No, it says so. But it also says that it depends on which version of the thinkpad-acpi we've got in ZW6, and I don't know that for sure.

What does lsmod tell you? And can you find the documentation text-file referenced above?

I have no idea what it means, though. . . (I just swtiched from Windows).

I found the documentation in the kernel-source. Apparently thinkpad_acpi have moved from procfs to sysfs. This apparently means that there are no longer a bunch of acpi-files (correct me if I am wrong). So, I believe the configuration are now located in /sys/devices/platform/thinkpad_acpi.
The question is whether these files should be edited manually or via some software.

From the txt file:

Code:

Thinkpad-acpi Hot Key event map (version 0x4101):

ACPI   Scan
event   code   Key      Notes

0x1001   0x00   FN+F1      -
0x1002   0x01   FN+F2      IBM: battery (rare)
            Lenovo: Screen lock

0x1003   0x02   FN+F3      Many IBM models always report
            this hot key, even with hot keys
            disabled or with Fn+F3 masked
            off
            IBM: screen lock
            Lenovo: battery

0x1004   0x03   FN+F4      Sleep button (ACPI sleep button
            semantics, i.e. sleep-to-RAM).
            It is always generate some kind
            of event, either the hot key
            event or a ACPI sleep button
            event. The firmware may
            refuse to generate further FN+F4
            key presses until a S3 or S4 ACPI
            sleep cycle is performed or some
            time passes.

0x1005   0x04   FN+F5      Radio.  Enables/disables
            the internal Bluetooth hardware
            and W-WAN card if left in control
            of the firmware.  Does not affect
            the WLAN card.
            Should be used to turn on/off all
            radios (Bluetooth+W-WAN+WLAN),
            really.

0x1006   0x05   FN+F6      -

0x1007   0x06   FN+F7      Video output cycle.
            Do you feel lucky today?

0x1008   0x07   FN+F8      IBM: toggle screen expand
            Lenovo: configure UltraNav

0x1009   0x08   FN+F9      -
   ..   ..      ..
0x100B   0x0A   FN+F11      -

0x100C   0x0B   FN+F12      Sleep to disk.  You are always
            supposed to handle it yourself,
            either through the ACPI event,
            or through a hotkey event.
            The firmware may refuse to
            generate further FN+F4 key
            press events until a S3 or S4
            ACPI sleep cycle is performed,
            or some time passes.

0x100D   0x0C   FN+BACKSPACE   -
0x100E   0x0D   FN+INSERT   -
0x100F   0x0E   FN+DELETE   -

0x1010   0x0F   FN+HOME      Brightness up.  This key is
            always handled by the firmware
            in IBM ThinkPads, even when
            unmasked.  Just leave it alone.
            For Lenovo ThinkPads with a new
            BIOS, it has to be handled either
            by the ACPI OSI, or by userspace.
0x1011   0x10   FN+END      Brightness down.  See brightness
            up for details.

0x1012   0x11   FN+PGUP      ThinkLight toggle.  This key is
            always handled by the firmware,
            even when unmasked.

0x1013   0x12   FN+PGDOWN   -

0x1014   0x13   FN+SPACE   Zoom key

0x1015   0x14   VOLUME UP   Internal mixer volume up. This
            key is always handled by the
            firmware, even when unmasked.
            NOTE: Lenovo seems to be changing
            this.
0x1016   0x15   VOLUME DOWN   Internal mixer volume up. This
            key is always handled by the
            firmware, even when unmasked.
            NOTE: Lenovo seems to be changing
            this.
0x1017   0x16   MUTE      Mute internal mixer. This
            key is always handled by the
            firmware, even when unmasked.

0x1018   0x17   THINKPAD   ThinkPad/Access IBM/Lenovo key

0x1019   0x18   unknown
..   ..   ..
0x1020   0x1F   unknown

As far as I can tell alle the above should be enabled if hotkey_enable is 1 (which it is in my case. No love though).

Also:

Code:

hotkey_report_mode set to 1 makes the driver export through the procfs
ACPI event interface all hot key presses (which are *also* sent to the
input layer).  This is a legacy compatibility behaviour, and it is also
the default mode of operation for the driver.

I think that means that the ACPI event should be used, but really they are not. (hotkey_report_mode set to 1).

This is really confusing

First try removing and re-adding the acpi module:

Code:

# modprobe -r thinkpad_acpi
# modprobe thinkpad_acpi

and see if you get any messages. Also run

Code:

# modprobe -c thinkpad_acpi

to dump configuration file location(s).

Latest version (beta) is 0.22: http://sourceforge.net/project/showfile ... _id=117042

SoleSoul · **Posted:** Tue Mar 31, 2009 9:45 pm

This is how to enable the volume keys in T61.

Please help me create a useful page for a better world $:-\$

Hello,
First of all thanks for the help so far. I somehow broke my Zenwalk distro and I just got it back together. However the problem regarding thinkpad_acpi persists.

I tried but it did not seem to do a difference. There are no messages.

I would need to update the kernel manually to install the latest version, right?
I could get the kernel-source to check which version is included.

Thanks,
Rasmus

toothandnail · **Posted:** Sat May 02, 2009 3:12 am

You can check the version of thinkpad_acpi in the kernel this way:

Code:

dmesg | grep thinkpad

On my Zenwalk 6.0 installation (kernel 2.6.28.7) that reports:

Code:

Thinkpad ACPI Extras v0.21

rasmus · **Posted:** Sat May 02, 2009 9:05 am

Thanks Paul,
I have the same version:

Code:

thinkpad_acpi: ThinkPad ACPI Extras v0.21
thinkpad_acpi: http://ibm-acpi.sf.net/
thinkpad_acpi: ThinkPad BIOS 7BETD7WW (2.18 ), EC 7BHT40WW-1.13
thinkpad_acpi: Lenovo ThinkPad X60, model 1706M8U
thinkpad_acpi: ACPI backlight control delay disabled
thinkpad_acpi: radio switch found; radios are enabled
thinkpad_acpi: This ThinkPad has standard ACPI backlight brightness control, supported by the ACPI video driver
thinkpad_acpi: Disabling thinkpad-acpi brightness events by default...
thinkpad_acpi: Standard ACPI backlight interface available, not loading native one.

The strange thing is volume buttons works out of the box but none of the Fn-Fx-combinations works...

Running a bit late ... and it seems there hasn't been much going on since May. Just installed Zenwalk 6.2 on my ThinkPad T42. About 37 Gb disk (total) and 1,5 Gb RAM. I simply couldn't bear using my old PII 400 MHz machine anymore - it seems Zenwalk 6.2 is too demanding.

Any help on ThinkPad configuration is very appreciated. For one, the keyboard is worn out, but I have a Logitech diNovo Edge Keyboard (Bluetooth) that I'd like to use, if possible.

Best regards,
Claus
