..I know. Problem is, I don't know. ;-) The message id's tells me

..ok, how do I weed out one from the other?
Specficly, how do I get maximum verbose debugging in FG?

Name : Mesa Relocations: /usr
Version : 3.4.2 Vendor: Red Hat, Inc.
Release : 3 Build Date: Tue 10 Jul 2001
11:38:22 AM CEST
Install date: Sat 21 Jul 2001 01:27:07 PM CEST Build Host:
stripples.devel.redhat.com

Summary : A 3-D graphics library similar to OpenGL.
Description :
The Mesa 3-D graphics library is a powerful and generic toolset for
creating hardware assisted computer graphics. To the extent that Mesa
utilizes the OpenGL command syntax or state machine, it is being used
with authorization from Silicon Graphics, Inc. However, the author
(Brian Paul) makes no claim that Mesa is in any way a compatible
replacement for OpenGL or associated with Silicon Graphics, Inc. Those
who want a licensed implementation of OpenGL should contact a licensed
vendor. However, Mesa is very similar to OpenGL, and you might find
Mesa to be a valid alternative to OpenGL.

..thanks Cameroon, Wolfram and Norman.
As a linux user who has run _out_ of ideas, I am
now ready for the weird stuff I havent tried yet, now.
Like having you guys rewrite things in FG. ;-)

Scenarios always come in sets of three:
best case, worst case, and just in case.
