Hello,

since I'm running Lubuntu 12.10 on a Samsung N145 netbook, I'm having a problem using two-finger tap and scroll on the touchpad. Both gestures work, but often the two-finger tap (which I'm using as the middle mouse button) causes a two-finger scroll. This is extremely annoying when browsing web pages and using the two-finger tap to open a link in a new tap. The browser often randomly scrolls away from the link instead of opening it.

Before Lubuntu 12.10 I was using Ubuntu 11.10, and I still have Mint 9 LXDE on a second partition. Both do not show this behaviour.

I guess I can somehow fine-tune this with synclient. I already found out that I have to create an xorg.conf file to make my synclient settings persistent (I did not find a GUI tool for touchpad configuration in the system settings). Can someone point me to the right option or combination of options to make the touchpad's two-finger tap more reliable?

Here are my current settings:

Code:
xxx@crossfire:~$ synclient -l
