I just tried MX Linux, and I actually like it a lot, but I'm desperately trying to find a Screenshot tool without any dialog.
I mean, I want to be able to set up a keyboard shortcut like Print or similar and a target folder to save the screenshot file and when I hit the shortcut, the screenshot should be saved automatically in the target folder without any popup, window, message,... whatsoever.

Could anybody of you by any chance recommend such a tool, please?

That tool should produce files called something like 'screenshot-[date-time].jpg' (or ....png)

Spectacle (KDE app) can be configured to do exactly what you're saying, although you may drag in lots of KDE dependencies to use it.

EDIT: Nevermind, it still requires input.

Input would be ok, if it is required prior to perform several screenshots at once.
So, for example, if you hit the shortcut 10 times in a short period of time,
the resulting 10 files should be saved automatically into a predefined folder,
without having to set them up one by one.

EDIT:
Meanwhile, I installed mate-screenshot, because that one gets at least a bit closer to what I'm after.
But still there's this annoying window, which has to be closed manually by pushing the ENTER key,
which makes it impossible to quickly make several screenshots at once.

madmax - you destroy the bodhi forums with your many questions due to your breaking your system and then do not foloow people's suggestions. i hate to say it but do not bring your trash here to the antix/mxfoums.

scrot works for me.
Look in Mx hot keys and sub scrot for like what ever you don't use. Or make scrot -s work in your menu.



Shift Print Screen key combo works on some. Not sure of mx

but reading my keys file

which brings up the dialog screenshooter. One can sub scrot for that. Google will tell you how.

I've been using 'maim' for a long while now - best no-gui screenshooter!
Example:
5s Delay before it takes a shot of the whole screen, without the pointer.
