I can't figure out where fvwm is getting the xpm icon for an xterm. The issue started when I upgraded from Debian v7 (fvwm 1:2.5.30) to Debian v9 (fvwm 1:2.6.7-3). In both cases fvwm-icons was also installed.
I have this in ~/.fvwm/config: Style "XTerm" Icon null.xpm, SloppyFocus, IconBox 200x200-1+8 where null.xpm is intended to call /usr/share/pixmaps/fvwm/null.xpm, a zero-byte file I created. When startx is called, it gets this from ~/.xinitrc: xterm -geometry 125x58+964+56 -iconic -title syrano -e ssh syrano & No matter what I list in config, the xterm icon that comes up matches /usr/share/pixmaps/mini.xterm_48x48.xpm (an icon with a blue `T' over a red `X'). If I copy some other xpm on top of that and do startx again, I still get the original mini.xterm_48x48.xpm image. Furthermore, /usr/share/pixmaps/mini.xterm_48x48.xpm still shows an access time from weeks ago. It seems that fvwm has that image cached or built in somehow. Once fvwm is up, if I call "xterm &" and convert that to an icon, it appears as a live window screenshot, not as mini.xterm_48x48.xpm. In Debian 7, calling null.xpm gives me no xpm icon, just a title bar labeled "syrano". I prefer this because it's very small. Thanks.
