13104	vaapi fails to initialize under wayland	Stuart Auchterlonie	Stuart Auchterlonie	"When starting playback on Fedora 26 on VAAPI capable
hardware, the vaapi libraries fail to initialize
properly, and we fall back to software decode.

Switching back to Xorg, rather than Wayland and vaapi
works correctly again.

Under Wayland:
{{{

libva info: va_getDriverName() returns -1
libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)
