Hi,
I don't know . Unfortunately the drm2 update landed in between some
backlight changes in upstream ,and it's quite possible that we've hit
some magic point in the linux history where the backlight broke for
various versions of laptops.
It's fine for all the models I own, so unless someone buys me one so I
can tinker with it, you're going to have to wait for the next drm2
update to more recent Linux code.
