After the latest updates, enabling touchpad on/off key (fn-f8) is now working. There are some annoying gdm random restarts without a trace in the logs. I suspect it’s the nvidia proprietary driver and I hope it will be fixed soon.
Here is a better approach to enable the Active Protection System in your ThinkPad:
# Install HDAPS - IBM Active Protection System Linux Driver sudo cp /etc/modules /etc/modules_backup sudo aptitude install tp-smapi-source sudo module-assistant prepare tp-smapi sudo module-assistant auto-install tp-smapi sudo modprobe tp-smapi sudo aptitude install hdapsd echo 'tp-smapi' | sudo tee -a /etc/modules
