[Bug 357673] Re: No notification when sliding audio volume, muting volume on ThinkPad X23, X24, X31, X32, X41, X60, T22, T40, T42, T60, R50e, R51, R52

@Bruno (and Uwe)

I do NOT agree with you, as volume control DO NOT cooperate with the KDE/Gnome volume control applet (and neither with the OSD indicator) on Lucid with a 2.6.33 kernel (found in ubuntu mainline kernels) - BTW same for .34 and .35.
NEITHER does it work in Maverick beta 1+2+3, even if the keyboard bottoms is able to adjust the volume here too (like Uwe describes). I've done extensive tests on more of the reported boxes (from the bug-headline), and every test on new installations - apart from the kernel of course.

The only thing that makes this (and on some boxes the also the broken brightness control and OSD) work, is adding:
cp /sys/devices/platform/thinkpad_acpi/hotkey_all_mask /sys/devices/platform/thinkpad_acpi/hotkey_mask
to /etc/rc.local
And even though a big WARNING has been given by someone (was it Henrique), this just works every time and even in Karmic.

>From what I understand from comment #112, only an alsa mixer was put in
place in .33 kernel, which does not mean that KDE/Gnome uses this mixer
- at least it seem that no buntu release does yet.

So of course it would be pretty great if it could be fixed before
Maverick is released.
