Suspend/resume workaround

I managed to get suspend/resume working by disabling Bluetooth.

which way?

How did you disable bluetooth? Did you try unloading the bluetooth kernel module in the sleep script and loading it again on resume? Or did you use a hardware switch or maybe soft disabling the device in /sys/ /proc/ or something? --Low 17:08, 13 January 2009 (CET)

Active Protection System

First: I hope, my english isn't to bad.

I managed to get the HDAPS working under Ubuntu 8.10, but I didn't gain any experience, if the system runs stable. So Test the following at your own risk.

It would be nice, if somebody could verify my mini tutorial. Ok, let's go.

  • Add the jaunty repository to your /etc/apt/sources.list (main and restricted) and run sudo apt-get update.
  • Install the 2.6.28 kernel: linux-image, linux-restricted-modules, linux-headers, linux-headers-*-generic. Thereby you must update linux-firmware, libc6-dev and libc6.
  • Comment the jaunty repository out and run sudo apt-get update. Then install module-assistant.
  • Search the modules thinkpad_ec.ko and hdaps.ko and rename them (of the new installed kernel).
  • Get the Debian packages tp-smapi-source and hdapsd out of the experimental tree.
  • Build and install tp-smapi by (as I did it, only build-essential get installed)
sudo module-assistant prepare tp-smapi
sudo module-assistant auto-install tp-smapi
  • Create /etc/modprobe.conf and add the following lines:
options thinkpad_ec force_io=1
options hdaps invert=1

The issue for the first line is describe in the tp-smapi doc. I checked the output of hdaps by hdaps-gl (part of hdaps-utils). To get an proper output, I needed to add this parameter (see tp-smapi doc too). 

echo 'KERNEL=="event[0-9]*", ATTRS{phys}=="hdaps/input1",ATTRS{modalias}=="input:b0019v1014p5054e4801-*",SYMLINK+="input/hdaps/accelerometer-event"' \
 > /etc/udev/rules.d/51-hdaps.rules
  • At last, install the hdapsd, you downloaded.
  • Have Fun!
