"The hardware part of our dynamic duo comes from Matrox (http//www.matrox.com), which recently released a graphics board, the Millennium G400, that directly supports two monitors with a single card. The software portion is the dual-head version of Accelerated-X from Xi Graphics (http//www.xig.com), a company that makes several commercial X servers for Linux, Solaris, and FreeBSD."

"Using these products you can get what the fans of multi-head computing call SLS (single logical screen) operation with KDE, GNOME, or any other graphical Linux desktop environment. In an SLS configuration you have one logical screen that just happens to be displayed with the help of more than one physical screen. This means you can grab objects with the mouse and move them from screen to screen, and resize windows and dialogs so they split across physical screens. Your desktop still fully supports virtual desktops, of course, but this way you get two screens per virtual desktop."

"This configuration works quite well with both KDE and GNOME, largely because they don't know it exists. The support for the dual screens is at a low enough level in the systems architecture that it's "below" KDE, GNOME, and your X applications. All they know is that you have a single screen of a given size; they're oblivious to the fact that you're viewing it via two physical monitors."
