Nvidia Driver Issue: Held Broken Packages

[Joshua Blagden <jfblagden@gmail.com>]

I've been trying to get Blizzard's Battle.net app working on Debian 9. I have a GT 1030 in my PC and I installed the nvidia-driver package from stretch-backports because the regular version didn't work my GPU. After a lot of help from folks in the Debian IRC channel, I got nvidia-driver working (issues with headers, etc). I'm still having trouble getting Battle.net working. I can get it installed and I can have it install StarCraft II. But when I try to launch StarCraft II from the Battle.net launcher, I get an error message about not being able to find a graphics context.

I would assume the graphics context error points to me needing a newer version of nvidia-driver. But when I try to upgrade that package, I get error messages about broken packages. Here they are:

The following packages have unmet dependencies:
 libglvnd0-nvidia : Conflicts: libglvnd0 but 1.0.0+git20180308-2~bpo9+1 is to be installed
                    Conflicts: libglvnd0:i386 but 1.0.0+git20180308-2~bpo9+1 is to be installed
 libglvnd0-nvidia:i386 : Conflicts: libglvnd0 but 1.0.0+git20180308-2~bpo9+1 is to be installed
                         Conflicts: libglvnd0:i386 but 1.0.0+git20180308-2~bpo9+1 is to be installed
 nvidia-driver-libs : Conflicts: libglvnd0 (> 0) but 1.0.0+git20180308-2~bpo9+1 is to be installed
                      Recommends: nvidia-driver-libs-i386
                      Recommends: libopengl0 but it is not going to be installed or
                                  libopengl0-glvnd-nvidia but it is not going to be installed
                      Conflicts: libglvnd0:i386 (> 0) but 1.0.0+git20180308-2~bpo9+1 is to be installed
E: Broken packages

What can I do about this? How can I resolve this?

Thank you,
