It works just fine in fvwm. I ran this script in an xterm:
while /bin/true
do
printf '%s ' "$(date +%H:%M:%S)" >> /tmp/mousey-pos
xdotool getmouselocation >> /tmp/mousey-pos
sleep 1
done
I ran this command in another xterm:
$ tail -f /tmp/mousey-pos
I then moved the mouse around the corners of the screen, and then
the corners of the xterm window on the screen. I shifted to another
viewport¹ and repeated (screen, then xterm). Then I switched back
to the original viewport to interrupt the script. The mousey-pos
output is attached.
The coordinates are always for the screen that you are staring at,
not the entire virtual desktop. When you move viewports, the window
numbers naturally all change (except for the clocks/pager/xconsole),
but the X/Y values don't.
There's no need to keep any xterm in view while it's running, if
you're recording the output in a file.
If it really doesn't work for you, there may be some dependency on
the way you start fvwm in .xsession which affects the parent-child
relationships, but that's just a guess.
I also tested using it from a bound keystroke, borrowing the
contortionist's keystroke for re-execing my xinput configuration,
Shift-Ctrl-Alt-/, thus:
#Key slash A CMS Exec exec xinput-xsession quiet
Key slash A CMS Exec exec xdotool getmouselocation
$ tail -f .xsession-fvwm-0-log
confirmed that this works too:

I must bind it to a better key. It's a much more controllable
output than xev, John, but I can see virtues in both.
¹ viewport: I have a desktop that's five times wider and four times
higher than the screen, and I switch between these twenty viewports
with clicks in the pager window, or with WindowsKey-arrows or with
Ctrl-Alt-arrows.
A few of the window numbers: root is 1707, …561 and …409 are
swissclocks for two timezones, …761 is the pager, …750 the xconsole,
and all of these are the same in every viewport. …248 is where I ran
the program, started and finished (obviously), and drew the (2nd)
outline round. …400 is an identical xterm on the viewport "next door"
for the 4th outline to go round.
Cheers,
David.
