I think it failed because I replaced an Intel motherboard with an AMD board 
and I get this from dmesg:

[    9.194493] NVRM: The NVIDIA GeForce 8400GS GPU installed in this system is
               NVRM:  supported through the NVIDIA 340.xx Legacy drivers. 
Please
               NVRM:  visit http://www.nvidia.com/object/unix.html for more
               NVRM:  information.  The 375.66 NVIDIA driver will ignore
               NVRM:  this GPU.  Continuing probe...
[    9.194498] NVRM: No NVIDIA graphics adapter found!

I haven't rebooted the machine for almost 2 years until I replaced the mb and 
this is the first I've seen of this message - it's always Just Worked.

I understand that the Radeon does VDPAU though...

I'm quite out of my league here...
