Not yet.... But I've just been googling the net & find a number of 
references toFn-F combinations not having worked in Ubuntu a couple of 
years ago, and also that Toshiba (apparently) is locked into M$ & cannot 
supply info for Linux.....

Found that if I use xrandr --output <a> --same-as <b> I can get both 
screens to have (basically) the same image - although not at the same 
size!  But then zoomed out, found the 2 images under each other (rather 
than side by side) & I lost my panel again - wish I knew where they went 
(probably the same Black Hole where odd socks end up!)

Maybe someone from KDE can tell us how to change kcmrandrrc so as to get 
at least the 2 screens showing the same image on startup! then we can 
use xrandr to switch the laptop screen on and off...
