Guys, I need help setting my LCD to output native 1280x768 or 1366x768 is
even better.  I tried Jarod's Powerstrip method, I can get 1280x768 in
Windows (albeit black bars on the side) and 1366x768 looks horrible so I
gave up on try that.  So I copied the modeline for 1280x768 into xorg.conf,
but it's being ignore for some reason, I can only get 1024x768.

I attached my xorg.conf and Xorg.0.log if any kind soul would diagnose for

# To customise the XKB settings to suit your keyboard, modify the

# 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:
