How to make ubuntu respect my choice of keyboard layout when keyboard is replugged

I've found that if I disconnect my USB keyboard and reconnects it it seem to resort to using "standard" US layout, but I want US intl. layout (the same layout as in windows). In order to make that happen I have to after I reconnect the keyboard select another layout and then US intl. which is rather annoying since it means that I have to do this rain-dance each time I connect the keyboard (besides I also have to have another keyboard layout installed that I don't intend to use, but have to have in order to change the layout).

I've tried to run dpkg-reconfigure keyboard-configuration, but with no luck.

Before I disconnect the keyboard, with appropriate keymap I get:

> cat /etc/default/keyboard 
# KEYBOARD CONFIGURATION FILE

# Consult the keyboard(5) manual page.

XKBMODEL="pc105"
XKBLAYOUT="us"
XKBVARIANT="intl"
XKBOPTIONS="lv3:ralt_switch"

BACKSPACE="guess"

> localectl status
   System Locale: LANG=en_US.UTF-8
                  LANGUAGE=en_US:en
                  LC_NUMERIC=sv_SE.UTF-8
                  LC_TIME=sv_SE.UTF-8
                  LC_MONETARY=sv_SE.UTF-8
                  LC_PAPER=sv_SE.UTF-8
                  LC_NAME=sv_SE.UTF-8
                  LC_ADDRESS=sv_SE.UTF-8
                  LC_TELEPHONE=sv_SE.UTF-8
                  LC_MEASUREMENT=sv_SE.UTF-8
                  LC_IDENTIFICATION=sv_SE.UTF-8
       VC Keymap: n/a
       X11 Layout: us
       X11 Model: pc105
       X11 Variant: intl
       X11 Options: lv3:ralt_switch

> setxkbmap -print
xkb_keymap {
    xkb_keycodes  { include "evdev+aliases(qwerty)" };
    xkb_types     { include "complete"  };
    xkb_compat    { include "complete"  };
    xkb_symbols   { include "pc+us(intl)+inet(evdev)+level3(ralt_switch)"   };
    xkb_geometry  { include "pc(pc105)" };
};

But after disconnecting the keyboard and reconnecting it gives:

> localectl status
   System Locale: LANG=en_US.UTF-8
          LANGUAGE=en_US:en
          LC_NUMERIC=sv_SE.UTF-8
          LC_TIME=sv_SE.UTF-8
          LC_MONETARY=sv_SE.UTF-8
          LC_PAPER=sv_SE.UTF-8
          LC_NAME=sv_SE.UTF-8
          LC_ADDRESS=sv_SE.UTF-8
          LC_TELEPHONE=sv_SE.UTF-8
          LC_MEASUREMENT=sv_SE.UTF-8
          LC_IDENTIFICATION=sv_SE.UTF-8
   VC Keymap: n/a
  X11 Layout: us
   X11 Model: pc105
 X11 Variant: intl
 X11 Options: lv3:ralt_switch
> setxkbmap -print
xkb_keymap {
    xkb_keycodes  { include "evdev+aliases(qwerty)" };
    xkb_types     { include "complete"  };
    xkb_compat    { include "complete"  };
    xkb_symbols   { include "pc+us(altgr-intl)+inet(evdev)+level3(ralt_switch)" };
    xkb_geometry  { include "pc(pc105)" };
};

> gsettings get org.gnome.desktop.input-sources sources
[('xkb', 'se+dvorak'), ('xkb', 'se'), ('xkb', 'us')]

I note that localectl status doesn't seem to tell the truth here. setxkbmap -print however seem to tell that the keymap is no longer the same (and not what I think I requested in /etc/default/keymap)

It turned out that there were two places that one could configure the layout: in Settings > Keyboard > Layout and in the thingy on the statusline where you can switch current layout has Configuration > Input Methods. It turned out that the former contained a layout that I didn't want. Setting the layout there to to use US intl seemed to solve my problem.

Now the remaining question is more of curiosity, some explanation of this behavior (why, how etc). Should I take further action?
