> We did a small experiment with nviz to find out what is the cause of
> crashes:

> we installed the latest cvs snapshot on 2 similar, single processor
> machines, one with Matrox, another one with NVIDIA graphics cards.

> There is no problem on machine with Matrox, however Nviz crashes quite
> often when opening or closing its widnows on machine with NVIDIA. Other
> functions in Nviz work very well  (Bob, the problems with masked out parts
> of surfaces is completely gone and the lights are much better, some buttons
> sometimes don't work quite correctly but I will write about it later). In
> an effort to fix the NVIDIA problem the student that I work with did the
> following:

> 1. Get rid of Mesa
> 2. Load the latest drivers from Nvidia
> 3. Create the directory /usr/include/GL and move all the files from
>    /usr/share/doc/NVIDIA_GLX-1.0/usr/include/GL to /usr/include/GL
> 4. Obtain the latest version of the glu set from www.mesa3d.org.  They
>    have a link to the rpm oss-opengl-glu-20000925-1.i386.rpm
> 5. Install oss-opengl-glu-20000925-1.i386.rpm
> 6. Install grass using the standard install scripts:
>    configure
>    make
>    make install
> Nviz still crashes - was this done correctly? When all Mesa stuff is
> removed Nviz does not run - it is looking
> for libGLU and Dave says that there is no libGLU for NVIDIA????
> (I appologize if this is a stupid question).
> IDL supposedly runs with open gl on the same machine without any problems.
> Do we have a problem in Nviz or is this purely NVIDIA driver and our
> mess issue? We have 3 NVIDIA PCs here crashing with Nviz which we
> would like to use for GRASS and Nviz, so it would be nice to find out
> how to fix this. I also assume that there will be more future users with
> NVIDIA cards so it would be useful to provide some hints on how to set it
> up with GRASS to avoid the crashes. Also Markus it would be good if you
> could include some notes with the release how you did fix the crashes that
> you had.

> Is anybody running GRASS on a PC with NVIDIA graphics card? Paolo, you
> were pretty close with your advice, do you have NVIDIA?
> thank you and I am sorry for bothering you again,
