Comment 143 for bug 308191

I have reverted back to using two-finger emulation, because I just can't get used to two-finger scrolling with the fingers apart, that is really unconvenient (same thing as with Windows and official Synaptics driver).

synclient -m 100 reads as follows :
two fingers apart : 2 fingers registered, width 5
two fingers joining : 1 finger registered, width 15

So I understand why two-finger scrolling won't work with the fingers joining : they register as one finger only.

I just don't feel comfortable with the fingers apart, so I am going back to my emulation script.
