This is very similar to the problem I had on my Debian system from upgrading to
Xorg to 7.x from the 6.x system.  I found resources to help with that on this
list and at http://openfacts.berlios.de/index-en.phtml?title=FreeNX_FAQ/Server
It seems the basic problem was paths for the x server that disappeared in the
transition to 7.x as well as default font path settings in the
/etc/nxserver/node.conf settings...

Good Luck :)
