@Herton That's right. I forgot it actually sends a acpi event. Which thinkpad-acpi is catches then sending the KEY_UNKNOWN keycode. The link you pointed out to the patch whould just label the acpi event in thinkpad-acpi but still would not help solving the whole problem.
Getting a generic key to map to is the first step to solving the issue. Though there does seem to be little interest from the community to create it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751471 Title: [Lenovo T410] Microphone mute key does not fuction -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
