you can add:
Option "Disable" "TRUE"
to the monitor section for LVDS if you don't want the LVDS to be on by default.
Alternatively, you can set the following option:
Option "IgnoreLidStatus" "FALSE"
which will use the acpi /proc lid status to to decide whether to
enable LVDS or not. Note, the acpi bioses are broken on many systems
