SUMMARY App keyboard shortcut F12 worked initially upon installing and starting Yakuake, but stopped working afterwards. STEPS TO REPRODUCE 1. Install and start Yakuake; press F12 to see if it works 2. Restart the computer 3. Press F12 to see if it still works OBSERVED RESULT Next day I couldn't get Yakuake working when I pressed F12. All attempts at changing keyboard shortcut or adding custom keyboard shortcut didn't help. EXPECTED RESULT Pressing F12 should always start Yakuake. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 20.10 KDE Plasma Version: 5.19.5 KDE Frameworks Version: 5.74.0 Qt Version: 5.14.2 ADDITIONAL INFORMATION I've managed to find this workaround: removing Yakuake app keyboard shortcut from System Settings:Workspace:Shortcuts:Global Shortcuts, and instead adding it to Custom Shortcuts.
Sounds like this could be the same bug I just reported here: https://bugs.kde.org/show_bug.cgi?id=506605 Though my description was very different, as the shortcut did work (though I had already a long time ago changed it from F12) right uptil I went to change the keyboard shortcut - and I only managed to wipe the custom shortcut, but not configure a new binding, or even change it from "custom" to "default" (F12) again. So I can't open it anymore - sucks badly. I also don't have KDE desktop even installed, so I can't access those settings the way you mention, as I would need to be running KDE. I'm currently using XFCE, and likely soon moving back to plain WM (which will be a tiling one).
