The line in dmesg interests me: [ 15.882471] thinkpad_acpi: asked for hotkey mask 0x078dffff, but firmware forced it to 0x008dffff
what does it do if you `echo 0x078dffff > /sys/devices/platform/thinkpad_acpi/hotkey_mask` "0x0700-0000" is not really documented in the thinkpad_acpi source code, so I wonder what these bits are and if they makes any changes to the behaviour. or `echo 0x00fdffff > /sys/devices/platform/thinkpad_acpi/hotkey_mask` This flips the hotkey bit mask for mute/vol-up/vol-down keys. I think it will also be great if one with the hardware can post the content of /sys/devices/platform/thinkpad_acpi/hotkey*. There are several files, but good for debugging reference. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/595896 Title: Thinkpad SL510 Mute button not working -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
