KDM doesn't start on boot up

[Jose Gomez-Dans]

Hi all,
This is a problem which has been cropping up intermittently in my
laptop. For some reason, KDM doesn't start on boot up. This occurs
when I move my laptop from home to work, which means going from a dhcp
configuration (wlan0) to a manual eth0 configuration, which forces me
to type in the /etc/resolv.conf values in every time after I stop
using the dhcp-configured network. I mention this because it could be
part of the problem.

The relevant error from Xorg.0.log is here:
Warning: font renderer for ".pcf" already registered at priority 0
Warning: font renderer for ".pcf.Z" already registered at priority 0
Warning: font renderer for ".pcf.gz" already registered at priority 0
Warning: font renderer for ".snf" already registered at priority 0

Warning: font renderer for ".bdf.gz" already registered at priority 0
Warning: font renderer for ".pmf" already registered at priority 0
Could not init font path element unix/:7100, removing from list!

Fatal server error:
could not open default font 'fixed';
the X server's font paths might be misconfigured, remote font server(s)
may be unreachable, and/or local fonts may not be installed or are not
configured correctly.

People inexperienced with the X Window System should have either the
"x-window-system" or "x-window-system-core" packages installed.
# apt-get install x-window-system-core
# apt-get install x-window-system


Many thanks!
