First, a quick thank you to everyone that's chipped in on this. I've run across, and also been pointed toward, several modeline generators. I present to you three of them:
1. http://www.sh.nu/nvidia/gtf.php 2. http://www.dkfz-heidelberg.de/spec/linux/modeline/modeline2.cgi 3. http://xtiming.sourceforge.net/cgi-bin/xtiming.pl All of them offer to pump out a modeline for you after you input the values of the Fh and Fv ranges, and the resolution and refresh you want to run at. Wow, what convenience. Using the values of Fh = 30-97, Fv = 50-160, and 1024x768 and 100 Hz refresh however (you know what is coming, right? <vbg>) produces the following three DIFFERENT modeline calculations: (numbers correspond to the URLs above) 1. # 1024x768 @ 100.00 Hz (GTF) hsync: 81.40 kHz; pclk: 113.31 MHz Modeline "1024x768_100.00" 113.31 1024 1096 1208 1392 768 769 772 814 -HSync +Vsync 2. # V-freq: 100.00 Hz // h-freq: 81.70 KHz Modeline "1024x768" 124.84 1024 1088 1240 1528 768 768 771 817 3. Modeline "[EMAIL PROTECTED]" 126.64 1024 1056 1536 1568 768 781 794 807 I ask you . . . are we having fun yet? The values wildly disagree with each other, but since this is presumably a precise mathematical calculation, only one of them can possibly be correct, but indeed NONE of them NEED be correct of course. It's possible they are all wrong. Certainly someone in "the community" who is really "in the know" ought to have a look at these discrepancies, I would think, and set the record straight for everyone else? I certainly don't want to plug the wrong modeline in and fry a very nice monitor. And I'm simply not qualified to calculate my own modeline, since I don't clearly understand the math behind it. Obviously, from the results above, I'm not alone on that score, and even people who think they know what they are doing well enough to put up programs for others to use may indeed be flailing around in the dark. Unless I am completely mistaken about this concept (a possibility, I readily admit) at least TWO, if not all three, of the modelines generated above are worthless, and maybe even dangerous to use. One thing that might help me decide if I want to take a chance on one of these modelines: Can anyone reading this input your own numbers to any of the three generators and get a modeline that matches the one that you are using in XFconfig-4? That would be very interesting information to have. Lance
