I just got a lightly used Lenovo ThinkPad X220 for only $200 (it was going to be scrapped despite being in perfect condition) and I love it so far, but I was curious about gesture support in Linux. I have installed Xubuntu on my laptop, and out of the box the only gesture I can find is two finger scrolling and two finger tapping. What I'm really looking for is is swipe gesture support, particularly in a browser (e.g. two finger swipe left to go back one page, etc.). I know my laptop has a Synaptics trackpad, but I don't know what it supports as far as gestures. I found a program called Touchegg that can create actions for gestures but I'm having trouble getting it to work.
