As I am the one who said to blacklist 3D apps, I will explain.
No 3D hardware support, your software won't work. It doesn't
matter
what you do or how often you install the software or attempt to edit
config files, will it work. It requires 3D support. It should or could
be a requirement before YUM installs the application.
To save the confusion, if a user doesn't install 3D video drivers, they
shouldn't be allowed to install 3D applications. I have run into it
many times already.
I do agree with you about different distributions. I don't recommend
Fedora to anybody that doesn't have some experience with Linux.
I would really appreciate it if nVidia, ATI or Intel would create RPM's
for their own cards so we could deal with them directly. Of course if
you have a bug, then you have to remove the driver to get any support.
Of course if the problem is in an application that requires 3D you are
hooped.
What stops Nouveau from being tested against Blender, various rendering
engines and Varicad, bog standard widely accepted 3D apps, then
released as fully functional before this discussion eventuated.
To sumarise: In the interim,
Use Fedora and distributions with Nouveau for 2D.
Use Windows, Sun or Apple for 3D modelling, design and rendering.
