When I close a konsole with the window manager, konsole pops up a dialog Confirm Close - Konsole There is a check box "Do not ask again" but if I select that, then select the [Close Window] buttom, konsole does not remember the option and asks again the next time. konsole --version Qt: 5.5.1 KDE Frameworks: 5.18.0 Konsole: 15.12.3
You're on a somewhat old version What does "cat ~/.config/konsolerc " show? Should be something like: [Notification Messages] CloseAllEmptyTabs=true
I added that section to ~/.config/konsolerc and konsole no longer pops up a confirmation. I'm on Ubuntu 16.04 LTS (Xubuntu, really) and 15.12.3 is what I got from the default `sudo apt install konsole`
This seems to work correctly in version 16.12.2.
closing as it is fixed in later versions
