Public bug reported:

Binary package hint: utouch

The Synaptics touchpad in my ThinkPad T510 should be able to recognize
four simultaneous touches according to the output of "geistest":

Device 10 added
    attr "device name" = "SynPS/2 Synaptics TouchPad"
    attr "device id" = 10
    attr "direct touch" = false
    attr "independent touch" = false
    attr "device touches" = 4
    ...

However, when doing three or four finger taps, I only get lines like

attr "gesture name" = "Tap,touch=2"

On the other hand, three finger taps simulate a double click, so I'm not
sure if that's a limitation by uTouch or if the hardware reports wrong
capabilities.
