The Maemo Extras -repository (and extras-devel / testing) contains community software for the N900 and the older Maemo devices. One of the nice packages available is the open “Droid Sans” -font set, originating from the Android project by Google. Droid Sans Mono works great with the Terminal application:
You can also hack the system theme to use Droid Sans with a simple perl one-liner.. you need the “droid fonts” and “rootsh” packages from extras repository installed first of course..
DISCLAIMER: Do this at your own risk, I might have made a mistake in this example…
$ root # perl -pi -e "s/Nokia Sans/Droid Sans/g" /usr/share/themes/alpha/gtk-2.0/gtkrc /usr/share/themes/alpha/gtk-2.0/gtkrc.input_method /usr/share/themes/alpha/matchbo*/theme.xml
Then switch theme to another and back, or reboot the device. Substitute “alpha” with “beta” for the orangeish theme variant if you like. Example below:
Switching back to Nokia Sans is left as an excercise for the reader
