XPS13 ubuntu 14.04 backlight

I have just update my XPS13 from ubuntu 13.10 to 14.04 and I have another time problems with the backlight with the last kernel (3.13.0-24). everything work find with 3.11.0-20, but with the last kenel, the backlight stay at low level. When I press the brightness key, I can see the animation but I doesn't do anything.

Have you got any solution to fix this problem?

Thanks

I have the early beta Sputnik, and my backlight works just fine after an upgrade from 13.10 to 14.04.

I don't see an animation at all, but I do see the backlight go from high to low to off as I hit Fn+F6

I need to add that I have a dual boot Win 8 and ubuntu 14.04 with EFI. It's not a single boot version

Thanks
