Let your computer do the math work :-) $ xmode -x 1200 -y 800 122 140 Modeline "1200x800" 200.26 1200 1296 1424 1648 800 801 804 868 That is on my box, you may have other values. Try it!

Whoever is responsible for commenting all the files in xorg.conf.d/ should have added a README there. As not every distro populates xorg.conf.d/ (actually none that I can remember other than openSUSE), I have to think the presence of anything there at all may well be an exclusive openSUSE feature, and a README addition is worth an openFATE try.

What you need depends entirely on why you're trying to override automagic. What is the problem you're trying to solve?

Why such a bother with modeline calculation? Xorg calculates suitable modelines automatically. I cannot remember _EVER_ solving any problem by putting a modeline in any Xorg config file (unlike for XFree86), though I do remember multiple attempts to do so. -- "The wise are known for their understanding, and pleasant words are persuasive."

Its largely un-needed these days. But I recall more than one older video card that offered modes that the monitor could not actually handle, which would send the screen into a hash of slanted lines and the fly-back transformers squealing bloody murder. You would typically have to specify each modeline in detail to avoid these that the card was technically capable of, but the monitor wasn't. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
