7900GS Card and Multi-Headed Display ...

[scrappy]

'k, I've tried to search google (even with site:http://www.nvnews.net to narrow it down), and I'm drawing a blank, so I'm asking here ...

I picked up a nice new system the other day, 64bit, Dual Core and running 6-STABLE on it ... 7900GS Dual DVI video card ... now, I've read/know about the 64bit issues with the driver, but from what I've been able to tell, I should be able to do this with just the nv driver that comes with X.Org 7.x ...

Now, I've included my current XF86Config file ... it starts up X, but on the second monitor, it looks like I'm getting a mirror of the first monitor, but all 'low res', for a lack of better way to describe it, and 'flashing' ... for instance, if I move the browser window right-left on the 'good screen', the 'bad screen' shifts right-left also, to match ... so I'm obviously missing *something* important here

The only way I could get the current configuration to even start, without getting:

Fatal server error:
Requested Entity already in use!

was by changing the BusID to PCI:1:0:1 (or anything) even though nothing seems to turn up in pciconf other then pci:1:0:0 ...

none1@pci1:0:0: class=0x030000 card=0x221f19f1 chip=0x029210de rev=0xa1 hdr=0x00
vendor = 'NVIDIA Corporation'
class = display
subclass = VGA

So, the question is ... what am I missing, or is the nvidia kernel driver a requirement to getting dual-head working after all?

Thx ...

Last I heard, the open source 'nv' driver does not support multihead configurations on the same card.

I concur , dual head on the same card doesn't work with the nv driver.

Xorg nv driver versions >= 2.1.0 include rudimentary dual-head support for pre-G80 hardware; more flexible dual-head support is available for G8x series hardware.

Ya, tried that ... probably good with two identical monitors, but I'm using two different ones

I ended up booting up my old computer (it has an nvidia card in it too, of course) and hooked the second display up to it, and am using synergy to connect the two ...

someday, maybe I'll be able to use the 'full card', but after talking to the FreeBSD kernel developers, I think it falls under 'not any time soon' ... seems that the list of things to do are required for more then just the nvidia stuff, just nobody has much time to implement them *sigh*
