I'm starting to get really curious as to whether either pBuffers or
GLX Pixmaps actually work for *anyone*.
It does no longer work for me (it did in the past):

A pity! Also the volume was broken apparently in May 2006.
The quality of NVIZ seems to be continuously decreasing
which isn't nice.

Markus, Brad, does this work for you in 6.1.0?
In 6.3 if you do:
If they don't work, you can turn them off:
export GRASS_NO_GLX_PBUFFERS=1
export GRASS_NO_GLX_PIXMAPS=1
?
As the problem appears to be widespread, I propose to disable off-
screen rendering for the 6.2 release branch and work on fixing the
problem in 6.3-cvs.

NVIZ volume + NVIZ highres output fail in 6.1.0.
I would need a version before May 2006 to see if it was broken
by the togl update and related changes.
I have a February 2006 CVS on my Mac, but I need to finish my talk first, then I can test,
hopefully later today or tomorrow, unless somebody else responds too.

This is a different issue.
I note that Nstart_zoom_cmd() only uses a 64-byte buffer for the
prefix; you may be overflowing that.

That's probably inevitable. The complexity of NVIZ/OGSF is such that I
doubt that any GRASS developer really understands it.
