Please try 'ec_raw_mode=1' acer-wmi parameter to avoid acer-wmi run
launch manager mode. Run the following statement through root and reboot
system:
# echo "options acer-wmi ec_raw_mode=1" > /etc/modprobe.d/acer-wmi.conf
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=1 first.
+ check your kernel parameter need enable: 'CONFIG_ACPI_DEBUG=y'
+ please add the following kernel parameter and reboot system:
acpi.debug_level=0x0000000F acpi.debug_layer=0xffffffff
log_buf_len=5M
+ after system reboot, please press Fn+F11 (touchpad toggle
key) a couple of times.
+ please attach on dmesg log.
For your backlight function key problem, please file another bug on
bugzilla.kernel.org.
Thanks a lot!
