Note that whether fonts are &quot;ugly&quot; is very subjective, and also varies
depending on one's eyes.

For example, people who wear glasses will often prefer their text *not*
to be antialiased, especially when the screen resolution is under 150
dpi and the viewing distance is under 18 inches / 0.5 metres) or so.

</I>For some fonts and for many (most?) people, this will look worse.

</I>
I can't even see size 8 on my laptop without a magnifying glass. Not
because of my vision, but because 8pt text gives letterforms that for
lower case x-height is typically 1.4mm -and 8px gives me 0.7mm high
letters.

You can turn off the bytecode interpreter, e.g. using gnome in
preferences/appearance under fonts/details, or in fonts.conf, but you
can't turn it back on if it was disabled at compilation time.

You can also turn off antialiasing and sub-pixel positioning.
