I remember buying a Matrox dual-head used around 2003 and being incredibly excited putting it into a frankentower alongside the integrated graphics and an old VGA card, giving me two "high resolution" monitors and two peripheral ones: https://www.jefftk.com/college-multihead-linux.jpg https://www.jefftk.com/college-multihead-linux.jpg The card wasn't well supported by Gentoo, and every time I rebuilt the kernel, which was surprisingly often, there was an awkward manual step involving copying over something for the HAL.
