I have an Nvidia GeForce 940M GPU in my laptop:
$ lspci -nn | grep NVIDIA
04:00.0 3D controller : NVIDIA Corporation GM108M [GeForce 940M] [10de:1347] (rev a2)
I use the proprietary nvidia driver version 387.12:
$ nvidia-smi | head

+-------------------------------+----------------------+----------------------+
According to the driver documentation , VDPAU features of my GPU should be supported.
Yet, when I actually try, it fails:
$ vdpauinfo
display: :0 screen: 0
GPU at BusId 0x4 doesn't have a supported video decoder
Error creating VDPAU device: 1
Naturally, media players can't use hardware acceleration either. What am I doing wrong?
