my startx produces a message:

"Couldn't init font path element /usr/X11R6/lib/X11/fonts/TTF, .....

but actually I can use my TrueType fonts without problems.
However, I doubt that's the reason why I cannot use those fonts in conventional X applications. So how should I configure the font path?
Besides, it seems that the XF86Config is not necessary in pdaxrom? I cannot find one under /etc/X11.
