Underscore.

On single display systems and initial start, really? Most non-ancient systems 
do not have any /etc/X11/xorg.con*. Those that do are usually doing so for a 
reason.

This thread was intended to focus on single display configurations.

WRT Xorg automagic, I agree with the strategy. WRT global overrides that 
/etc/X11/xorg.con* contain, I don't agree. It seems to me it should only be 
applied via a KScreen non-default user config option to disregard 
/etc/X11/xorg.con* either entirely, or maybe though a submenu of specific 
categories.

What about users relying on proprietary NVidia drivers, which seem dependent 
on /etc/X11/xorg.con*? (I'm not among them. Maybe KScreen is a replacement 
for that dependence?)

Sounds like it. A new option in kdmrc? Something special in ~/.config/ or 
~/.kde/?

This too sounds good, for appropriate definition of "first boot".
