Comment 4 for bug 773138

Geistest seems to capture correct gestures, containing up to two buttons (more probably not supported by the hardware):

Gesture id 454 type 0 finished
 attr "device id" = 10
 attr "timestamp" = 21330897

 attr "touch 0 id" = 2.000000
 attr "touch 0 x" = 807.924805
 attr "touch 0 y" = 328.580231
 attr "touch 1 id" = 3.000000
 attr "touch 1 x" = 676.061279
 attr "touch 1 y" = 458.100739

Why are those not giving any effect in the desktop or any programs?
