This revised patch works correctly for me.
... and changing backlight brightness worked with acpi_osi=Linux, too. Unfortunately, that does no longer work now, although I haven't changed anything. Pressing the brightness buttons causes some ACPI debug output, but it doesn't adjust anything.

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
