Comment 2 for bug 1730532

In order to test my touch screen to see if it is some-how registering two clicks instead of one, I used xev. I tapped on the xev window, and as sown below, only one tap (press and release) was recorded.

    $ xev -event button

    Outer window is 0x2e00001, inner window is 0x2e00002

    ButtonPress event, serial 25, synthetic NO, window 0x2e00001,
        root 0x211, subw 0x0, time 7842931, (130,118), root:(327,304),
        state 0x100, button 1, same_screen YES

    ButtonRelease event, serial 25, synthetic NO, window 0x2e00001,
        root 0x211, subw 0x0, time 7843049, (130,118), root:(327,304),
        state 0x100, button 1, same_screen YES

I could not test taps on the Ubuntu Dock in using xev.

If someone could suggest how I can monitor events generated by the dock, I will run the test and post the output?
