Here is an example of how to make fontconfig capable of finding trad
fixed.  We need part of the attached file.

17:30 <Diziet> gitk seems to be using something that doesn't understand fixed.

17:33 <mdw> http://www.distorted.org.uk/~markw/t/gitk-fixed.png <- it's possible
17:33 <Diziet> Good.  How ?
17:34 <Diziet> set textfont fixed
17:34 <Diziet> ^ does not work
17:34 <mdw> http://git.distorted.org.uk/~mdw/profile/blob/HEAD:/dot/fonts.conf
            <- trick 1
17:34 <Diziet> jeez
17:35 <Diziet> Should that file be in xfonts-traditional ?
17:35 <mdw> set textfont {MiscFixed6x13 12} <- trick 2
17:35 <mdw> Not sure.
17:35 <mdw> Making use of the fake font once it's there can be... tricky.
17:36 <pm215> truly you are the wisdom of all fonts
17:36 <Diziet> I put that in /etc/fonts/conf.d/90-tradfixed.conf and now "set
               textfont fixed" works
17:36 <Diziet> And "Fixed" now appears in the list of fonts in the gui font
               selector.
17:37 <Diziet> Seems perfect to me.
17:38 <mdw> Really!?  Wow.  It always required hideous bodging for me. :-/
17:39 <Diziet> And I can select it in gnome-terminal.  (Which comes up in black
               on black by default ...)
17:39 <mdw> That's really strange.
17:39 <Diziet> Is it ? :-)
17:39 <Diziet> May I put your file in my package ?
17:40 <Diziet> Also may I paste this conversation into the bug report ?
17:40 <mdw> By all means.
17:40 <mdw> Ahh.  For me, plain `fixed' gives me misc, not trad.
17:41 <Diziet> Did you tell xfonts-traditional to fiddle the "fixed" alias ?
17:41 <mdw> I told it not to, I think.
17:41 <Diziet> Ah well there's your problem :-).
17:42 <Diziet> Anyway including your fontconfig guff is clearly a step in the
               right direction.
17:43 <mdw> Oh.  I tell a lie.
17:43 <mdw> Template: xfonts-traditional/remap-fixed
17:43 <mdw> Value: true
17:43 <Diziet> Looking at your fonts.conf stanza there it seems like it ought
               to DTRT
17:43 <mdw> And `xterm -fn fixed' is right.  OK, now I'm officially confused.
17:46 <Diziet> Looking at that file, I think xfonts-traditional wants only part
               of it.
17:46 <mdw> That's quite likely.
