Hi Justin,
OK, looks not just one problem on you machine. Let's clarify one by one:
+ For the Fn key you said:
<fn>+<brightness/volume/suspend/etc.> key combos not working
That a bit strange for at least the volume control (normally on Acer
machine are Fn+up/down) should work because it direct send out useful
scan code.
Please help to capture the scan code by showkey:
- Add atkbd.softraw=0 kernel parameter and reboot system.
- Switch to console and login with root account, then run:
# showkey -s
press Fn key and monitor the showkey output.
+ For we want to make sure acer-wmi causes any problem:
Please add acer-wmi to the blacklist of modprobe
(e.g. /etc/modprobe.d/blacklist), then try to reproduce all issues on
your machine. (Fn key, AC power...)
+ For brightness control:
Please check does there have /sys/class/backlight/acpi_video0 folder
on your machine. If you found it, please try to change the backlight by:
# echo 3 > /sys/class/backlight/acpi_video0/brightness
If you didn't see acpi_video0, please try 'acpi_backlight=vendor'
kernel parameter. Then /sys/class/backlight/intel_backlight should show
up on your machine if it used Intel graphics Adapter.
+ For the AC power problem:
Per your DSDT, the EC _Q37 is mapping to AC unplug and _Q38 is AC plug.
In _Q37 and _Q38, they notify AC, Battery and Processor acpi devices,
but I didn't see it changed backlight. Did you set S3 suspend when lid
close?
Thanks a lot!
