The print screen key does not open the screen shot tool in Kubuntu 16.10.

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.

    It seems that this is only an issue when updating from Kubuntu 16.04 LTS. – Stéphane Tréboux Oct 15 '16 at 15:04

    With this solution only one instance of spectacle is allowed when pressing "print screen". Is there a way to make it open a new instance for each button press? – GuySoft Dec 11 '16 at 10:34

    `Start screenshot tool` is assigned to the key, however still can't call Spectacle app by `Print` key only manually. Any other ideas? – Aleksey Kontsevich Jul 24 '17 at 02:11
  • What should be the action for this entry? – HighCommander4 Jan 20 '18 at 20:20
  • I don't have access to my computer now but as far as I can remember the action "Start Screenshot Tool" was already pre-configured when Spectacle is installed. The only missing configuration is the trigger setting (the print screen key). – Stéphane Tréboux Jan 21 '18 at 02:53
  • I just came home and checked the action "Start Screenshot Tool". Remote application is "org.kde.Spectacle", remote object is "/", function is "StartAgent", arguments is "" (empty). Alternatively the function "FullScreen" will directly take a screenshot of your full screen and the function "ActiveWindow" will directly take a screenshot of the active window. As I wrote before I never had to input any of this myself, this comes already configured with Spectacle, only the trigger setting (the print screen key) was missing in my case. – Stéphane Tréboux Jan 21 '18 at 08:17
  • same issue for bionic 18.04 – user2997418 Jul 20 '18 at 09:06
  • Simply installing `spectacle` did it for me, some reasonable shortcuts were automatically added to their own category in the "global" shortcuts. – Fabian Röling Jun 30 '20 at 16:33

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).

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.

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.
