    Kubuntu 16.10 replaces the old screen shot tool KSnapshot with Spectacle but does not change the keyboard setting accordingly. Under System Settings -> Shortcuts -> Custom Shortcuts the folder "Screenshots" must be developed to show an entry "Start Screenshot Tool". The trigger for this entry must be set to be the print screen key. A dialog will prompt warning that the key is already assigned; it is assigned to KSnapshot; therefore ignore the warning.

  2. This seems to have changed again in Plasma 5.20+ as per recent Fedora upgrades. The print screen key is assigned to dbus StartAgent command of Spectacle, which actually starts Spectacle in the background and shows nothing (basically useless). For a fix today you may need to reset the shortcut as per above but I think Spectacle has changed its behavior (v20.12.2 here).

  3. In KDE Neon, Go to Settings > Shortcuts > Global Shortcuts > KDE Daemon. You'll find two options named Take Full Screen Screenshot and Take Rectangular Region Screenshot, press the key area and assign to it the input key you please. This way you'll take a screenshot without having to open Spectacle each and every time which is kind of annoying.

  4. In my case, there even was no "Screenshots" folder under "Custom shortcuts"!

    Fortunately, those shortcuts can be added from scratch as commands (edit -> new -> global shortcut -> command/url). For example, spectacle -r -b is to capture rectangular area, without showing KDE Spectacle window.

    Type spectacle --help in console to see all available options.
