Brightness control not saving setting between boot

[Anil Gobburi]

I bought a Dell XPS 13 recently and the brightness adjust shortcuts are showing the graphics on top left of the screen that the brightness is getting changed but I am not seeing any change in the actual brightness.

My issue is that the brightness setting resets after reboot.

I am able to change the brightness now. BUT the setting of brightness is reset after a reboot. It is not persistent.

Pretty sure there's a duplicate of this bug out there. For now, I'm marking as confirmed. This issue exists on my Lenovo Thinkpad X220, but there certainly is a workaround.
