With 3.8.0-18 kernel, brightness control is not working on my XPS13 with raring. Blacklight is on but at minimum, brightness keys do nothin. Blacklight is perfectly working with kernel 3.8.0-17 and maybe before: on waking from suspend, brightness is restored as before suspending and is adjustable. So this fix seems to solve the bug for someone, but introduced a new bug for me that I had no problems before. My laptop is an XPS 13 last model, with full-hd display. I installed raring from scratch and it is booting with uefi.
