Sounds like the "FontPath" settings in your XF86Config file do not match the "catalogue" settings in your xfs config (<X11etcdir>/fs/config). xfs is simply a decent cache, which can provide fonts over the network(only need to install on one machine, etc etc). Update your server config to use more font paths. You can augment the list at run time with "xset fp+ /path/to/more/fonts" if you don't want to touch XF86Config.
One thing is to make sure that you run "xset fp rehash" after adding new fonts and running "mkfontdir", since X doesn't automatically see new fonts. I should have said that before, but only gave "xfstt --sync". Sorry. I thought it was a xfs problem, so i did run it. But now i checked my X output and it says "Could not init font path element unix/:7100, removing from list!". So xfs is not used! I think the problem was mkfontdir. I thought fc-cache (gentoo) would do this, but it does not seem so. Xfs did mkfontdir or something similar on all directories and so Dillo can find them now. Thats my assumption.
I checked .../fs/config and it is there. Thanks for help :D -- Andreas Zwinkau | web: andi.dasstellenwirinsinternet.de | mail: andi@buxach.de | jabber: beza1e1@amessage.de
