Comment 463 for bug 1218322

I'm using now Ubuntu Gnome 14.04 and I am affected by the bug. It was not existing in Ubuntu 12.04.

In the gnome-control-center I cannot assign Shift+Alt (or any other combination of Shift, Alt, Ctrl) at the options "Switch to next source" and "Switch to previous source". I can assign to the option "Modifiers-only switch to next source", but although it change the layout in the panel, it does not change it effectively and I am still typing with the previous one.

In gnome-tweak-tool, assigning "Switch to another layout" changes "Modifiers-only switch to next source" option from the gnome-control-center and it does not help.

I solved this problem using the command
            gsettings set org.gnome.desktop.wm.keybindings switch-input-source "['<Alt>Shift_L']"
that assigned Alt+Shift_L to the option "Switch to next source".
