Comment 3 for bug 767192

A quick note regarding the acer-wmi driver and your hotkey.

That driver should support your machine, but it won't load automatically due to a typo (incorrect capitalization) in the wmi guid within the driver. This can be easily fixed. Your logs show that it loaded successfully (I'm assuming you loaded it manually in this instance), but then I see some errors from the AML parser from execution of one of the wmi methods. That's seems likely to be a bios problem, but I'm not sure right now what the implications are.

You won't see the Acer wmi hotkeys device in lsinput because the wmi event guid the acer-wmi driver uses doesn't exist on your machine. The hotkeys may be reported on your AT keyboard device, and some may generate ACPI events and no key events. To check, use lsinput to find your AT keyboard device, then run:

  sudo /lib/udev/keymap -i input/event<n>

where input/event<n> corresponds to the device you found with lsinput. While this is running, press your wifi hotkey. Then do the same while running:

  acpi_listen

Thanks!
