[Bug 713278] Re: Touchpad Hotkey not working on Asus V6

[bdoe]

I'm running Linux Mint 11 "Katya", which is based on Ubuntu 11.04 Natty.
I just tried the trick in reply #5, adding the hotkey to gnome-
keybinding-properties, and the Fn+F9 combination finally works to enable
and disable the touchpad on my Asus G73JH laptop. I did not have to edit
or alter /etc/acpi/asus-touchpad.sh at all.

What I find interesting is that the hotkey event handler
/etc/acpi/events/asus-touchpad does not appear to work at all, even
though it has the proper hotkey definition according to acpi_listen. As
far as I could tell, the hotkey was not being trapped at all. With
Ubuntu 10.10, I had the opposite issue: The hotkey event handler worked,
properly passing control to asus-touchpad.sh, but the sh script itself
would hang at the first "xinput" command.

Title:
  Touchpad Hotkey not working on Asus V6

Status in acpi-support:
  Confirmed
Status in “acpid” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: acpid

  The Hotkey for dis/enabling the touchpad isn't working for me.

  I tried to track the Problem down, but without luck.

  While pressing the key, acpi_listen says:

  hotkey ATKD 0000006b 00000000

  This is the correct entry in /etc/acpi/events/asus-touchpad.

  I've tried to run /etc/acpi/asus-touchpad.sh manually, but all I got
  was:

  nordlicht at Demian:/etc/acpi$ ./asus-touchpad.sh 
  Couldn't find a filedescriptor that points to the terminal.

  nordlicht at Demian:/etc/acpi$ sudo ./asus-touchpad.sh 
  awk: line 1: regular expression compile failed (missing '(')
  :0)
  No protocol specified
  Unable to connect to X server

  After changing #!/bin/sh to #!/bin/bash in /etc/acpi/asus-touchpad.sh I am able to run the Script manually (it works) but the hotkey is still useless.
