Knoppix 5.0.1 HDD and vncserver font problem

Hello,

I recently installed two different copies of Knoppix 5.0.1, but in neither of them I am been able to start vncserver.

I tried with version 3.3 and 4.0 of vncserver, but I have the same problem: Could not open font "fixed"

22/10/06 10:35:53 Xvnc version 3.3.7 - built Aug 9 2006 08:33:03

Fatal server error:
could not open default font 'fixed'

Any ideas?

I also tried to install also xfs and xfs-tt and configure the vnc.conf accordingly, but no result.

Marco.
