hello

i' m try to install nvidia-drivers latest on gentoo 4.8.11 gcc compiler 5.4.

i've compiled kernell with genkernell, the driver has compiled, but not
work because kernel conflict, i recompiled the same kernel following the
istruction on handbook, but when i try to emerge nvidia driver portage fail
to compile.

i try also to find the problem to add or remove graphics and firmware
correlated features by menuconfig, and recompliling kernel.

the result is:
the module nvidia.ko missing some value:

lib/modules/4.8.11-gentoo/video.ko needs unknown symbol:

Try rebuilding the nvidia driver.
A good way of dealing with this and other modules is:

emerge -va1 @module-rebuild

Maybe you are stripping unneeded symbols? Try to recompile the kernel
without this option first.

Curiosity : At one point the ( x11-drivers/nvidia-drivers ) package was
reporting during build, kernels higher than 4.4 were not supported (
nvidia's policy ). Has that changed?

According to portage git changes: Yes. And it looks like the warning is
no longer reported for 4.8 as it works for me - no warning reported and
no user patches applied to kernel.

on ~amd64 x11-drivers/nvidia-drivers, are supported to kernel 4.8; i not
find any warnings.

Then post the error that you're getting and the output  of the
pre-emerge checks.

If you build your kernel with genkernel it *should* work. You probably
just had to blacklist the free drivers to resolve the "kernel conflict".
So maybe start over with a fresh genkernel and try that.

That's expected if you didn't recompile the drivers. It means that one of
the features you disabled was used by the driver module. Also make sure
you remove the /lib/modules/4.8.11-gentoo directory before reinstalling
your kernel modules as it looks like video.ko is not supposed to be
there. Maybe you disabled that feature but the modules is still there
from your previous build.
