Ah yes, I think I misunderstood (EE background so for me a LCD display is 
synonymous with panel) but you refer to the bars with start, task switcher 
etc. I actually found those at $HOME/.config/plasmashellrc and $HOME/.config/
plasma-org.kde.plasma.desktop-appletsrc

>From what I could deduce, it seems like the plasmashellrc file contains the 
panel description in size and a mapping of the screens, and the plasma-
org.kde.plasma.desktop-appletsrc contains the details of which widgets are in 
there. As it contains references to the actual widgets, their order, and it 
also seems to reference the screen. The lastScreen seems to coincide with the 
index under [ScreenConnectors] for the xrandr name of the screen.

This is all guesswork and reverse engineering based on observations, but I 
think this should help a bit. At least now I also know where to find these 
things when it borks up for me.

Note, as answer to your question, on one PC the configs directory is empty for 
me, and the other doesn't have it at all.
