Description of problem:
When I first started the gnome desktop, the fonts were much too large. To get a
reasonable a display I had to set the font size to something ridiculously small.
So I set the gconf value to 75, the only value that delivers good results for
all X apps.
Unfortunately I couldn't use gconf-editor, as it crashed on this particular option.

I think we had a fairly compelling rationale for the current default dpi 
(including that both mac and windows use it, but there were other reasons also), 
but gconf-editor should be fixed.

If your fonts were really wrong it may have been some non-dpi-related issue, I
don't know.

Comment 3 Gérard Milmeister 2002-10-10 14:46:56 EDT
Here is my configuration:
I have a 17" monitor and resolution 1280x1024. The ddc detects a resolution of x
times y dpi, where x and y are different and between 90 and 100 or so. This is
the right thing to do of course, e.g. to display real circles correctly in a
graphics program.
However, GNOME 1.4 apps and most other 'legacy' apps use the Helvetica 12pt
bitmap font for its menus (which I still find the best-looking font for
non-antialiased display). So it is really unsettling to see that if you select
for example Arial 12 pt in GNOME 2.0, its real size is very different from the
usual Helvetica 12pt font.
I had to set both the X server dpi setting and the gconf setting to 75, so that
I get the former, in my opinion, consistent setting.
I hope you understand that I see this as a problem?
So in short, I expect that Arial 12pt in GNOME 2.0 has the size that I have in
other apps.

We are working on making all font rendering on the system use fontconfig
and Xft, so that will make Helvetica 12 the same size in all programs.

The separation of physical DPI from the "logical" DPI used to convert
font points into pixels:

 a) Generally is the right thing to do - appropriate font sizes depend more
    on angular resolution than linear resolution - think of a handheld
    that you view the image from a foot away, or a projector where you view
    the image from 30 feet away.
 b) Is needed because using a fixed logical DPI is needed to get good
    looking user interfaces unless all elements (images, lines, etc)
    in the interface are scalable. 
 c) Is what windows does (as well as a default logical dpi of 96), so is 
    needed to correctly display web pages.
 d) Is needed because physical resolution is often autoprobed incorrectly
    by X.
Comment 5 Gérard Milmeister 2002-10-10 18:38:44 EDT
Well, as I said this is true, but currently the result seems to be less than
optimal, and from discussion forums I see, that I am not the only one
disatisfied with the resulting, actual font sizes.
