VDPAU support only as root

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.

Thank you.
I installed Linux Mint. Now all is fine. :)
