Sometimes Gnome desktop in Solaris OS shows some fonts not properly,
particularly font in xterm(1) not looks corresponding to its definition in ~/.Xdefaults

XTerm*font: -dt-interface user-medium-r-normal-m*-*-*-*-*-*-*-*-*

Actually, adding of

xset fp rehash

as a startup program to the session using gnome-session-properties(1) helps.
