Don't bother trying. If it works when you leave them unspecified, don't think any more about it. If it still doesn't work however, the easiest way is to construct a valid modeline specific to your monitor. Xorg can actually tell you what to put into your xorg.conf, see section 5.4.3.2 of the FreeBSD Handbook [1] The quickest way to get these values out is to grep your Xorg log (even from a failed run of Xorg). Eg (quoting from the Handbook) : $ grep -A 4 'Supported additional Video Mode' /var/log/Xorg.0.log (II) I810(0): Supported additional Video Mode: (II) I810(0): clock: 108.0 MHz Image Size: 340 x 270 mm (II) I810(0): h_active: 1280 h_sync: 1328 h_sync_end 1440 h_blank_end 1688 h_border: 0 (II) I810(0): v_active: 1024 v_sync: 1025 v_sync_end 1028 v_blanking: 1066 v_border: 0 (II) I810(0): Serial No: ETL5108015 This information is called EDID information. Creating a ModeLine from this is just a matter of putting the numbers in the correct order: ModeLine <name> <clock> <4 horiz. timings> <4 vert. timings> Heres one I made earlier (unfortunately, not the one from the log, that one works 'out-of-the-box') ModeLine "1680x1050" 146.0 1680 1784 1960 2240 1050 1053 1059 1089 Cheers Tom [1] http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/x-config.html --=-FHiQ4o+FlsZQntsHW0np 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) iD8DBQBGNiKjlcRvFfyds/cRAuRLAKCSSkAtNTtkiKFvGk+hqVdx9SZH5gCfd4tU lg0f7DdLQMqN7R41ZyK4zdM= =QvBH -----END PGP SIGNATURE----- --=-FHiQ4o+FlsZQntsHW0np--
