@Koos I have almost the exact same setup, except not sure about the UEFI

I assume you don't have a xps13 full HD as 3.8.0-30.44 makes the backlight
work in my xps13 full HD (it stopped working after 3.8.0-20.31).

Chris,
It is true that I haven't posted anything lately, but many others have
taken up the slack. The XPS 13 is my primary computer and I had to switch
back to Windows because of several bugs (including this one) that were
causing me to spend more time troubleshooting than getting actual work
done
"there hasn't been any activity in it recently"

Kernel 3.8.0-30 broke brightness control in my case.
I have an IvyBridge fullHD XPS13, BIOS version A08, with Ubuntu 13.04 booting
in UEFI mode with Legacy Option Rom disabled.
Actually, with this configuration brightness control was broken in 3.8.0-18,
fixed in 3.8.0-20, broken again in 3.8.0-21
Just got a new kernel on 12.10, and backlight control is lost.

Daniel, did you actually reinstalled Ubuntu in UEFI mode? because it

help. Your system still boots in Legacy mode. You have to have Ubuntu
