help, X & 'fixed' font

[Xingguo Pan <pan@anninghe.princeton.edu>]

My X window refuses to start because of a fatal error:

       could not open default font 'fixed'.

I'm using debian testing. After x crashed, I reinstalled 100dpi
fonts and x-window-system-base. I checked with /etc/X11/XF86Config-4
and couldn't find anything suspicious. However, shortly before the
crash, I played with locale in KDE 2.2.1 and apt-get update&upgrade
the system.

Has anyone met similar problem before?

Thanks in advance for your help.
