To get dual display working I selected preferences | display, cleared mirror screens then dragged my desired placement as expected. ... Nothing special at all.

I had hoped to find the time to post an "how to" on a vertical monitors only layout. With SUSE I did have this problem, never with Mint or Ubuntu. I can't find the time to put suse down again - would have to wipe Mint - for a step by step tutorial but it amounted to:-
Installing arandr - Just so useful for any dual display work, Gnome or KDE.
After a lot of messing around I figured out the display drivers weren't setting refresh rates correctly even though xrand said they were and this was eating the available memory. I created the appropriate modes including vertical and horizontal refresh rates and then everything worked.
