[Alan E. Davis]

I am thorougly confused: things must be moving very quickly with xorg
7.  I hope my jumping in here will not further confuse the issue.  I
have found various descriptions of the roots of the problem, and
various solutions involving masking different combinations of
packages.  I had decided to drop back to "xf86-video-nv.

Neil, you have masked
    >=f86-video-nv-1.1.2

Wow.

I have been having another problem that I'm uncertain would belong in
this thread: I got rid of nvidia-kernel and nvidia-glx altogether,
much to my regret because they are faster.  Now when I emerge -uDv
world, the system wants to pull these in again.  I have traced the
problem, unbelievably, to xine-libs: my ebuild required some USE flag,
I think.
   In /usr/portage/media-libs/xine-lib/xine-lib-1.1.2_pre20060606-r3.ebuild
I find:
      IUSE_VIDEO_CARDS="video_cards_nvidia video_cards_via video_cards_i810"

Thus I have two more questions:

    1. Is this the ebuild that is pulling nvidia-kernel and nvidia-glx
back in?  (I already unmerged nvidia-settings).

    2. Is it even possible to run nvidia-kernel?  Is the "nv" driver
all that bad, or is it possible to get it to work decently with
opengl?  Is it possible to work with new nv drivers?

   Also, there is the parameter in /etc/make.conf:
        VIDEO_CARDS="nvidia"
Should this be dealt with?  I did this when following a howto about
migrating to modular xorg.

I apologize for crashing this thread, especially if somehow I have
misunderstood.

This is being pulled in because you have VIDEO_CARDS=nvidia in
/etc/make.conf.  If you want only the opensource nv driver, you want
"VIDEO_CARDS=nv" instead.

The nv driver does not support DRI (eg, no 3D hardware acceleration),
so opengl applications are going to run in software emulation mode,
and probably be very slow.

What is it that you are trying to do?

Ok, I'll try this.  What's IUSE="video_cards_nvidia ... etc " all
about in the xine-lib ebuild?

Watch and edit videos, for one thing.  Googleearth.  Grass gis maybe.

Nv has been ok.  W/ dual opterons, even though not especially fast
ones, these graphics intensive tasks have been performing well.
Googleearth hasn't been working, either because of this issue, or
amd64 incompatibility: it works well even with a really slow card on
an x86 box.

Thanks for the pointers.

Googleearth will be very slow without opengl acceleration, so you
probably want to stick with the nvidia driver.

You should verify that DRI is being activated with glxinfo (should
see: "direct rendering: Yes".  Also make sure that "eselect opengl
list" shows nvidia as the selected implementation.
