This is very useful stuff. I didn't know about the DisplaySize setting
- that sounds much better than specifying -dpi on the X server command
line.

Actually, the Xft.dpi setting is more of a workaround for a faulty X
setting; it shouldn't be necessary at all if the X server is set up
properly as you did. Hmm, I wonder how to tell gnome-settings-daemon
not to mess with it..

Wow, cool.

Yes, I agree it would be nice. But that belongs in the X department,
not with us.
However, I do think we should try and put all this down in the
README.Debian, because I'm sure that being able to display documents at
100% as true physical size is something that many people would like to
do.
