Acer Aspire 5733 - acer_wmi problems

[Justin Chudgar]

[-- Attachment #1: Type: text/plain, Size: 1837 bytes --]

I have an Acer Aspire 5733 that is having issues with:
- <fn>+<brightness/volume/suspend/etc.> key combos not working
- screen not resuming when unplugging/replugging a system while system
continues operating

Could someone please help me determine how to triage these and direct me
on what info the maintainer needs from me.

Thank you.

Hi Justin,

the disassembled DSDT always helps as a first step.

1. install "iasl" or get and compile the source:
https://www.acpica.org/downloads/unix_source_code.php
2. cp /sys/firmware/acpi/tables/DSDT dsdt.aml
3. iasl -d dsdt.aml

This creates a "dsdt.dsl" file. This is the interesting one.

Furthermore, check the kernel bugzilla if there isn't a similar bug
somewhere already.
http://bugzilla.kernel.org

This article is also good literature how WMI drivers work:
http://lwn.net/Articles/391230/

Also check for latest /lib/udev/keymaps/ and
/lib/udev/keymaps/force-release/. On this page this helped e.g. on a
Samsung laptop: http://blog.nonobis.nl/?p=11

Cheers,
Sebastian

Btw.: with "evtest" you can check if the scan codes of the missing keys
are sent when pressing them.
Then, it is just a key mapping issue and not an ACPI issue.

Scan codes need to be mapped to key codes.

Here is an example:

Re: Fwd: Acer Aspire 5733 - acer_wmi problems

[joeyli]

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!
Joey Lee
