[gentoo-user] Gallium and nVidia

[András Csányi]

Hi All,

I would like to some clarification to support my feeling regarding
gallium related use flags in mesa package.

For some reason I have to rebuild a few packages on my machine and
xorg-server and mesa are among them. I experienced that if the "xorg"
USE flag of mesa is enabled then I got compiling error. After a little
searching I could see that this use flag enables gallium3d.

My question is that, as a nvidia user - I have an nvidia card and I
use a nvidia driver from nvidia-drivers package - do I need this use
flag? Do I need the gallium related use flags in mesa?

Thanks in advance for any help!

András

Don't use gallium with nVidia's proprietary driver. Gallium is the
architecture used by mesa for all open source 3D drivers (intel, radeon,
nouveau, etc).

nVidia bypasses all of that and does their own thing.

I have "gallium" enabled and am also using nvidia-drivers. It doesn't do 
anything when running those drivers though. What it can do though is 
provide software OpenGL rendering, in case you need a fallback.

In any event, it doesn't conflict with nvidia-drivers, since it's not 
used if you did:

   eselect opengl nvidia

(Which I assume you did, since otherwise you wouldn't have 3D support 
with the nvidia drivers.)
