reproduce script

Finally, we found that the test cases killed X twice in a short time, which is the cause of this issue.

Update reproduce steps:

1.       Xinit&
2.       Python test.py
3.       Keyboard is freeze

The attachment is a script to reproduce this issue, please have a try.

The kill -9 probably happens before X has a chance to exit cleanly, so it doesn't unmute the keyboard (KDSBKMUTE) or changes the VT back to text mode.
