I'm on Xubuntu 12.04. I use Hebrew as well as English US.
When I installed Xubuntu I added Hebrew via the Keyboard Layout settings and set ALT-SHIFT as the change layout shortcut. In both cases when I've installed Xubuntu, this worked well and no issues.
After everything worked fine on this laptop, it all of a sudden started to misbehave. Every time I restart, the Keyboard Layout settings revert to only US and the change layout shortcut is forgotten. I re-add the language and update the change layout shortcut and it forgets it again after reboot.
I don't believe I've changed anything, but I must have (or an update caused it?).
Where is the keyboard layout configuration saved?
