<pre>after running command "xinit &" to start X window, system should display X
window on the monitor automatically.
notes:
1. not all BDW machine can reproduce this issue.
2. if this issue arise, even uses older kernel and older X11R7, it also can
be reproduced.
(for example: kernel:20140227_nightly and X11R7:20140227_stable)
1. Testing Env:
========================================================================
kernel: 3.15.0-rc5_drm-intel-fixes_4ba480_20140521
X11R7: X11R7.stable.2014-05-20.tar.gz
2. Testing Steps:
========================================================================
1.boot up system
2.running cmd "xinit &" to start X window
3.check the the monitor, the X windows cannot display
workround:
1.after running "xinit &", run command "ps aux |grep X" to check which
tty are using by X(for example:tty2 )
2.run command "chvt 2"
3.check the the monitor, the X windows can display now.
3. Debug Information:

3. Frequency of Occurence:
========================================================================
machine 1：Test 5 times, and this issue arise 4 times.
machine 2：cannot reproduce this issue.</pre>
