So far I've added the options acer-wmi ec_raw_mode=1 to a modprobe.d
conf file. Looking at /sys/modules/acer_wmi/parameters/ec_raw_mode
contains a Y. The mousepad remains unresponsive on boot prior to a
Fn+F7. I've added options acer_wmi ec_raw_mode=1 (note the acer_wmi vs
acer-wmi) simply because the sysmodule was also underscore. There is no
difference, the module parameter is recorded as Y and the mousepad still
does not work on boot.
I will provide the other requested information soon.

Hello,
I recently purchased an Acer Aspire One (model A0275-0691). It has an
elantech touchpad. As detailed in this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=848270 the acer-wmi driver
has two issues on this device.
#1) It is sending TOUCHPAD_TOGGLE and simultaneously changing state
#2) It disables the touchpad at init
So I tested the patch provided here.
https://bugzilla.redhat.com/show_bug.cgi?id=848270
It definitely allows the Fn+F7 key combo to toggle the use of the
mousepad. Unfortunately the mousepad comes up disabled and is very much
confusing the users using the device. Is there somewhere I should look
for what is causing that? I don't mind helping to debug the issue at all
I just don't know where to start.
Thanks,
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!
