Binary package hint: gnome-themes

There is no Ubuntu theme with dark background in the theme package that is installed by default.

There are the special high contrast themes that do not look well on hardware that provides sufficient contrast, and there is the Darklooks modificattion of Clearlooks that is in the extra themes. Darklooks is usable and does have dark background but it looks somewhat bland since it has no colors.

Themes with dark background are useful because some screen defects manifest more noticeably when dark text is rendered on light background making the text harder to read. Also I find too light backgrounds tiring for my eyes.

Another reason to use dark background might be that it probably saves energy on most CRT screens ;-)
