I have 10.6.3 installed on a Acer Aspire 5610z with 95%+ functionality. As far as I know, the trackpad is a Synaptics Trackpad (but I could be wrong here). The track pad works fine for basic functions, however 2 finger scroll is very "jerky" and not too responsive (and the other advanced functions don't seem to work well either). In my system preferences, I have both the Apple Trackpad preferences icon (next to the Mouse icon in the 'Hardware' section of System Preferences) and I also have the VooDoo PS2 Preferences icon in the 'Other' section at the bottom of the System Preferences window.
The VooDoo preferences has a whole lot of different parameters to change, but I have no real clue what does what and trial and error has not been producing any significant results. So my basic question is, is there a guide that tells you how to use the VooDoo parameters, together with the Apple trackpad parameters, so that I can set up the advanced track pad functions?
