My display would be powered up when I reboot. But I do turn it off
frequently when not using it. I wonder if that could have an effect.

Well, I did figure it out, but it wasn't so quick. I had to experiment
a lot and wade through a lot of cruft. The config file in question is
/etc/fonts/fonts.conf. The file is in a rather oblique xml format, but
I eventually figured out that adding this near the end of the file
solves my woes:
<!-- Turn off subpixel font antialiasing and turn on full hinting.
[nessus@xxxxxxx]
-->
<match target="font">
<edit name="rgba" mode="assign"><const>none</const></edit>
<edit name="hinting" mode="assign"><const>full</const></edit>
</match>
I ended up just turning off subpixel antialiasing altogether, since no
matter which choice I used, there were annoying color artifacts in some
cases. VRGB worked the best, but even that did not eliminate the
unsightly halos completely.
