I followed this advice Default save directory for gnome-screenshot? and installed it as the top answer suggested.
But the "screenshot" does not appear (see image). https://www.dropbox.com/s/ud2p8bv8v3z0w9m/snapshot7.png?dl=0
And here is my installation https://www.dropbox.com/s/c0gnxuead911dzc/snapshot8.png?dl=0
Edit, myabe this should be a different quesiton now, but I looked in the preferences for Ksnapshot and googled for it but could find no way to do it.
What I want to achieve is: each time I press PrtSc or ctrl+prsc I save a file named
and then the URL is pasted to my clipboard.
