hmm........ Takashi's patch works before, but doesn't work now? Does that because my new patch for bko#34142 ? Could you please add acer-wmi to /etc/modprobe.d/blacklist then reboot machine ? Step: - add acer-wmi to /etc/modprobe.d/blacklist - shutdown your machine - remove AC power and notebook's battery - plugin AC power then boot your notebook - check the brightness control Thank's Joey Lee
