Please check you have a directory called 'Pictures' in your home directory and create one otherwise.

Please also attach a copy of this file from your home directory: .config/user-dirs.dirs

[Yannik (yannik-5)]

There is no directory 'Pictures' (or a similar named directory in my locale) in the home directory.

Here's the .config/user-dirs.dir:
XDG_DESKTOP_DIR="$HOME/Schreibtisch"
XDG_DOWNLOAD_DIR="$HOME/Downloads"

Screenshots were saved to $HOME in the past, not a 'Pictures' a directory.

We really do not want to add a Pictures directory, because we want to encourage our users to save their files on their smb-mounted home on our server.

How can we change the path where the Screenshots get saved?

[Daniel van Vugt (vanvugt)]

Try adding a new line to that file:

XDG_PICTURES_DIR="$HOME"
