Hi, I don't, no. I haven't dug further into the i915 backlight control code because, well, a lot of changed in that update. The backlight code was in a lot of flux during the period of time kib chose to fast forward, so it's not unsurprising that it broke for some. I think for now we'll need a quirk that can be added for each laptop we find with that particular behaviour. The real solution is to continue sliding i915 forward in time. -adrian _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
