicking on your Desktop, and then Add Panel > Default Panel

I am having an issue with kde 5.9, task bar is not showing anymore. Desktop wallpaper is black. I can still open application with CTrl+F2. I tried few commands and get this:
Any idea on how to show task bar again ?
Thank in advanced
