Your system is misconfigured and X races with an already running master process when it starts preventing it loading the right driver.
Comment 5 Jin Jing 2013-10-30 08:57:32 UTC 
so what's procedure to configure it correctly. Thanks

On second look, xf86-video-intel 2.19.0, does not support Baytrail. Generic support for Baytrail landed in 2.20.0, with specific support first in 2.20.8.
