Default 3 Monitors w/ 2 NV solutions?

I have very little need of 3D graphics. If problematic, I can live without it. I mainly do 2D work, and only on DFPs that have DVI inputs. (Right now, two Samsung 213T.) I use x.org, version 7.0, via gentoo.

Now, I already own an ASUS A8N VM CSM motherboard-based linux system, that I use as a dual monitor solution. I am pretty pleased with it, although the VGA output could be cleaner. At 1600x1200, the inferior quality of the VGA output compared to the DVI output is quite apparent.

Now I am thinking of adding a 24" DELL 2405 or 2407 monitor. Together, these three still cost less than one 30" monitor.

However, I am wondering whether there is good linux support [and sample xorg.conf files] for adding a third monitor via a PCI-E card. the PCI-E card itself would drive two monitors, presumably via dual DVI (I also like no-fan cards; recommendations?), the a8N motherboard would drive the third monitor (again DVI).

is this a good or a bad idea?


second question---same one for Apple OSX. are there affordable three monitor DVI solutions for Apple hardware, too? can computers take 2 video cards, not for SLI linkage but just to provide more outputs? [I know, we don't know about the new PowerMacs yet, though I am toying with the idea of moving from linux to OSX when the core 2 duo powermacs are coming out.]

advice appreciated.

sincerely,

/iaw

It is possible to drive three screens using two videocards. You need to perform some xorg.conf magic for it. You can find various examples if you search the forum as more people did it before you (mixing twinview with an additional videocard using xinerama)

I have no idea about OSX. I don't know whether the OS supports multiple videocards well (you would need a pci and AGP card both ofcourse with a ppc bios). Future powermacs could feature multiple pci-express slots and then it might be possible assuming OSX supports it aswell.

Here is my simple xorg.configuration to use three old CRTs. I have GeForce 6600GT and GeForce 6150 integrated on MB. I hope it will help You to setup new configuration.
