  Hmm, KDE accepts both scrolling settings being enabled at the same time.
I don't know if turning two finger scrolling would make any difference.
You can get/set current scrolling state by running synclient or xinput, though:

   $ synclient | grep Scroll # get current scrolling options
   $ synclient VertEdgeScroll=1 # enable vertical edge scrolling
   $ synclient VertTwoFingerScroll=1 # enable vertical two finger scrolling

  If you don't have the time to rebuild the kernel with FSP_DEBUG, tweaking
the RightEdge parameter probably helps but you'll have to guess the value
since you don't have the accurate geometric information(which probably isn't
correct enough in current driver):

   $ synclient | grep RightEdge # get the right edge boundary
   $ synclient RightEdge=?? # reduce the value and see if right edge scrolling can be detected
