You should not need to specify HorizSync or VertRefresh. FYI here is my conf: Section "Monitor" Identifier "HomeTFTMon" ModeLine "1680x1050" 146.0 1680 1784 1960 2240 1050 1053 1059 1089 EndSection Section "Screen" Identifier "HomeTFT" Device "Card1" Monitor "HomeTFTMon" SubSection "Display" Depth 32 Modes "1680x1050" EndSubSection EndSection =20 (The entire conf is a little more complex, dual head on a laptop..) The relevant section of the handbook is 5.4.3.2 'Adding a Widescreen Flatpanel to the mix' [1]. To get the values for the modeline, check in your /var/log/Xorg.0.log . This should help you do the trick: grep -A 6 'additional Video Mode:' /var/log/Xorg.0.log Cheers Tom [1] http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/x-config.html#AEN= 6461 --=-8A70mrcbSX//bUwJBFTZ Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQBGH3ABlcRvFfyds/cRAsrhAKCuileWFBNqUrL3j7pY+glm+r4QUgCgl+cr yzWl/oR3eTXL3sK28R6At3Q= =C6qP -----END PGP SIGNATURE----- --=-8A70mrcbSX//bUwJBFTZ--
