Basic dual monitor question


Hello,
I use Mandrake 10.0 on a laptop with KDE and love it. I would like to install Mandriva 10.1 (or whatever the latest version is) on my desktop machine, but I am worried about compatibility with my dual monitor configuration. I have read various posts that discuss specific hardware issues with a dual monitor setup, but I would just like to know: what are the best video cards (I assume I need two) to use with Mandriva/KDE to have the easiest possible dual-monitor setup? Is there a walkthrough somewhere floating about on the internet?
Thanks!

as long as each one works ok in it's own right, then really you'll be fine, as Xinerama extensinos and such, operate above the level of hardware. I'd suggest a real dualhead card, like my geforce ti4200, as with that you can actually enable the dual head stuff within the driver for the device, and not join two devices together at the end.

I'm not to fond of dual head cards (not enough heads) I've got 3 cards I think youll want atleast one nvidia card for opengl but as long as each card works by itself you should be able to make it work as a multihead system. If youd like I could post my xorg.conf

not to offend you but I don't see the point of the dual head card. they are expensive and AFAIK opengl 3d doesn't work with multihead (only my center screen has 3d acel.) (unless your dual head card makes the computer see it as 1 card with 1 wide screen in which case you are kind of limited to 2 screens) so why have an expensive dual head card when I can have a nice NVIDIA agp card for the center then use any old pci cards for the others plus I can add more screens if I wan't

dual head cards aren't expensive in the slightest. normally adds about 40% to the cost, so much cheaper than seperate cards. Maybe you're thinking of the more traditional Matrox offerings? personally i don't use twinview on my geforce, and so they work wholly independently and great, with gl and everything i've ever wanted to throw at it.

much cheeper then seperate new cards (I'd sill bet your one card cost more then all 3 of mine. {a riva and 2 s3s}) when using your card as seperate cards do you get gl on both screens? if so what happens when you try to run gl in fullscreen mode?

Cool. Is it usually straightforward to do this? How does this card look? The specs say it works with linux and it has dual VGA:

Although I'm also wondering if maybe two DVI cards might be a better option. I haven't really researched the differences very carefully.
Thanks for your help guys!

looks fine. only worth caring abuot dvi if you actaully use dvi hardware. personally my card has 1vga and 1dvi and i use a dvi to vga adapter for 2 vga outputs.
