I also noticed this bug on a thinkpad T43 in Karmic.

[Jeff Fortin Tam (kiddo)]

I should mention that the volume through the thinkpad volume keys now behaves independently from the volume applet. And if you put both at the maximum, it will be way too loud and the sound will distort.

[Luis Carlos Cobo (luiscarlos)]

Same behavior with T60 on Karmic. And the volume setting is indeed independent from the software mixer, as Jean-Francois notes, which is a bit annoying.

[Richard Appleby (disposable01)]

Some problem seen here on my Thinkpad T60p with the latest Karmic updates.

[Gustav Svensson (gustav-svensson)]

Same with X41.

[Bart Rose (jbrose3)]

Same on R52. Also, brightness OSD fails to be displayed.

[Neo (vohnik-gmail)]

Same on T42, OSD (volume, brightness, thinklight, ...) is not working.

[Daniel Agar (dagar)]

x60s no volume control OSD, however the volume keys do work and the brightness keys are working properly with OSD.

[Jodie Cunningham (jodie-cunningham)]

x60s, upgraded all the way from 8.04 LTS to 9.10 last night, no OSD for volume, but volume buttons do work if you hold them down. Brightness keys are working with OSD.

[Xzan (shgun-xzan)]

I have a Thinkpad R50e and i had the same problem as you since Ubuntu 9.04.
I though that Ubuntu 9.10 would fix it but it didn't so i search to fix it myself and i find something
I got on the thinkpad-acpi website and they say that we should look in the documentation "thinkpad_acpi.txt" which i find on this website : http://www.mjmwired.net/kernel/Documentation/laptops/thinkpad-acpi.txt

On line 219, it says how to enable all hotkey.

Here's how i did it :

$ sudo -s
# echo 0xffffffff > /proc/acpi/ibm/hotkey

And it works :) Now, i got the OSD for volume and brightness hotkey :)

Hope this is gonna help you ;)

Hello --

Xzan's post does temporarily fix the hotkeys for my Thinkpad T43 (thanks for the post!).

I have had hotkey problems since 9.04 as well, but had previously fixed them by rolling back to an older version of the hotkey-setup driver.

sudo dpkg -i ~/hotkey-setup_0.1-23ubuntu7_i386.deb

I'd prefer to figure out how to make Xzan's fix persist through a reboot ...

Please pardon my ignorance if this is a trivial task.

[Xzan (shgun-xzan)]

I have noticed as well that my fix wasn't persistent. So i search the web once again and found a work around :

1) Edit /etc/rc.local

$ sudo gedit /etc/rc.local

2) add before return 0 :

#Fix for the hotkey, added the 10/31/2009
echo 0xffffffff > /proc/acpi/ibm/hotkey

3) create and edit a script for the resume :

$ sudo touch /etc/acpi/resume.d/91-tp-hotkey-fix.sh
$ sudo gedit /etc/acpi/resume.d/91-tp-hotkey-fix.sh

4) add the following in the script :

#!/bin/bash
# fix thinkpad-hotkeys

echo 0xffffffff > /proc/acpi/ibm/hotkey

5) close and save.

I have rebooted and my hotkeys were still making the OSD appears.

(Source : "Configuring ACPI" part from http://www.thinkwiki.org/wiki/Sample_fn-F7_script )

[Richard Appleby (disposable01)]

After step 5 you'll also need to do:

$ sudo chmod 755 /etc/acpi/resume.d/91-tp-hotkey-fix.sh

Otherwise this workaround works fine on my T60p.

[James Burrell (jaburr)]

Thanks for the help folks. With Xzan's additional steps (& SixedUp's tweak), I think the hotkeys are working normally now on my T43.

Will try on my T60p when I upgrade it, but for now I think we have a band-aid.

A little puzzling as to why this OSD functionality for Thinkpads has been shaky for the past two releases.

JB

[Dimitris Kogias (dimitris-k)]

On a X60 at least, Xzan's fix has an undesirable side-effect: When I press the Thinkpad volume up/down keys, OSD is now displayed. However, the volume up/down keys now control both the Thinkpad hardware mixer and the main mixer. You can see that by watching the mixer/volume applet's reported volume (dB / %) as you are pressing the up/down keys.

In effect, this undoes the "fix" from #355300. For even more gory details, see the upstream bug at https://bugzilla.gnome.org/show_bug.cgi?id=524425.

After reading that I'm sticking with tpb :-(

[Andre (ajx)]

The same on Thinkpad X41. Buttons do work, but no OSD for Volume and Brightness though. :(
It was working properly on Hardy and Intrepid. Never had Jaunty on this notebook.

[Mark (mark-wege)]

I have the same problem on a TP R50e.

[EricDHH (ericdhh)]

On the T42 the fix did not work, setting the mask to /proc or /sys from within /etc/rc.local did not work. I have to set the mask after login by hand, then the osd works well.
Using /proc is deprecated, try this instead

echo 0x00ffffff > /sys/devices/platform/thinkpad_acpi/hotkey_mask

But in /etc/rc.local nothing happens........
