Follow the FBSD handbook to do a 'Xorg -configure' and a test run of X with the generated Xorg.conf file. Then have a look at your your '/var/log/Xorg.0.log'. You will find a log of X using DDC to interrogate your LCD screen for it's capabilities and the acceptable modelines A snippet of my Xorg.0.log file ---------------------- (II) Loading sub module "ddc" (II) LoadModule: "ddc" (II) Loading /usr/X11R6/lib/modules/libddc.so (II) Module ddc: vendor="X.Org Foundation" compiled for 6.9.0, module version = 1.0.0 ABI class: X.Org Video Driver, version 0.8 (II) NV(0): I2C bus "DDC" initialized.
