+Older programs such as @command{xterm} do not use Fontconfig and instead
+rely on server-side font rendering.  Such programs require to specify a
+full name of a font using XLFD (X Logical Font Description), like this:

+@example
+-*-dejavu sans-medium-r-normal-*-*-100-*-*-*-*-*-1
+@end example
+
+To be able to use such full names for the TrueType fonts installed in
+your Guix profile, you need to extend the font path of the X server:
+
+@example
+xset +fp ~/.guix-profile/share/fonts/truetype
+@end example
+
+After that, you can run @code{xlsfonts} (from @code{xlsfonts} package)
+to make sure your TrueType fonts are listed there.
