</div>Interesting problem. My low-end nvidia card has no trouble with two<br>
monitors, but I have no idea how I would go about adding a third.<br>
<br>
We have a computer in my lab with 5 monitors on it using nvidia, but<br>
alas, its Windows.<br>
<div></div></blockquote><div><br>The issue with the nVidia drivers is that the hardware makes it an either/or proposition. You can have either compositing or xinerama, but you cannot have both, at least with the nVidia driver. The xorg people point the finger at nVidia and nVidia points the finger at xorg. In any case, using xinearama is essentially deprecated in favor of xrandr1.2 which does all sorts of wacky stuff, like rearranging monitors on the fly, partial monitor overlap, hotplugging output devices. If you've ever had to give a presentation with a laptop, xrandr1.2 is a godsend.<br>
<br>I'm inclined to believe it's nVidia's fault. The intel drivers and newer opensource ati drivers have no problem with this.<br></div></div>
