Comment 167 for bug 67226

Yesterday I updgraded my work PC to Ubuntu 9.10.
I suffered the same problem.

I noticed that in /etc/fonts/conf.d there were the following links:

10-antialias.conf
10-hinting.conf
10-hinting-full.conf
10-hinting-slight.conf
11-lcd-filter-lcddefault.conf

Removing 10-hinting-slight.conf and adding 10-sub-pixel-rgb.conf worked for me.
