Dropping libva list since the problem isn't related to libva at all.
Adding the [email protected] list instead.
Something is indeed wrong with your DDX installation. Please provide the
X log, usually found under /var/log/Xorg.0.log.

Christian,
Thank you for taking an interest... as you can see from the output of
glxinfo [1], I've definitely got a problem, given that it's clearly
trying to use swrast_dri.
I did some reading about DDX [2], since that's the first time I've
seen that term. From what I can tell, my system is pretty hosed using
either glamor or EXA for hardware acceleration - both settings still
result is glxinfo not finding the radeon dri driver (which I checked,
and _does_ exist at /usr/lib/xorg/modules/dri/radeon_dri.so).

I don't see anything not working correctly off hand (except for
the obvious error message).
What's the output of gfxinfo? And does glxgears or any other
trivial 3D example work properly? Maybe the DDX isn't working
correctly.

Christian, the OP has vdpauinfo output (as well as a strace).
Attached is my dmesg.

Hello All,
I've been troubleshooting an issue with VAAPI + VDPAU and my
ATI Radeon HD7750, on Arch Linux with the following packages:
libva <https://www.archlinux.org/packages/extra/x86_64/libva/>
libvdpau
<https://www.archlinux.org/packages/extra/x86_64/libvdpau/>
libva-vdpau-driver
<https://www.archlinux.org/packages/extra/x86_64/libva-vdpau-driver/>
ati-dri
<https://www.archlinux.org/packages/extra/x86_64/ati-dri/>
xf86-video-ati
<https://www.archlinux.org/packages/extra/x86_64/xf86-video-ati/>
Namely, I cannot get the configuration to work as expected,
and both vainfo and vdpauinfo error out, as does XBMC, which
is my end-goal for getting hardware acceleration working.
% export DISPLAY=:0
% export LIBVA_DRIVER_NAME=vdpau
% export VDPAU_DRIVER=radeonsi
% vainfo
libva info: VA-API version 0.35.1
libva info: va_getDriverName() returns -1
libva error: va_getDriverName() failed with unknown libva
error,driver_name=(null)
vaInitialize failed with error code -1 (unknown libva
error),exit
zsh: exit 3 vainfo
% vdpauinfo
display: :0 screen: 0
Error creating VDPAU device: 23
zsh: exit 255 vdpauinfo
Attached are strace outputs.
Furthermore, in my completely n00b attempt to figure out
what's going on, I've stepped into the code using gdb, and
tried to trace where the failure is... and it looks to me
like no matter what I tell libva, it ALWAYS goes looking
for libatiadlxx.so, which is the proprietary ATI drivers.
Any help on how to proceed with my troubleshooting? I've
read through the documentation in va.h and the API diagram,
and am trying to wrap my head around how the various
pieces-parts go together and move around each other, and I
have to say I'm feeling a bit overwhelmed. It's all very
fascinating, but not my normal digs, so I'm hoping one of
you can give me some guidance on how best to run this down,
and hopefully turn this into a patch if it's not too
difficult... or a hopefully good bug report if a patch is
beyond me.
Regards,
Richard
