Hi All,
I hope you are well.
I got this problem after recent update where I cannot use Yakuake with F12 key.
So when I checked in Yakuake Keyboard Shortcuts - Open/Retract Yakuake was blank, I tried to set it back to F12 but it throws a pop up "Conflict with Registered Global Shortcut. The shortcut 'xx' conflicts with the foloing key combination:" but there is nothing afterwards.
Even if I try to change the binding to Ctrl-Shift-F12 it still complaints with the same popup.
I am on LXDE but I don't see any shortcut for F12 that could interfere.
Best regards

I doubt that Yakuake will run without errors on desktop environments other than KDE Plasma. Here is also no support for other GUIs. You should consider switching to KDE Plasma if you want to use Yakuake and other KDE software.
