After doing the following I didn't notice any difference and the nvidia
driver wasn't installed in the first place.

First)

Second)
echo ">=x11-drivers/nvidia-drivers-177.0.0" >> /etc/portage/package.mask

Third)
modprobe has nothing to do.
# modprobe -rn nvidia

Original opengl setting
# eselect opengl list
Available OpenGL implementations:
  [1]   nvidia
  [2]   xorg-x11 *

Restarted and nothing changed.

fourth)
# eselect opengl set nvidia
# eselect opengl list
Available OpenGL implementations:
  [1]   nvidia *
  [2]   xorg-x11

Restarted and nothing changed.

Do I need to set the resolution somewhere?  I haven't used an xorg.conf
file in sometime.

Thanks,
