I have a mic mute button on my Lenovo Thinkpad T420 , but it doesn't work.
So I tried
xev command to monitor press event, and that key wasn't captured.
Is there anyway to fix it , like add raw key code ?
OS & Laptop
Ubuntu 12.04 , also hope it works on Arch Linux , but doesn't matter much ;-P
Kernel patch for Arch Linux
It's a little tricky , but with the kernel patch and acpid script , it works now.
The rest I need is a notify daemon like the one for output mute , but it doesn't matter much now.
