Thanks. That could to explain how it comes up with the mini.xterm_48x48.xpm
image in /usr/share/pixmaps even when I overwrite it with something else.
As a test, I put this line into ~/.fvwm/config:
Style xterm Icon /usr/share/pixmaps/gimp.xpm
I also had these in ~/.xinitrc:
xterm -geometry 125x58+964+56 -iconic -title syrano -e ssh syrano &
xterm -geometry 125x58+964+56 -iconic -title numbat -e ssh numbat &
Then I went through many cycles of exiting fvwm and calling startx. The
icons for the two xterms varied a lot from one trial to the next but were
always either the mini.xterm_48x48.xpm image, a live screenshot, or the
intended gimp.xpm. At some point I noticed that whichever xterm icon came up
first usually got gimp.xpm, while the second xterm got one of the other two
images. This seemed to be time-dependent, in other words. When I added
"sleep 1" between the two xterm calls in .xinitrc, I consistently got
gimp.xpm for both icons, as well as for any xterms I called from the command
line and iconized.
For reasons I can't guess, this did not work with another standard xpm
(inkspace.xpm). It did work with smplayer.xpm. It did not work with my
0-byte null.xpm or a 1-pixel red xpm that I created. The icons display in
reproducible positions on the desktop, but they are not the same positions I
saw before switching to gimp.xpm. I have a little more work to do.
Thanks again.

As you seem to be having trouble, here's a fuller answer than the one
I posted before.

Then you need to have
Style xterm Icon fvwm/null.xpm
or it won't be found in that subdirectory.
That said, I would put the Icon in a directory like
/usr/local/share/fvwm/ or /home/david/.fvwm/null.xpm rather than
polluting the package's own files.
Again, that said, a zero-length file doesn't work for me on stretch.
I haven't tried jessie or wheezy.

That does seem likely. If you look at the man page, it explains the
old option -n and says "If no suitable icon is found, xterm provides a
compiled-in pixmap" which would correspond to your reported behaviour
as it can't find /usr/share/pixmaps/fvwm/null.xpm.

That's because at this point I assume you hadn't added
Style xterm IconOverride
to prevent it. As I wrote before, iconification is quite complex,
even before you add in fvwm's options.

If you just want a small icon, why not just shrink it; say:
$ convert /usr/share/pixmaps/…whatever….xpm -resize 48x24 .fvwm/small.xpm
Even a 1x1 icon makes a (not very useful) mark on the screen (until you
hover over it).
Cheers,
David.
