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? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1730532 Title: Tapping on an icon in the dock launches two instances of the application To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1730532/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
