backlight flashes at booting.

[jebin]

Backlight flashes at booting. And booting enters into black screen with message "you need to manually fix graphics and video driver". Unable to fix it manually.

If the lcd screen is turned off during booting using (fn+f7) keys , ubuntu 16.04 boots without any trouble.

Suspend not working properly. laptop wakes automatically from sleep after 3 seconds.

The problem start in ubuntu 14.04 & continues in 16.04 also after downgrading to 12.04 & 13.10.
