[gentoo-user] Why sci-libs/vtk asks for media-video/nvidia-settings ?

[Francisco Ares]

Hi, and happy new year to all.

I have a not so old nvidia video board, but the recent closed source driver
complains, saying that I should stick to an earlier version:

x11-drivers/nvidia-drivers-340.93-r1 (it is recommended if I unmask it and
emerge a new one)

Then, in an excerpt from emerge -tpvuDN world:

...

What should I do?  Although not entirely satisfied in using a closed-source
driver, and as far as I know, the alternative xf86-video-nouveau isn't as
complete.

Any ideas?

Thanks a lot and best regards,
Francisco
