I'm using touchegg and synaptics, and I'm trying to configure synaptics 3-finger gesture sensitivity. Currently, 3-finger dragging is being triggered by accident, and I think if I could configure a minimum finger distance for triggering events it would solve the matter.
I say this because I've realized that 3-finger gestures are being triggered no matter how appart the touch points are.
I've already enabled PalmDetect, and tweaked a bit, which helped a lot avoiding random 2-finger scrolling, but didn't help for 3-finger.
EDIT
At the moment, as a way out, I had changed my 3-finger gestures to 4-finger ones so it gets harder to generate random effects.
Look at the
HorizHysteresis
andVertHysteresis
of synclient. Here's what they do according toman synaptics
