Debian Dual Monitors With Intel and S3

jmoschetti45 · 06-19-2011, 04:47 PM

I have a 19" and 14" flat panel. There's the onboard Intel graphics, and an old PCI S3 ViRGE card I had laying around.

Figured I could make this into a dual head box.

Intel is the default display in the BIOS.

So far, with the attached configuration, I have the main monitor working properly at 1280x1024@60Hz. Nothing at all on the other monitor. It needs to run at 1024x768@60Hz. If it matters, running Squeeze with LXDE.

Any ideas? First rodeo with dual's in Linux...

As far as I know, running 2 different type video cards (eg ATI and nVidia) is linux is not at all easy.

Considered getting an dual head AGP card and using that instead? You can get very cheap AGP cards these days.

Older machine without an AGP slot.

Thats a pity, PCI video cards are a lot more expensive than AGP cards.
