# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a European
# keyboard, you will probably want to use one of:
#
#    Option     "XkbModel"      "pc102"
#    Option     "XkbModel"      "pc105"

# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#
#    Option     "XkbLayout"     "de"
#

# These are the default XKB settings for X.Org
#
#    Option     "XkbRules"      "xorg"
#    Option     "XkbModel"      "pc105"
#    Option     "XkbLayout"     "us"
#    Option     "XkbVariant"    ""
