[gentoo-user] major problem involving nvidia drivers, gnome and x

Hi.  I normally do updates approximately monthly and I use the gnome
overlay, so I get the latest gnome.  I am also using ~amd64 version of
gentoo.

Now, this time when I went from version 4.1.17 to 4.1.20 kernel  and did
my monthly update at the same time, two things happened.  On the 4.1.17
kernel, if I try to start gdm, I get a blank screen.  Logs look good in
that the screen is detected and the gnome session runs, but I get a
blank screen.  This is true even if I use startx instead of starting
gdm.  Now with 4.1.20 the nvidia drivers I am using get an invalid
argument when trying to modprobe it.  Its version 355.11-r4.  If I try
the latest version, I get modeset errors, although it stops giving me
the invalid argument.

So, I have really two separate problems here, the blank screen and the
nvidia driver problem, either one of which makes X totally unusable for
me.

Any thoughts on this matter would be appreciated.
