Is this supposed to be fixed? I have XPS13 (Feb 2013 edition, i7) with latest saucy 3.11.0-15 and problem is still there.
Last kernel that works properly is
Linux slap 3.8.0-29-generic #42-Ubuntu SMP Tue Aug 13 19:40:39 UTC 2013
which I am running right now, while the system is upgraded to Saucy and the kernel is one used in the 13.04 series.
To be precise: the brigthness buttons make the brightness bar appear on screen and go up and down correclty, but actual brightness is always at the lowest possible level, never changes.
