Ok, yet another try, this one will do the trick I hope... ;)
Credits are due to reverendj1, who described a way of assigning a Custom key to toggle keyboard layout, using setxkbmap, which featured in the workaround alluded to in Edit 2 of my previous answer...
Here is the slightly more involved way, but will give you more
flexibility for the key combination. First, copy and paste this script
I wrote and name it something like kb_toggle.sh. Make sure to edit
LANG1 and LANG2 to be the keyboard layout codes you need.
#!/bin/bash
LANG1="us"
LANG2="de"
CURRENT_LANG=$(setxkbmap -query | tail -n 1 | cut -f6 -d ' ')
if [ "$CURRENT_LANG" = $LANG1 ]; then
setxkbmap $LANG2
else
setxkbmap $LANG1
fi
make the file by right-clicking on it -> "Properties" -> "Permissions"
tab, then select "Allow executing file as program.
Now, open "System Settings" -> "Keyboard" -> "Shortcuts" tab and
select "Custom Shortcuts". Click the + button on the bottom and name
the shortcut "Keyboard Toggle" or whatever you want, really. Then give
the full path to the script you made earlier in the command box. Hit
Apply. Click where it says "Disabled" then you can set the shortcut to
whatever you want by clicking your key combination!
I think you'd need to change "de"
to "ir"
.
Again, good luck!
Edit
You may even get away with a one-liner, if you prefer:
setxkbmap us,ir -option "grp:alt_shift_toggle"
Now you can switch by pressing alt+shift

Edit 2
Depending on how you decide to achieve your goal, you may want to include lv3:ralt_alt
in your command, resulting in
setxkbmap us,ir -option "lv3:ralt_alt,grp:alt_shift_toggle"
See man xkeyboard-config | grep lv3
for details:
lv3:ralt_alt
Right Alt key never chooses 3rd level
xkeyboard-config provides the description files for the X Keyboard Extension (XKB). The configuration options below are
usually applied with setxkbmap(1).
Update 2017-04-13: This seems to have changed in recent Ubuntu versions and running sudo apt-get install console-common
will try to remove other packages. So, for recent Ubuntu versions, use this instead (Tested in 17.04):
sudo dpkg-reconfigure keyboard-configuration
The simplest way would indeed be as @steeldriver suggested to open a terminal and run this command:
sudo apt-get install console-common
That will install the console-common
package and in the process allow you to chose your console layout. If that is already installed, use this to bring up the same wizard and set the layout:
sudo dpkg-reconfigure console-data
Tested on 13.10, and taken from here.

Please try the following command:
If it says you don't have the package, then install console-data with:
