Isn't this bug an extension of bug #357673? The thinkpad_acpi kernel maintainer has said he's opposed to forwarding these keypresses to userspace, on the grounds that the kernel behavior is already consistent with how these keys operate under Windows - controlling the hardware/BIOS mixer instead of acting on the OS mixer.
In fact, I see Henrique has commented in the upstream bug, apparently to exactly this effect. -- Mute button not properly working on current Lenovo Thinkpads x200/x200s , t400/t500, X300/X301, & W series https://bugs.launchpad.net/bugs/281732 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
