I lost the taskbar on my Raspberry Pi
but I can't figure out how to bring it back.
What can I do?
Just do an update, this is a known problem with the latest Raspbian Stretch image. When you enable the VNC server, this can happen. Alternatively, if you don't need the VNC server, you can disable it.
sudo apt-get update
sudo apt-get upgrade
Try moving/renaming/deleting ~/.config/lxpanel then logging out and back in perhaps?
Required, but never shown
