NV_CTRL_GVO_DISPLAY_X_SCREEN
/*
* NV_CTRL_GVO_DISPLAY_X_SCREEN - enable/disable GVO output of the X
* screen. At this point, all the GVO attributes that have been
* cached in the X server are flushed to the hardware and GVO is
* enabled. Note that this attribute can fail to be set if a GLX
* client has locked the GVO output (via glXGetVideoDeviceNV). Note
* that due to the inherit race conditions in this locking strategy,
* NV_CTRL_GVO_DISPLAY_X_SCREEN can fail unexpectantly. In the
* failing situation, X will not return an X error. Instead, you
* should query the value of NV_CTRL_GVO_DISPLAY_X_SCREEN after
* setting it to confirm that the setting was applied.
