I'm running two keyboard layouts on my system. US and US dvorak. I noticed today, when I change between the two the toolbar icon is changing, but the actual layout doesn't.
The only way to change keyboard layouts right now is running
sudo dpkg-reconfigure keyboard-configuration
Upon which all layouts change to the chosen layout. This layout is also displayed as the "Keyboard layout chart" regardless of the actually chosen keyboard layout. Keyboard layout chart shows Dvorak layout, even though standard US layout has been chosen
Adding and removing layouts in "text entry settings" does nothing. Nor does launching ibus-setup from console.
I've been using the standard procedure as in http://www.wikihow.com/Change-Keyboard-Layout-in-Ubuntu for years. Always worked. The layout-changer works superficially as usual, but no matter which layout is chosen, it always behaves like the system-standard (in this case: dvorak) layout and is also displayed as such in the Keyboard Layout Chart.
