How does one set the configuration of multiple screens in Leap?. The
"Display and Monitor" button no longer displays the options to select
screens, sync etc.

I found that if I look at the Display settings center under the KDE
window, the correct display appears. What changed under LEAP so that the
display configuration window that used to appear correctly under FVWM
now fails? And how can I fix it?

KDE's display configurator relies on xrandr, so absent the KDE settings window,
you can nevertheless use xrandr yourself. Screen configuration can also be done
using xorg.conf*, which has always been my preference.

For setup via xrandr, has many examples,
among which many are for dual displays. Each line uncommented can stand alone.
IOW, it only takes one line to get the job done. Dual display lines include one
of strings "above", "below", "right-of" or "left-of". Subject to limitations of
one could put a one-line script in /etc/X11/xinit/xinitrc.d/ (or in ~/.xinitrc;
not personally tested).

For setup via xorg.conf, files in can serve as
templates to build your own.

If you had ever told us the configuration you want and provided hardware specs,
I would have made you custom files. These two have been specifically tested to
work for KF5 on openSUSE with NVidia GeForce 8600GT and nouveau driver:

xrandr method:
xrandr --dpi 120 --output DVI-I-1 --mode 1280x1024 --output DVI-I-2 --mode
1920x1080 --right-of DVI-I-1

xorg.conf* method:

The xrandr method, placing the command in /etc/X11/xinit/xinitrc.d/setup, does
NOT work using startx to run an XFCE session on 42.1. You may encounter the
same limitation using FVWM (as discussed in above bug 929016).

I suggest you try the xorg.conf* method file as /etc/X11/xorg.conf after
modifying its specified modes to match your displays, and DisplaySize to
match your taste (or delete the whole line to use 96 DPI).
