Dear all,
Apologies if this has been covered elsewhere. Please also note that I am new
to Linux and GRASS (less than 4 days!!) - so it is safe to assume that I
know nothing!.
I have managed to get GRASS6 up and running on fedora core 5 (after some
"fun" installing tcl/tk libraries). When I enter Nviz and try to display the
elevation.dem from the Spearfish60 sample dataset the visualisation appears
for about 10 seconds and then disappears - no error messages are reported to
help sort the problem. The control window is empty.
I may have confused the software with my tcl/tk installation antics - I now
have both tcl/tk 8.4 and 8.5 libaries in my /usr/lib directory but only the
8.4 library is reported when I test the installation in the command window.
I do not know how to uninstall 8.5 (I could not get GRASS to work with the
8.5 libraries). Is this the source of my problem or am I completely missing
the point?
Any help with what to try next would be greatly appreciated.
Many thanks
Darrel

What happens if you issue the 'nviz elev=elevation.dem' from CLI?
Please copy/paste the text output here (tcltk GUI tends to hide some
low level errors, like segfault, from the user).
Do you know that you must set the region to match the elevation.dem
first (g.region rast=elavation.dem) for NVIZ (and most any other
display module) to be able to display it?

Grass supports 8.3 and 8.4.
As to removing your 8.5 instalation - did you install it using rpm? On
Fedora, 'rpm -e thepackage' or 'yum' equivalent should do it (read 'man
rpm', 'man yum').
