Konqueror has its own font settings which should default to KDE-wide settings 
for some fonts and have some builtin defaults for others. They can be changed 
independently in Konqueror''s settings.

recent fontconfig versions have fixed a bug.

Please give fontconfig 2.1.94 a try and see if you still have problems of 
this nature.  If so, please include your .fonts.conf file (and local.conf 
file if any) so that any missteps in the configuration file can be sorted 
out.

Here''s what I added to my ~/.fonts.conf file to select the fonts you 
mentioned:

	<alias>
	        <family>serif</family>
	        <prefer>
	                <family>Nimbus Roman No9 L</family>
	        </prefer>
	</alias>
	
	<alias>
	        <family>sans-serif</family>
	        <prefer>
	                <family>Luxi Sans</family>
	        </prefer>
	</alias>
	
	<alias>
	        <family>monospace</family>
	        <prefer>
	                <family>Luxi Mono</family>
	        </prefer>
	</alias>

One additional question is what your LANG or LC_ALL environment variables 
are set to -- fontconfig uses the local language to help direct font 
selection to fonts that can support that language.  Explicitly using the 
family name overrides that part of the match.

Hello everybody,

This message is being sent to fontconfig@fontconfig.org and 
freetype@freetype.org. I hope I''m not doing something heretic.
I''m not very
familiar with mailing lists.

I wrote a simple html file to compare the font selected when specifying a 
general family name versus the result when specifying my prefered font for 
the same family. For example, I expect the the following strings to render 
identically:

  <font face=''serif'' size=''+3''>SERIF :
Default</font>
  <p>
  <font face=''Nimbus Roman No9 L''
size=''+3''>SERIF : Nimbus Roman No9
L</font>

I have found cases in Mozilla 1.3 and Konqueror 3.1-12 where this simple 
assumption isn''t met.

My prefered fonts for each family are:
Nimbus Roman No9 L
Luxi Sans
Luxi Mono

- In Konqueror, a string rendered with ''sans'' uses
''Comic Sans MS'' rather
than ''Luxi Sans''.

- In Konqueror, a string rendered with ''mono'' uses
''Andale Mono'' rather than
''Luxi Mono''. ''Andale Mono'' is my 3rd
prefered font in the monotype family.

- In Konqueror, the aliasing is different for strings rendered with the same 
font but obtained differently. For example, the initial S in my short html 
example above receives different aliasing. xmag confirmed my eyes
didn''t
play a trick on me.

- In Mozilla, a string rendered with ''monospace'' has a
different size than
the same string rendered with ''Luxi Mono''. ''Luxi
Mono'' and ''mono'' yield the
same result.

- A quick test on aliasing in Mozilla doesn''t reveal any difference.

I removed the msttcorefonts package and reloaded xfs and still obtained 
strange results.

- In Konqueror, a string rendered with ''serif'' used my
''sans-serif'' font.

- In Konqueror, the aliasing now seems to be the same.

- In Mozilla, the result stayed the same.

Software I''m using:
- Base distribution is a fresh RedHat9 install
- I first saw the problem with FreeType 2.1.3-6 (RH9 default). Then I 
upgraded to 2.1.4 and still had the same results (restarted X and xfs in the 
move).
- corefonts.sourceforge.net package
- Default RH9 OpenOffice, from which I am using ''Andale Mono''
as the 3rd
prefered font in the monotype family
- Mozilla 1.3 I installed to replace Mozilla 1.2.1 shipped with RedHat9.
- Default XFree in RedHat9: 4.3.0-2

Here''s the html I used for this little test:

<html>
  <head>
    <title></title>
    <meta content="">
    <style></style>
  </head>
  <body>

  <font face=''serif'' size=''+3''>SERIF :
Default</font>
  <p>
  <font face=''Nimbus Roman No9 L''
size=''+3''>SERIF : Nimbus Roman No9
L</font>
  <p>
  <font face=''sans-serif''
size=''+3''>SANS-SERIF : Default</font>
  <p>
  <font face=''Luxi Sans''
size=''+3''>SANS-SERIF : Luxi Sans</font>
  <p>
  <font face=''sans'' size=''+3''>SANS :
Default</font>
  <p>
  <font face=''Luxi Sans''
size=''+3''>SANS : Luxi Sans</font>
  <p>
  <font face=''mono'' size=''+3''>MONO :
Default</font>
  <p>
  <font face=''Luxi Mono''
size=''+3''>MONO : Luxi Mono</font>
  <p>
  <font face=''monospace''
size=''+3''>MONOSPACE : Default</font>
  <p>
  <font face=''Luxi Mono''
size=''+3''>MONOSPACE : Luxi Mono</font>
