Yes, but failed to notice that long complex command
I saw -s <size> and thought I'd found the right switch.

I guess you mean this monstrosity?
Have one small 1280x800 LVDS screen showing a small version of a huge
3200x2000 desktop, and have a big VGA screen display the surrounding of
the mouse at normal size.
xrandr --fb 3200x2000 --output LVDS --scale 2.5x2.5 --output VGA
--pos 0x0 --panning 3200x2000+0+0/3200x2000+0+0/64/64/64/64
Thanks... I'll try that
