Trackpad messes up sometimes when I start Ubuntu 11.10, scrolling problems

view full story

http://askubuntu.com – I just installed Ubuntu 11.10 on my Sony VAIO and almost every other time I start it up my trackpad doesn't work. It will move but not the direction I try to move it, it just shakes around and sometimes goes the complete opposite direction. However when I restart the comp once or twice it will work fine. Also I cant get my trackpad to scroll at all. There is a question on here that has addressed that, and I've tried the suggestion made but to no results. Any help would be greatly appreciated. (HowTos)
