Re: Dual Head Video Cards

[Bikehead <bikehead@xxxxxxxxxxxxxx>]

I'm sorry if this is a newie question, but are you using two NVidia 
cards or one?  I have two nvidia cards: one in the AGP slot an the other 
in a PCI slot.  I can use dual head with the NV driver no problem.  
However, when I try to use the nvidia driver it locks the machine: its 
almost like the nv driver can't handle the fact that there are two 
cards.  If I remove the second card declaration from xorg.conf,  I can 
get the one screen/card to work. 

I have noticed that there is something called "Twinview" which seems to 
be an NVIDIA thing which I'm guessing drives two monitors from one card?

So if you are using two cards, how did you declare the two cards in the 
xorg.conf?  Did you have to load the kernel module in some special way?

Thanks,
