(Get the code!)
On both versions of the XPS 13 (L322X and L321X) running Ubuntu Raring with the latest 3.8 kernel, letting the screen turn off and then back on causes the backlight to go to maximum brightness and become not adjustable. This behavior is not seen with suspend/resume or at boot (such as with LP #954661). I have verified this behavior on two systems. The backlight behaved correctly on both with Precise running Kamal's special kernel build.
