I think there is another bug in the intel-graphics on my dell xps13 9333.
when i do  a $ sudo apt-get install kubuntu-desktop ... use of lightdm ... the sceen shows white  patterns like " ||||    ||||    ||||    ...".
I've changed the greeter to unity(ubuntu) -> the same problem.  In some cases the upper mentioned pattern is on the whole screen (Black), an even when changing the console to F1 (console works) and going back to F7 the effect remains. After a reboot i have the pattern again and cannot login on F7. 
I've the sputnik kernel      3.5.x  and use the ubuntu 12.04 delivered from dell. newest updates where done.

Bug description:
  The backlight brightness is not changeable by default on a Dell XPS 13 running Precise beta 1 (or later). If I run the following command as root, I can adjust the brightness:
      /bin/echo 0 > /sys/class/baclight/intel_backlight/brightness
  However, I must do this whenever I turn on the computer or resume it from suspend.
