On a freshly rebooted system, I see the following: # cat /sys/devices/platform/thinkpad_acpi/hotkey_all_mask 0x00ffffff # cat /sys/devices/platform/thinkpad_acpi/hotkey_mask 0x008c7fff # cat /sys/devices/platform/thinkpad_acpi/hotkey_recommended_mask 0x008c7fff I just found a similar bug: https://bugzilla.opensuse.org/show_bug.cgi?id=849309 It was resolved as WONTFIX based on the assumption that this behaviour depends on the user's configuration. If that's actually the case, I'd prefer it to be slightly more user-friendly.
