On my previous system (which I used for about 5 years) I used multiple screens (driven by an NVidia card) to great benefit. My current system (started using about 6 months ago) has a 32" monitor so I no longer feel the need for multiple screens. On some of the industrial (process control) systems I've been responsible for, we put up to 4 monitors (with different displays) driven by one computer in front of a single operator.

I used to use a similar setup years ago on Sun hardware. But as far as I can tell the driver for the Intel integrated graphics doesn't support multiple X screens in that way. The NVidia driver does, but (of course) only for an NVidia graphics card. On the other hand, https://help.ubuntu.com/community/XineramaHowTo has a configuration using xinerama and an intel card, so it may depend on the exact card you have (and I think in that case they're trying to get to a single desktop with multiple monitors, but disabling xinerama mode may get you closer to what you want). It might be easier to buy an NVidia or ATI graphics card (after checking for support)... which is even possible on some laptops. Liam -- Liam R. E.

Liam Thanks Liam, I will see what I can determine from the link you provided. From what I have read about Xinerama it is intended to put multiple screens back together - for example if they are on two discrete video cards - not to break one card into two screens. Still, there is an Intel specific xorg.conf example which I will study. As to purchasing a discrete card... I would certainly do that for a "real" PC or workstation. In fact I just replaced the obsolete Nvidia card which came in my Dell Studio XPS 8000 with a Quadro K420. It runs two 24" monitors separately just fine. The Inspiron 3050s are tiny toys - sort of like the Intel NUC. No room for ANY expansion. However, as they have two monitor connections... sort of a challenge. And considering that most processors Intel makes these days contain graphics... I hate to have to pay more for a Xeon just to avoid the built in graphics - sort of like having to pay for Windoze on a PC I plan to run Linux on :-( Regards, Ken ___ xdg mailing list xdg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xdg

As you know, in X, a "screen" is a pretty central abstraction, with Windows, Pixmaps and other graphics resources all specified in relation to a single "screen". You can't mix-n-match resources between screens, leading to the inability to move windows between them. Over the years, we've substituted that with a similar notion which offers functionality more similar to other window systems, the 'one screen, many monitors' plan as first implemented in PanoramiX (now Xinerama) and then RandR. Here's the differences I can think of between the 'one screen, many monitors' and 'many screens, one monitor each' configurations. If you've got others, I'd love to hear them. One screen, many monitors (Xinerama/RandR): * Move windows among monitors freely * Add/remove monitors on the fly Many screens, one monitor each (core X): * Specify which monitor an application will appear on via the command line (or environment variable). In both: * Resize monitors on the fly * Configure the desktop on each monitor separately * Specify the initial monitor setup in config files. As far as video driver support, the internal server support for multiple "screens" on a single graphics device is twisty, and very few people ever bother to test these setups. It's possible that it will be broken on your favorite card at some point. You can probably understand that supporting both of these models is extra work for all of the developers, and it would be nice if we could make a single model work for most people. -- -keith signature.asc Description: PGP signature ___ xdg mailing list xdg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xdg

Well, I use multiple monitors with single X screen in pretty much the same way - except I can put any of the virtual desktops on any of the monitors. Since you have one portrait and one landscape monitor moving the virtual desktops between the two will probably not be flawless. Still that does not mean you need to configure the X server in such a way it is impossible - you can just not do it. As has been pointed out the Zaphod options should give you multiple X screens but since next to nobody uses these there may be issues. In fact, the very article you linked lists multiple issues when using multiple monitors with separate screens.
