Sorry for my bad english. I have a problem with VDPAU: when I use sudo vdpauinfo or sudo nvidia-settings all works fine. But when I use only vdpauinfo or nvidia-settings it is not supported anymore. I tried the vlc-wrapper on supermode and it worked. How can i enable VDPAU on a non supermode user? I have ubuntu 17.04 and Linux Driver v384.69.
Something is wrong with your access rights.
I’d recommend that you reinstall your distro from scratch.
I installed Linux Mint. Now all is fine. :)
