Yes - the above post will enable two finger scrolling to work for the aspire one. I did that to mine a couple weeks ago.
Here's how to do it: Follow all of the instructions ranova gives at the following url:
http://forum.insanelymac.com/index.php?showtopic=88811NOTE: After step four, your trackpad may become a bit shakey so having an external mouse will make finishing the remaining steps much easier. I did it without an external mouse but it requires just a bit of patience to operate that "caffinated mouse"!
Once you get to step 6 it should be controllable. But don't forget to do step 9 or your mouse will act up again after you restart.
Note: Make sure you have this command written down or saved somewhere:
"sudo killall -9 FFScrollDaemon
sudo /usr/local/bin/FFScrollDaemon"
If you update certain kexts your mouse might get shakey again and you will need to re-enter those commands in the console & reboot to fix it again.
It works pretty good!
With my current settings its not a two finger scrolling but rather:
finger tip = normal mouse
pad of finger flat = scrolling
Here's my current FFscroll Settings (pretty much default):
Vertical Scrolling Sensitivity and Speed settings: low
Samples to log: 8
Sample Threshold:60
Sample Decline Threshold:10
If anyone comes up with some good settings for FFscroll for the Aspire One please post them.
