In alt.os.linux.slackware, Ori dared to utter,
>> How are you using your dual-head?
>> The standard Nvidia drivers?

The one difference I ahve noted is that both of my monitors run at the
same resolution, which may make a difference, I don't know. I'm using
the drivers I downloaded and installed from Nvidia's website on the
23rd of June, 2003. I don't know if these are the most recent version,
but they work very well, so why upgrade them?

Here's a copy of my XF86Config
