Dunno about the other problems but those two behaviors are normal.
~/Desktop is a standardized location so both desktop environments
will see a .desktop file dropped there.
Well some window managers will use that for any file that's visible on
the deskop.
And that location can be changed, there's a file that configures what
actual directory is used for the desktop. It's important for
internationalisation of the computer, so that everyone gets common
folders in their own language.
The monitor config is different though. mate-display-properties and
Gnome's tool will store information in their own place and in their
own way. You will have to configure it in both.
For MATE, and perhaps others, it's a monitors.xml file
$ locate monitors.xml
/etc/mate-settings-daemon/xrandr/monitors.xml
/home/tim/.config/monitors.xml
The first would appear to be a default, the second is one when I set up
my system (it'll be an override).
And good luck getting one of them to actually save the default
the login box will use
The login screen runs as its own user, and you can copy the
configuration file (that you use) into their homespace.
It's necessary that ordinary users can't change the login screen, at
least on multi-user systems that you don't own. Only an admin should
be able to that. The login screen is a security function.
