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
