making fonts available for KDE

I installed about all the available fonts with synaptic. No specific configuration. I can find them with xfontsel. But I can't manage KDE to use them. Konqueror for instance. One of them (the fonts) is 'Adobe symbol', and I can't (don't know how to), make Konqueror use it, find it in it's list.

icons on desktop

I do align the icons horizontally. And it does. But when I restart KDE, it has forgotten the room (location?) they should be. I made grep on .kde/ but I haven't find things that would be the icons locations. Is there such a file? Christophe
