Just installed Ubuntu 12.10 on a Lenovo 3000 n1000. Fairly often, approximately once every ten minutes, the pointer will lock. As in, whatever state it's in: clicked, right clicked, scrolling, selecting, etc, it stays in and won't change.
My temporary solution has been to disable and re-enable the trackpad using Touchpad Indicator through the terminal, but this is rather burdensome.
Very much appreciate any pointers or aid. Can post additional information if needed.
