Comment 18 for bug 901410

@Fuad- Yes, you should file a new bug for each separate problem you encounter, after searching to see if it has been reported already. For what its worth, on my Dell XPS13z with the fixed kernel (comment #17), my system does correctly "remember" the wifi switch state after a reboot. But as you noted, the screen backlight brightness does not get preserved -- I believe that issue is very common, not specific to just the Dell XPS models.
