Wait, I also have the mesa- stuff installed:

    i   mesa-vdpau-drivers      - Mesa VDPAU video acceleration drivers
    i   mesa-vdpau-drivers-dbg  - Debugging symbols ...

Perhaps there is some mismatch at work?

What card do I have? What drivers do I need? How do
I tell mplayer (the whole system?) to use that and
nothing else?

Card:

    $ lspci | grep -i vga
    00:02.0 VGA compatible controller: Intel Corporation
    Haswell-ULT Integrated Graphics Controller (rev 0b)

Drivers:

    i   libvdpau-va-gl1  - VDPAU driver with OpenGL/VAAPI backend
    i A i965-va-driver   - VAAPI driver for Intel G45 & HD Graphics

Invocation:

    VDPAU_DRIVER=va_gl (or '-vo gl')

Did I forget anything or should it work?

If it doesn't work, can I reinstall anything (e.g., X)
to purge a misconfig down the road if that is
the hypothesis?
