[Libva] using libva video compression on system with no monitor

Wed Aug 15 04:02:10 PDT 2012

I am using fedora core 16.
Yes I have full sudo access, but I don't want to have to run as sudo.

The display does not get "authenticated" when I run with just my user name.

Which OS? If debian, granting access to non-root users in /etc/sudoers
file does not do it?

%my-username   ALL=NOPASSWD: ALL
