Bug Description

On a 64-bit Ubuntu 12.04 system, a 32-bit application doesn't find the NVIDIA VDPAU accelerated driver in /usr/lib32 by default.

I discussed this with Alberto Milone, and he writes:
The fix is trivial. It's just a matter of adding the /usr/lib32/ path in /etc/ld.so.conf.d/x86_64-linux-gnu_GL.conf (or in /etc/ld.so.conf.d/i386-linux-gnu_GL.conf).

Here's what ldconfig currently says in my chroot:
# ldconfig -p | grep pau
        libvdpau_nvidia.so (libc6,x86-64, OS ABI: Linux 2.3.99) => /usr/lib/libvdpau_nvidia.so
        libvdpau.so.1 (libc6,x86-64) =>

This is what I get after I add the line that I mentioned:
# ldconfig -p | grep pau
        libvdpau_nvidia.so (libc6,x86-64, OS ABI: Linux 2.3.99) => /usr/lib/libvdpau_nvidia.so
        libvdpau_nvidia.so (libc6, OS ABI: Linux 2.3.99) => /usr/lib32/libvdpau_nvidia.so
        libvdpau.so.1 (libc6,x86-64) =>

On a second thought, it's probably best if we simply add a dependency on libc6-i386 (on amd64) as we already do in fglrx

I installed nvidia-graphics-drivers-304-updates and nvidia-graphics-drivers-304 from proposed (on Ubuntu 12.04 Precise) and intense test it (by playing games on Steam).
It works perfeclty for me.
