[Bug 1837117] [NEW] Laptop backlight is off after system boot up

Public bug reported: After kernel update the backlight on my Asus eeepc 1005px becomes off during boot up. I can see the login screen if I point light to the screen. The backlight is not reacting on brightness adjustment keys. The backlight starts working only if I close and open the laptop lid.
