Some tips on making the default font config more palatable.
I have a respect for good bitmap fonts, like misc-fixed-medium-r. But when bitmap fonts aren't monospaced, they start to get painful very quickly.
You can disable bitmap fonts by doing:
# cd /etc/fonts/conf.d
# ln -s ../conf.avail/70-no-bitmaps.conf
For some reason, someone thinks that Nimbus Sans is a replacement for Helvetica. They are wrong, on many levels, especially as the on-screen kerning of Nimbus Sans is extremely wonky on Debian.
Grab a copy of 70-no-nimbus.conf and install it in /etc/conf.avail/.
# cd /etc/fonts/conf.d
# ln -s ../conf.avail/70-no-nimbus.conf
"Helvetica" now matches Bitstream Vera Sans - much better!
