Comment # 6 on bug 1031925 from Stefan Dirsch

I need to clarify that you need to run localectl as root, but test keyboard
configuration in Xsession as freshly created user. Sorry for the confusion.
Please give it a another try. Thanks.

[    57.124] (**) Option "xkb_layout" "hu"

Seems you somewhat managed to switch default Xserver config configuration to 
"hungarian".

BTW, after issuing localectl command new keybaord layout should occur in 
/etc/X11/xorg.conf.d/00-keyboard.conf.
