956 of those are misc fonts. However, the last time I tried xlsfonts
years ago, I am pretty sure there was much more than 1600 fonts there.
Also, there is nothing in the output from xlsfonts related to
Helvetica;
irwin@raven> xlsfonts |grep -i hel |wc -l

Can you confirm that on your testing system as well or is there some
additional package I should install to resolve this issue?
- Make sure you have xfonts-{100,75}dpi installed. Make sure you have the
X Server restarted since installing those packages.
- what output does "xset q" produce?
- how many and which files does ls /usr/share/fonts/X11/*/helvR14* find?
- Your X log (/usr/log/Xorg.*.log) and the
/usr/share/fonts/X11/*/fonts.dir files would also be interesting.

Hi Bernhard:
I now have a way to suppress the warnings, but I suspect those warnings
are incorrect in the first place.
To recap, in my original message I said
<quote>
Google searches for these types of warning messages turned up rather
old advice to install xfonts-100dpi and gsfonts-x11. I have
done that, but the warning messages persist.
</quote>
(Probably that old advice was yours. :-) )
But what I forgot to do was to restart X (which I thought of for
myself just before I received your e-mail suggesting it). When I did
that 268 Helvetica fonts were listed by xlsfonts and gv no longer
emits the warning messages.
However, there is an interesting question still remaining which is why
didn't I see these warning messages when I used gv before? From my
bash history, I had a big burst of gv activity ~3 weeks ago, and I am
sure I would have noticed these warning messages then.
I have complete logs of what is installed on my system, and
xfonts-100dpi has never been installed until now. And only
one version of gv has been installed during the life of this
OS (I originally installed Debian testing on this system last August).
Perhaps some library that gv depends on has been updated recently
to generate these (incorrect, I believe, see below) warning
messages?
The other puzzling thing is I actually have two side by side systems.
One has xfonts-100dpi installed with X restarted (which fixed the
warning messages that appeared on that system before) and the other
one (an X terminal with Debian testing core system + X server
installed and accessing the first system using X -query) does not so
that system is still emitting the warning messages. However, the text
results from gv look identical in the two cases. Of course, visual
inspection has its pitfalls, but in this case the comparison is helped
because the two systems have identical high-quality monitors. So from
this visual evidence I suspect gv is using fonts from
gsfonts/gsfonts-x11 to render Helvetica and emitting (or one of its
dependent libraries is emitting) an unnecessary warning about lack of
bitmapped Helvetica fonts from xfonts-100dpi | xfonts-75dpi that are
not actually being used for the display. If that is the case, that
is obviously an issue that should be corrected.
Of course, font issues always seem to be complicated, but if you have
some further suggestions of ways to test my two different systems
(one using X clients locally, one using them remotely via X -query,
but both of which show the issue if xfonts-100dpi is not installed) to
further clarify what is going on, I would be happy to perform such
tests.
Alan
