[GRASS5] RE: [bug #4140] (grass) Nviz doesn't start either from GUI or CLI

[Luigi Pirelli]

Hi,

could you send more detailed information with:

from CLI

ddd nviz
 > r elevation=Cheticamp98.5.ave.fill
(ddd or dbx or aother debugger)
.
.
.
.
after Seg fault type:

 > where
cut&paste result of the stack

please control all linked libraries using command ldd of the nviz and related 
loaded shared object.

sometimes nviz doens't start when 3d support driver is not loaded... please 
check if correct Graphic Card Driver is loaded... las saturday, nvidia drivers 
whas't able to be loaded due to a flag in xorg.conf when PC was using a 
particular projector...
