Tweak BB -Disabling Screen blanking although may resolve my issue of not having the N9 autolock, it does so at the cost of leaving the display on the whole time.

I remember setting my display timeout to 1min so I multiplied the above value in the first post of 1345707064 by 3 in order that the display timeouts in 1 min and the phone will thus only autolock after 3 mins which is perfect for me. Will let you know if it works.
