# By default, Red Hat 6.0 and later now use a font server independent of

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
#       Option  "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
#       Option  "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
#       Option  "XkbModel"    "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
#       Option  "XkbModel"    "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#       Option  "XkbLayout"   "de"
# or:
#       Option  "XkbLayout"   "de"
#       Option  "XkbVariant"  "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
#       Option  "XkbOptions"  "ctrl:swapcaps"
# Or if you just want both to be control, use:
#       Option  "XkbOptions"  "ctrl:nocaps"
