After trekking through the graphics-card wilderness, I came up with an
R92LE-C3S (a.k.a. ATI Radeon 9200SE) which runs on the same generic driver as
the HP 6430NX motherboard's built-in graphics. Hence, my desktop looks
exactly the same as it did with the motherboard's video output. This is all I
could find with a search for graphics cards with Intel chipsets. Ha. Still
stuck with proprietary requirements. Blame my ancient motherboard.
Turns out that the first graphics card that I got wants a minimum of 450-watt
power supply, so it's going back. An MSI GeForce GT610 has a different socket
requirement that slipped past my radar. My old GeForce 6200 graphics card is
indeed DOA.
Is there a straightforward way of acquiring the ATI/Radeon graphics driver so
I can get round circles and not egg-shaped ones ? Anything I can get with
sudo apt-get install ?
Thanks.
