That commit makes hotkey emit notifications, and it's not the problem of "booting into a black screen", that problem is due to broken _BQC. BTW, the efaa14c will also make screen off at level 0 according to Felipe, who consider this is a bug. But since it is required to let firmware emit notifications on hotkey press, I think user will want it. -Aaron > > That being said, the blacklisting is still needed, because 1. the > level is not preserved between boots, and 2. level 0 turns off the > screen, which I personally consider a regression. > > At least it boots to level 100 instead of 0. > > -- > Felipe Contreras
