 Thinkpad T60 volume buttons in 9.04 and 9.10
Hi all.
I've a thinkpad T60 and 9.10 installed. I did some search on the forums and found the workaround with tpb package to fix thinkpad volume buttons issue.
My problems with that fix are:
-tbp package depens on xosd (or whatever like that, NOT Notify-OSD) so the result is not the best...
-tpb package is not neccessary at all, because thinkpad_acpi module can take care about volume buttons as well, you just have to enable the hotkey mask! http://www.thinkwiki.org/wiki/Thinkpad-acpi

So my workaround on T60 (in terminal):
9.04 jaunty:
Code:

sudo echo enable,0x00ffffff > /proc/acpi/ibm/hotkey

9.10 karmic: (using sysfs):
Code:

sudo cp /sys/devices/platform/thinkpad_acpi/hotkey_all_mask /sys/devices/platform/thinkpad_acpi/hotkey_mask

Please confirm if the solution works on other thikpad models.

PS.: Just noticed, that after a few suspend/resume cycles or reboot, you have to update the keymask again. (somehow something overwrites it, couldn't figure it out yet.)
