Hi Aleksej,
in tazx under section
# Generate or regenerate 40-Keyboard.conf
under "case "$keymap" in" there are three lines for the Slowenian (Slovenski) keyboard layout:
slovene)
# Slovenian
layout="si"; options="grp:alt_shift_toggle, $options" ;;
which are useless, because the keyboard layout should be "sl" but not "si", but You don't need those three lines anyway, because there is no second layout and because You don't need a second layout for the slovene.kbd like in Greek or Russian, which need the use of Latin script. I have been in Slovenia and can tell You, that they don't use Cyrillic script, they use the Latin script. Maybe Slovenian and Serbian was mixed up. The Cyrillic script is used in Serbia and their layout is different to to Russian layout. So I think, those three lines make no sense and should be deleted. Please delete those lines or tell me that I am wrong and change it in a way that it makes sense.
