I think backlight/brightness control is a separate issue, not sure though. I've
seen variance in backlight control of different kernels on the TX300 and it's
seemed to be quite separate from the issue in this bug report. I think part of
it is a separate asus_nb_wmi module.

Do you know of a patch or kernel version with which backlight/brightness
control works on the XPS 13?
