I've been fighting with F24 (gosh I  miss the good old days) but today it's
totally disconnected on me.

My laptop has developed an intermittent  backlight problem so i have it
driving my TV instead. While trying to resolve resolution issues between
and driving both the onboard LCD and the TV my KDE task bar has gone away.

Logging out and in doesn't restore it, and neither does a reboot. I also
tried starting Gnome,  which does, but the Wi-fi doesn't start.

Can annyone suggest what to try next?

You can right-click the desktop in KDE Plasma and add another taskbar.

​That was about the 2nd thing I tried (without success).
