Setting in xorg.conf was the only way before xrandr existed. Setting in xorg.conf may cause those settings to be applied sooner as well, so that they affect any GUI login manager that might be starting, instead of at later window manager startup. Also, you *should* need *no* modelines if you include valid values for these three options: VertRefresh HorizSync PreferredMode I've *never* needed to include modelines to produce the resolution I want. Xorg knows how to auto-generate modelines quite well given those basic substitutes for a display's EDID. -- "Wisdom is supreme; therefore get wisdom. Whatever else you get, get wisdom."
