Hi,

I don't think it is a libdrm issue (yet). By default the permissions on
the /dev/dri devices get set to 660 and root:wheel. So the question is
if your user can read the devices. If it is a permission problem,
FreeBSD 11.0 makes the /dev/dri/ devices part of the video group, so
just adding yourself to that group and relogging should fix the
permission issue.

I'm not sure if the video group fix was ported to FreeBSD 10.3, but you
can fix that by either making yourself part of the wheel group or
adding a line to /etc/devfs.conf to set the permissions to 666 on the
/dev/dri devices.
