Fixing HDAPS (harddrisk protection) on Thinkpad Edge 15

[Redsandro]

I am trying to use my accelerometer as joystick just so I know it's working, but I can't figure out how.

To my surprise, Ubuntu doesn't seem to have a nice GTK joystick testing dialog. There used to be hdaps-gl out there for testing, but this was for very old models and is only released for Ubuntu 8.04 afaik. So I tried installing neverball for that purpose. It doesn't have options for joystick selection, but apparently it works out of the box with a Thinkpad T61.

sudo aptitude install tp-smapi-dkms
sudo modprobe tp_smapi
sudo modprobe hdaps

dmesg:

[  720.093604] thinkpad_ec: thinkpad_ec 0.40 loaded.
[  720.095348] tp_smapi 0.40 loading...

[  842.861696] input: ThinkPad HDAPS accelerometer data as /devices/virtual/input/input11
[  842.861883] hdaps: driver successfully loaded.

lsmod:

Module                  Size  Used by
hdaps                  10772  0 
tp_smapi               26194  0 
thinkpad_ec             5842  2 hdaps,tp_smapi
(..)

I've also tried to use jstest with
/dev/input/js[0|1]
and
/devices/virtual/input/input10/[many things]
But the former gives static 0 for both axes and the second gives error messages (you're probably not supposed to use it like this).

Any ideas?

*Well-deserved-bump*

Anyone? Lenovo is a popular brand, and above all, the Thinkpad Edge is Ubuntu Certified, so I am guessing a lot of people have this laptop.

And since it is certified, one would guess stuff like this should work.

Apparently, there's also a special image of Ubuntu 10.10 available for this laptop but I cannot find it on the entire internet.

I'm trying to figure out how to use my accelerometer as well. It seems nobody on here knows how to do it.

I've got exactly the same problem on my Thinkpad Edge 11. The driver loads fine, but when testing with jstest I just get a static 0 on both axes, and neverball doesn't work.
