http://bugzilla.opensuse.org/show_bug.cgi?id=931543 Bug ID: 931543 Summary: Thinkpad R60/T60 Hotkeys hotkey mask mismatch Classification: openSUSE Product: openSUSE 13.1 Version: Final Hardware: x86-64 OS: openSUSE 13.1 Status: NEW Severity: Normal Priority: P5 - None Component: Other Assignee: bnc-team-screening@forge.provo.novell.com Reporter: ernestopheles@googlemail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- * Reproducible: openSUSE 13.1 x86_64, KDE 4, clean standard set-up, always * Symptom: On R60 and T60 series Thinkpads, volume and brightness changes through hotkeys are not acknowledged by the operating system * Fix: One-line command * Last known to work without a flaw: openSUSE 12.3 On R60 and T60 Thinkpads, volume and brightness hotkeys are not correctly interpreted. The brightness hotkeys work, but the system does not acknowledge the change with its usual pop-up/overlay notifications (KDE4). The volume keys work, too, however there are also no pop-up/overlay notifications and the volume is changed using the acpi subsystem (which can be observed by monitoring /proc/acpi/ibm/volume) while the volume of pulseaudio remains untouched. The following command reveals a mismatch of hotkey masks: # cat /sys/devices/platform/thinkpad_acpi/hotkey_all_mask /sys/devices/platform/thinkpad_acpi/hotkey_mask 0x00ffffff 0x008dffff It can be fixed by executing the following command with root privileges: # cat /sys/devices/platform/thinkpad_acpi/hotkey_all_mask > /sys/devices/platform/thinkpad_acpi/hotkey_mask This single change causes the hotkeys/buttons to work again as expected.
