Please try 'ec_raw_mode=3D1' acer-wmi parameter to avoid acer-wmi run
launch manager mode. Run the following statement through root and reboo=
t
system:
	# echo "options acer-wmi ec_raw_mode=3D1" > /etc/modprobe.d/acer-wmi.c=
onf


On the other hand,
I checked your dmideocde on brc#848720, the 0x82 is the RIGHT acpi code
to you for touchpad_toggle key, that means acer-wmi should emit
KEY_TOUCHPAD_TOGGLE to userland. There have another thing also listen
the KEY_TOUCHPAD_TOGGLE and do the change. I checked the
gnome-settings-daemon, it just show up OSD but didn't change touchpad
status.

Could you please help provide the following information?
	+ please attach acpidump:
		# acpidump > acpidump.dat
	+ please help to capture acpi debug log:
		+ please remove ec_raw_mode=3D1 first.
		+ check your kernel parameter need enable: 'CONFIG_ACPI_DEBUG=3Dy'
		+ please add the following kernel parameter and reboot system:
			acpi.debug_level=3D0x0000000F acpi.debug_layer=3D0xffffffff log_buf_=
len=3D5M
		+ after system reboot, please press Fn+F11 (touchpad toggle key) a co=
uple of times.
		+ please attach on dmesg log.

=46or your backlight function key problem, please file another bug on
bugzilla.kernel.org.



Thanks a lot!
