--- Comment #5 from XiongZhang <xiong.y.zhang at intel.com> ---
>From ODM's debug result, the root cause of the issue is PWM signal is changed
after suspend and resume in Linux no mater which panel is used. However BOE's
panel spec does not support well when PWM signal is 1.6K.
Why PWM signal is changed to 1.6K after suspend and resume?

=================================
In Ubuntu Environment: 
1. When system boot up to the desktop, PWM signal is 220K
2. After system suspend and resume, PWM signal is 1.6K

In WIndows 10 Environment:
1. When system boot up to the desktop, PWM signal is 220K
2. After system suspend and resume, PWM signal is 220K
===================================
