Fontconfig - May 2010 - Cannot change DPI in ~/.fonts.conf for X applications?

Hi all,

sorry for what might be a noob question. Only recently I discovered
the wonders of changing the DPI (I have poor eyesight for my high
resolution monitor).
I tried to change the DPI setting to something more acceptable (100 is
the ideal), but I cannot seem to be able to do it on ~/.fonts.conf. I
have there the correct setting:

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
 	<match target="font" >
  		<edit mode="assign" name="dpi" >
   			<double>100</double>
  		</edit>
 	</match>
</fontconfig>

However no application seems to take it seriously. But if I edit
~/.Xresources and add:

Xft.dpi:	100

the 100 DPI setting is enforced. Am I doing something wrong in
.fonts.conf or is this normal?

Regards,
Pedro

Different distros and distro versions have different ideas whether DPI should
be forced, and to what, and how to go about it if they do. You''ve
provided
neither your distro, and its version, and you''re not entirely clear
what DPI
you want, and you''ve said nothing about what DPI you''re
experiencing. There''s
only random likelihood anyone can help you get what you want without more
information.

Sorry for that, it was late and I completely forgot!

I''m using Debian testing (Squeeze) and my DPI is set to 96. My ideal
DPI for this screen, resolution and my eyesight is 100.
I have used it before - used to change it in
gnome-appearance-properties. I got rid of GNOME and now I''m using
openbox, so I need to set it in another way.

The link you sent me is very helpful. On http://scanline.ca/dpi/ it
says that gnome-appearance-properties changed the Xft.dpi, so I guess
I can stick to that one.

Thank you for your help.

Regards,
Pedro
