Not having looked at dual head before I was unaware that the open source driver didn't do it. I'm sure I'd have found out eventually but you guys have saved me some head scratching time ;-) Screen res will be 1280x1024 on both and I'm using an i386 system. I'll probably end up with either a 6200 or maybe a 7600 if the budget will stretch.

Dual head video cards
Are there any "gotchas" I should look out for when purchasing a dual head video card? I'm currently looking for a cheap NVidia card with both analogue and digital output to use my old 21" CRT and the new 19" LCD but, as usual, there's very little info other than for Windows in the write ups/reviews. I've never used dual head before so I'm concerned that some cards might share resources to the extent that they are windows only . Maybe I'm seeing potential problems that aren't there? Budget is tight so I don't want to screw up the purchase. "Cheap" is word I'm looking for :-) -- Dave ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

"Cheap" > is word I'm looking for :-) You'll need to use the binary nvidia drivers, the open source nv driver doesn't support dual-head at all. So you run in to a couple of gotchas there. The first being that the nvidia drivers are i386 only, they aren't available for AMD64, and the second is that twinview has a sort of odd behavior when you use different resolutions on each monitor. It's hard to describe but the driver basically pretends that the resolutions are the same and then only draws what can be displayed of the smaller one, so there's desktop outside of the monitor that you can drag windows in to but obviously can't see. With regards to cards I've used the recent nvidia drivers and dual-head with everything from an fx5500 PCI card to 6200LE to 6600GT to 7200 cards. I've used the legacy drivers with various 4x00ti cards. Here are links to cards I've personally used with dual head in the sub $50 range USD. pci-e http://www.newegg.com/Product/Product.aspx?Item=N82E16814121080 agp http://www.newegg.com/Product/Product.aspx?Item=N82E16814127290 -- Thanks, Josh Paetzel pgpSHWjIMJuN1.pgp Description: PGP signature

There's some preliminary support for DualHead in xorg's opensource nv driver (starting with version 2.1.0, AFAIK), so it can be used with FreeBSD/amd64, but it doesn't play nice with Xinerama yet. Check Nvidia's documentation and release notes for drivers for more information. HTH, Yuri pgpWbDMeSnVJM.pgp Description: PGP signature

It allows you to span a single desktop across multiple monitors. I think that's what xinerama does. It works great for me and I have no performance issues. I'm currently using TwinView on a 5.2.1-RELEASE box and a 6.0-STABLE system. Using a GeForce4 Ti 4200 on the former and a GeForce FX 5700 Ultra on the later.

passively cooled pci-e dual head video cards for X?
I'm looking for a passively cooled pci-express card that will support dual-head w/ dvi lcd's on FreeBSD -STABLE. I'm currently using an AGP based matrox and it works well enough. I don't do anything 3-D, just a gnome desktop and various xterms and xemacs and stuff. The only fancy hardware acceleration I can imagine needing would be to support up-and-coming gnome eye-candy. I'd like a xinerama like effect (single desktop image), either w/ xinerma or card specific stuff (like the matrox). I've found these: http://www.nvidia.com/page/quadronvs.html which seem to almost cut it. Googling suggests that xinerma performance isn't usable, but that they do ok as separately managed desktops. Anyone else have any suggestions? g. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
