I only get the > ones explicitly listed. This has worked in both XFree86 and Xorg. In my case, using 6.1 Xorg, the only automatic modes suppressed were those whose resolutions matched one of the explicit modelines (and this is consistent with my reading of the 6.1 xorg.conf(5) manpage). Perhaps this behavior is different than earlier releases. The primary problem is that the highest-resolution automatic mode (1280x960) does not work: the (LCD) monitor displays a message to the effect that the input sync frequency is out of range, and goes into standby after about 20 seconds. This bad mode is used as the initial mode since it has the highest resolution, and there is no correct modeline that I can provide to override it because the resolution exceeds the monitor's capabilities; so the server always starts up in a non-working mode. I can get to a working mode with CtrlAltPlus, but then the desktop (which was sized according to the initial, invalid, resolution) is too big for the screen. I suspect I may have run into an Xorg (or driver) bug -- the probe did correctly identify the monitor as a Gateway FPD1530, and this should have caused all resolutions exceeding 1024x768 to be discarded -- but how do I get around it?
