/etc/lightdm/lightdm-gtk-greeter.conf and a keyboard chooser appears, but I cannot for the life of me get it to list multiple keyboard layouts. I am on Lubuntu 14.04. Have tried using
unity-control-center to add a layout. Adding a layout to my ibus. Tried forcing the gsettings on the lightdm user (they seem to get regenerated / overwritten on reboot). I did this to my
XKBMODEL="pc105,pc105" XKBLAYOUT="us,us" XKBVARIANT="dvorak,"
If I invert the order of those pairs then I get QWERTY only option in lightdm, and if I have them like this I get the Dvorak only option in the drop-down, but I still cannot find a way to make it list both of them.
I have multiple users on this computer that each prefer to type passwords with a different layout, so I really need this feature.
Does anyone know how to do this?
