truetype fonts in x11, wrong metrics?

Hi all,

I've recently switched from Sarge to Etch (I've decided to do a
reinstall, not an upgrade, because I also wanted to repartition the hard
disk) and in the last few days I've been restoring my customizations.

I've run into a problem with fonts. In Sarge I had configured Emacs to
use the same font as the Gnome Terminal, and I want to do the same thing
in Etch. The font family Gnome is using is "DejaVu" (package
ttf-dejavu). As this is a TrueType font, it isn't immediately available
from Emacs: it has to be registered first as an X11 font. I had been
able to do that in Sarge by following directions from this page:
http://www.paulandlesley.org/linux/xfree4_tt.html (specifically, section
4.2) and tried to do the same in Etch. Basically the procedure is:
1. go to the directory where the TrueType fonts are stored (that is
/usr/share/fonts/truetype/ttf-dejavu)
2. run ttmkfdir (creates fonts.scale)
3. run mkfontdir (creates fonts.dir)
4. in /etc/X11/xorg.conf add the following line to Section "Files":
FontPath /usr/share/fonts/truetype/ttf-dejavu
5. restart the X server
(of course must be done as root)

So this worked in Etch too: after the procedure, "xlsfonts | grep
dejavu" shows quite a lot of fonts. The one I want seems to be
"-misc-dejavu sans mono-medium-r-normal--15-150-75-75-m-0-iso10646-1"
(in the Gnome font panel it's listed as "Monospace, 12 pt"). But
strangely, when I run Emacs with this font, the text window isn't
dimensioned correctly: it should be 80 characters wide, but only 72 fit
within. There's also some extra spacing between lines. See attached
screenshot: the Gnome Terminal window shows what it should look like.

I guess that Emacs doesn't get the font metrics correctly. I don't know
which I should blame -- the font files, Emacs or X-Windows. Anyway, does
anyone know what I could do to fix this?

Please Cc: me, I'm not subscribed.

Thanks everybody
Gerardo
