But with modern monitors (I'm not sure of the spec, I think is part of the VESA compliance requirements) the video driver can query the monitor for what refresh rates and modes supported by the monitor. Back in the day, indeed! True, but all monitors currently in use or available for sale are not necessarily compliant with the spec, or with the current spec. Perhaps they're older models, hand-me-downs or remaindered at a store. Compliance or incomplete compliance with specs such as VESA are not particularly a deal-breaker (or even much mentioned) when buying a monitor, and there's no explicit reason that anyone might choose a modern monitor rather than a remaindered one (a model that is no longer actively produced by the manufacturer, but unused units of the product remain at the store's warehouse), and of course if one buys an off-the-shelf computer (Compaq, HP, Packard Bell) that comes with a monitor, you have no idea or choice what you in fact are getting in terms of modernity-- most likely such a no-longer-produced model is the one provided, to reduce costs. Because, really, if the monitor displays acceptably, why should Compaq or HP or PacBell particularly care to provide the very most recent model, for which they must pay more (and pass the extra cost on to the end buyer)? How many people actually ask the monitors specific specs in such a situation? And further, monitors may be actively limited in specification, the way mine is. I'm almost sure that I've tried autodetection at least once (when the head of the ATI team said that the new drivers were better served by having a relatively empty xorg.conf, and that autodetection was now working in fgrlxconfig/aticonfig). Unsurprisingly, my monitor was again limited to [EMAIL PROTECTED], and I had to insert my refresh rates in order to get [EMAIL PROTECTED] But of course, since the actual monitor specs are not all that critical to the average user, the average user who owns this model probably doesn't even know that the monitor is capable of 1280x1024 (and if they want that resolution, they buy a new monitor), and are satisfied to eat what they're given, as it were. That's fine for those who find it fine, but I've gotta say, it really burned me, just on the principle of the thing, to discover that my monitor was had capabilities that were actively concealed from me, for my own protection I suppose. This is what the DDC module in X is for, and why monitors no longer require 'drivers' (which was never a 'driver' anyway, just a .inf that told the video driver what the possible modes were). All monitors do not correctly report their DDC information, flatly put. Sometimes because of active limitation as I experience, or because they're cheaply made (just well enough to hit the mark, rather than with strict compliance to spec), or simply because they were made before the spec was implemented. After all, on anyone's standard upgrade list, how high priority is really the monitor, as opposed to the CPU, the mobo, the memory, the video card-- even the sound card or network hardware? Who really bothers if the monitor works (meaning, displays without corruption)? All of which means, yes, you have a point, and in many (possibly even most) situations you're probably right, but there is still a place for knowing your monitor's actual specifications, and there is still a place/reason for inserting such specs actively into xorg.conf. I stand by know your specs. :-) . Holly -- gentoo-user@gentoo.org mailing list

Of course if you just give up on CRT monitors, and only buy LCD, you don't have to care about refresh rates to begin with!

Current x.org versions should be able to auto-detect the VertRefresh and HorizSync settings, as well as appropriate modelines. So I would comment out all such stuff from your xorg.conf file, and see if the autodetection will work. Probably the easiest way to do this will be: mv /etc/X11/xorg.conf /etc/X11/xorg.conf.save X -configure (follow the printed instructions for testing the generated config) mv path from X -configure /etc/X11/xorg.conf You may have to change /dev/mouse to /dev/input/mice in the generated config before it will work. Then you can diff the generated config with your old one, and see what settings you want/need to keep.

Generically modeline is the path to doing this. (I think...) I've done similar things using this site: http://koala.ilog.fr/cgi-bin/nph-colas-modelines That's a good suggestion, but what all the replies so far seem to miss is the fact that refresh rate is a *monitor* setting, not a video card setting (although, because the monitor is a part of the X server-- along with the video card, mouse, and keyboard-- the possible refresh rates are also set in xorg.conf). So the possible refresh rates for any given resolution rely on the monitor's capabilities, not those of the video card. From my own experience, this can sometimes be tricky, depending on the monitor. For example, my monitor is a 17 Eizo F550i-W. From the Eizo site (I don't have a manual, as this was a hand-me-down from an office that was upgrading), I found that the monitor is capable of 1280x1024-- but [EMAIL PROTECTED], which many people find uncomfortable. That's not the problem, though, if I want to use 1280x1024 (which I do); the problem is that Eizo lists their monitor under both Windows and X, meaning that they provide drivers for it, which I can use by selecting the monitor's manufacturer and model during setup (under either Linux or Windows). Except that the manufacturer-provided drivers are *limited* by the manufacturer, to the optimal resolution of [EMAIL PROTECTED] So under either Linux or Windows (when I was still using Windows), I could not use the manufacturer-provided drivers for the monitor, if I wanted to use a resolution of 1280x1024-- that resolution was not available, because the monitor only displays that resolution at 60Hz, and Eizo doesn't want me to use a 60Hz resolution. The only way I am able to set my desktop to [EMAIL PROTECTED] is to not use the manufacturer-provided driver; under Windows I used Generic VESA 1280x1024, and under X I must set my Horizontal and Vertical refresh ranges manually (provided on the manufacturer's site, or in a manual, if I had one). Under X, as long as the ranges are set correctly, X knows that the monitor can display at 1280x1024, and sets the refresh to 60 automatically for that resolution (because the ranges I've given tell it the correct combination of possible resolutions and refresh rates that can be displayed). The point being, you need to know your monitor's specs. Is it in fact capable of displaying [EMAIL PROTECTED] If so, the same place that told you that should tell you the refresh ranges of the monitor. Plug those into xorg.conf rather than whatever defaults might be there (which for me are usually off by quite a bit, especially the horizontal range), and the problem should sort itself after restarting the X server. You can also do this with modelines, but I don't understand them (meaning, I can't look at a modeline spec and know what it's trying to do so that at need I could plug in my own), and so don't bother with them. Hope this helps. Holly -- gentoo-user@gentoo.org mailing list
