# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of

# 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

# Option "XkbOptions" "ctrl:swapcaps"

You may need to change the following lines. I think they are too high:

HorizSync 30.0 - 96.0
VertRefresh 48.0 - 120.0

You may want to get the range from the manufacturer or run the following command to get what's detected:

hwinfo | grep -e Hor -e Ver

You may need to install hwinfo first. Drop me an Email if it worked.
