dmesg file
I have a board based on Intel Atom E38xx (Bay Trail), if I plug HDMI/DP and an
eDP, when I control the brightness value, I see some flicker on eDP.
Other problem is about S3 state(standby), when I return from standby, the eDP
is off and my board freezes.
If I plug only the eDP, I don't see any bug, the brightness control works fine
and the S3 state works fine.
System information :
- system architecture : i686
- kernel version : 4.4.0-rc2+
- linux ubuntu 15.10
- display connection : HDMI/DP and eDP
