Comment # 13 on bug 1209594 from Giorgio Gallo

This is /usr/etc/X11/xdm/keytable, rewritten with the logic "straightened up"
in a way that IMHO makes it much more readable and with the additional
"localectl set-x11-keymap".

IDK if this rewrite is worth the hassle of testing and risk of regression...
just including it in case it's of any use.

# files ($vconsole_conf_file and, depending on version, $systemd_x11conf_file

# To make sure it is consinstent everywhere, this scripts calls localectl with
# the configuration from $vconsole_conf_file, which will cause the various
# configuration files to be updated as neeeded.
#
# Moreover, this script also removes $previous_x11conf_file if it seems safe
# to do so.
