Created attachment 136914 [details] screenshot STEPS TO REPRODUCE 1. enable Touchpad applet in system tray 2. assign a keyboard shortcut in the setiings of Touchpad applet 3. trigger the Touchpad applet by pressing its keyboard shortcut OBSERVED RESULT state of the touchpad changes as expected and "Touchpad" popup immediately opens. See the attached screenshot please. This pointless popup does not open when I trigger Touchpad applet with mouse or touchscreen. EXPECTED RESULT Touchpad applet should work in the same way regardless how it is triggered (mouse, touchscreen, keyboard shorctut). SOFTWARE/OS VERSIONS Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.21.80 KDE Frameworks Version: 5.81.0 Qt Version: 5.15.2 Graphics Platform: X11

Git commit 3b4026641454c02ad3030c8cd2134a672995ffa9 by Nate Graham. Committed on 18/05/2021 at 18:15. Pushed by ngraham into branch 'master'. Delete the Touchpad applet Ths only thing this applet can do is disable or re-enable your touchpad. If you have no touchpad, it is pointless. If you have only a touchpad and no mouse, then the only thing it can do is give you a way to brick your laptop until you find a mouse you can use to re-enable the touchpad. The only conceivable non-catastrophic usage of this applet is to manually disable a laptop's touchpad when a mouse is plugged in. This is an extremely niche use case that can already be accomplished by using the "Toggle Touchpad" keyboard shortcut which is exported by the KCM, and would be better served by a setting in the touchpad KCM itself to automatically disable the touchpad when a mouse is plugged in and re-enable it when unplugged, should such a feature be deemed useful. I have my doubts, as Libinput has gotten very good at ignoring false input these days, so I think there is no longer much of a use case for disabling a touchpad at all. Overall, this applet is not worth the bugs and degradation of the user experience that it can cause. It is too dangerous to exist. Let's delete it.
