So let me get this straight, I thought AGP was the slot in the motherboard for inserting a graphics card. But from they way people are talking, the graphics chip built into the motherboard is also AGP? I had, perhaps wrongly, assumed that using the AGP slot would automatically override the onboard chip. I had never thought of looking in the BIOS. I'm going to get back to Debian over the weekend and try and sort these issues out, I've been kind of busy this week doing photoshop work. Eventually I'd like to see what graphics software there is for gnome, but I expect it will be a while before I give up photoshop completely. Simply because its hard for an artist to adjust to a new medium.
HI, It's been a while since I worked on component level stuff (not since the very early days of P4's). But the AGP bus used to support only 1 device reliably. On board graphics chips can exist on wither the PCI or AGP bus - dependant on the type of chip. Nowadays I'd expect all to be AGP. Bioses may have options for turning off on board graphics - this option used to be rare, I don't know if it still is. IIRC, if you plugged an AGP card into a motherboard with onboard AGP, all sorts of strange things could happen. If it has an AGP slot as well as onboard AGP I'd expect there to be 1 of the following: 1) an option for turning off the on board chip 2) special drivers to allow both AGP devices to be used - ie as dual monitors. For the drivers, you'd have to find out what it actually supports - the odds are you'll be looking at the actual motherboard chipset drivers (ie what used to be the north bridge) rather than the graphics drivers. Whether there's support for something like this in the linux drivers I don't know - you'd be best asking on a relevant list for the drivers in question.
