Xfree Dual Monitors and Nvidia...


Any Help Would Be Appreciated. TIA

I Have setup my GeForce Drviers and have also configured XFree for my Dual Montiors, I am sorta a newbie and the problem is XFree is telling X to spitout diffrent H and V syncs to bboth my monitors because when i check my monitors built on system, both monitors are running and diffrent H and V syncs. I cant figure out why from my XFREE file. I will post it and will some expert please correct this problem for me. The second monitor looks100% its the first im having problems with the first.

I haven"t used a twinview capable nVidia, but in my exeperience with other dual head cards, the second head is powered by a cheaper and slower clock, which means that the second head can't get to as high a refresh rate as the first. You may want to dig up some modelines (look through a sample XF86Config file for them, should have one in /usr/share/doc/whateveryourdistributioncallsXprobably"xfree86-server"orsomethinglikethat
If you explicitly set one for the resolution you use, then it will take precedence over X's normal behavior of getting the highest refresh rate possible.

Also, it looks like you only have one Monitor defined, I dunno if this is standard for twinview on X. If not, it may mean that X may not be detecting the second monitor's refresh rates automatically. Try adding a second Section "Monitor" with an ID of Monitor1, and copying the settings from Monitor0

Also, while you're playing with your config be sure you're not using xdm or any other *dm that automatically tries to start X. If something goes wrong and it fails to start, it will keep trying to restart it, making the system mostly unusable (though I've heard that newer versions fix this problem)
