gnome-terminal fonts will be extremely small in fluxbox.

gnome-settings-daemon --oaf-activate-iid=OAFIID:GNOME_SettingsDaemon --oaf-ior-fd=13

However, I found that the moment I launch gnome-font-properties, it changes to normal. What puzzles me is that how it works, because the gnome-font-properties is started somewhere else, either from menu, or commmand line.

env | sort > env.0
gnome-font-properties
env | sort > env.1
comm -3 env.0 env.1

— no difference

NB, gnome-font-properties also changes the window background as a side effect. Ahh…

ps -eaf | cut -c1-29,48- | sort > ps.0
gnome-font-properties
ps -eaf | cut -c1-29,48- | sort > ps.1

$ comm -3 ps.0 ps.1
        root     10245 10037 12 12:36 gnome-terminal

Aha, the gnome-settings-daemon!
