-------------------------+--------------------------------------------------
NVIZ fails to start in any of the four GRASS versions on my computer.
Running Fedora 10, kernel 2.6.27.12-170.2.5.fc10.i686. I have GRASS-6.2.0
(compiled by me), GRASS-6.2.3 (compiled by me), GRASS-6.4.0-RC3 (compiled
by me) and GRASS-6.3.0-6.fc10 (installed from repository). All were
compiled/installed on 29 January 2009 with the OS updated as at that date,
using defaults for compiling. NVIZ in GRASS-6.0.2, GRASS-6.2.3 and
GRASS-6.4.0-RC1 ran fine in Fedora Core 5 back in December 2008 and/or
early January 2009. I upgraded from FC-5 to Fedora 10 (clean OS install)
on 26 January 2009. NVIZ failure to start noticed today, with all
available updates and bug fixes as at 3:00 pm Atlantic Time on 03 March
2009.
When running GRASS-6.2.0 and GRASS-6.2.3 by clicking the icon on the
display window, NVIZ stops at the tiny grey NVIZ screen plus tiny black
screen with red "please wait" (both stay up until I close the tiny
windows). Running NVIZ from the command line I get the following messages
for GRASS-6.2.0 and GRASS-6.2.3 respectively:
--snip--
Loading data
translating colors from fp
Update elev null mask
Loading data
--snip--
and
--snip--
ading data
Update elev null mask
Loading data
translating colors from fp
--snip--
When running NVIZ from GRASS-6.3.0-6.fc10 or from GRASS-6.4.0-RC3 by
clicking the display icons, the tiny NVIZ windows quickly flash on and
off.
When trying to run NVIZ from the pull-down menu in GRASS-6.3.0 I get this
error:
--snip--
nviz elevation=Site_plan_elevation3@Ocean_Links
Loading Data
translating colors from fp

Error in startup script: could not create rendering context
while executing

(file "/usr/lib/grass-6.3.0/etc/nviz2.2/scripts/nviz2.2_script" line
1045)

When trying to run NVIZ from the pull-down menu in GRASS-6.4.0-RC3 (either
from tcltk or the wxpython GUI) I get this error:
--snip--
nviz elevation=Site_plan_elevation3@Ocean_Links
Loading raster map <Site_plan_elevation3@Ocean_Links>...
Translating colors from raster map <Site_plan_elevation3@Ocean_Links>...

(file "/usr/local/grass-6.4.0RC3/etc/nviz2.2/scripts/nviz2.2_script"
line 1052)
--snip--
I have also run NVIZ in earlier versions of GRASS on Fedora Core 5 and
FC-2 machines, as well as as on Red Hat 7 and 9 machines, all with
success. The error messages above seem to suggest script issues (??),
unless there is a call somewhere that is Fedora 10 specific? One of the
bug upgrades applied via Fedora repository today was to tk libraries.
Can't tell whether this is the cause of the problem, however, as I have
not run NVIZ since upgrading to Fedora 10 in January.
Hope this information is useful. Beyond this, I'm at a loss, and cannot
think of anything else to add.

Rick
P.S. Grass Team, you have done and continue to do a wonderful job
