Using the default screenshot provided with Ubuntu 18.04, any screenshot of all my screens, or specific windows will cause the image to be saved to $HOME.
By default, the dconf value for /org/gnome/gnome-screenshot/auto-save-directory is '', which seems to be the home directory. Changing the value to either of the following has no effect:
/home/user/Pictures
file:///home/user/Pictures/
Replacing user for $USER makes no difference, either.
Is there a way to work around this? Alternatively, is it possible to set a command line option to save images to a specific directory, like:
gnome-screenshot -save /path/to/save
If so, I can simply bind the print screen key as such. However, I saw no mention of such an option in the man page.
I've noticed some similar questions which are a few years old have stated there was some bug involving this. I'm not sure if the bug would have existed for that long, but I'd assume it would have been solved by now if that was the case.
Perhaps something else might be overwriting the setting? Or am I making a false assumption that gnome-screenshot is being used? I haven't installed any screenshot related packages though.
As per the answer linked by pomsky (thanks) over here, the solution mentioned that due to a bug, the print screen button could not be used.
However, I was able to go to Settings > Devices > Keyboard and unbind the default screenshot buttons. I then created a custom bind for gnome-screenshot and gnome-screenshot -w as print screen and alt+print screen respectively, as they originally were.
Oddly enough, this solved the problem. The images now save to whatever I specified in the dconf editor.
