Hej !

The problem with the hdaps_ec module not loaded at boot, was only that in /etc/modules i had the following line :
hdaps_ec # and some comment here
and the comment made a problem !
Sorry for that.

But now, i encounter athe following issue, already mentioned by others : i have (apparently randomly) sometimes 4 available rotations, and sometimes only 2. Did someone managed to fix this ?

Thanks

Nicolas

Hello,

Great stuff. The tilt detection and automatic rotation work very well !
One small problem, nevertheless : if i load the module manually with modprobe hdaps_ec, this works. But at boot, the module is not loaded automatically, even if i add the line
hdaps_ec
to the file
/etc/modules
How can i fix this (sorry for this newbie question …) ?

thanks

Nicolas

[...] (for example, does tilting it forward make the picture of the laptop tilt forward?). If not, go HERE and follow the troubleshooting section. Hopefully though, everything will work and you can continue [...]

[...] sure you have a working accelerometer that is reading the proper orientation as tested using the hdaps-gl [...]

This won’t work properly for me unless the lines for Virtual Display (see here) are added to /etc/X11/xorg.conf. The unfortunate consequence is that compiz seems to stop working when I do that. Any ideas?

tp_smapi and hdaps_ec are loaded in /etc/modules and did not need recompiling (as per the note). Tilt detection is accurate with hdaps-gl and running autorotate.py yields no errors and prints integers (between 1 and 4) upon rotation of the laptop.

A Big Thanks for sharing your knowledge in such a clear and simple article.

I followed it, and was able to run the IBM Accelorometer successfully.

Thanks again:)

Unless Ubuntu patched the kernel with the diskprotect patch by default, which I don’t think it does, I hope you all know that this only activates the accelerometer and does not actually park the hard disk. With the above procedure, you can only monitor tilt, do not bump your laptop around too much as it will damage the drive.

In order to park the hard disk, you have to patch and recompile the kernel.

I mentioned this because someone linked from thinkwiki to this site and probably presumed that it would protect the hdd.

Read http://www.thinkwiki.org/wiki/HDAPS carefully for directions on patching the kernel and recompiling.
