Having multiple screens only limits what you can do and gives you no meaningful benefits. 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. Multiple heads/outputs/monitors do not have to imply multiple X11 'screens'. They can, but they don't have to, and it's very rare to prefer multiple screens. 'Screen' is a jargon term in this context, like 'display' - I'm putting it in quotes to be unambiguous. If all your applications run with DISPLAY=:0, or equivalently DISPLAY=:0.0, you have one X11 'screen', potentially outputting to multiple monitors. If some of your applications run with DISPLAY=:0.1 and are permanently tied to a different set of monitors (probably a set of size 1), *that* is a second X11 'screen'. If you have multiple LCD/CRT/whatever monitors on one desk, or a laptop and a monitor, or a laptop and a projector, the option that is usually preferred is a single X11 'screen' spanning multiple monitors, with optional runtime switching between mirroring (same content on each output) and non-mirroring (different content on each output). That's what Xrandr normally does on modern systems, and as far as I'm aware, what all current desktop environments optimize for. It's also the X11 equivalent of all the supported arrangements in Windows and OS X. For instance, on the laptop where I'm typing this (with Intel HD graphics, as it happens), here's what my output looks like: |--| | monitor ||| | || laptop | |--||| DISPLAY :0 --- screen :0.0 /-- HDMI2 --- monitor \-- LVDS1 --- laptop The equivalent with multiple 'screens': DISPLAY :0 /-- screen :0.0 --- HDMI2 --- monitor \-- screen :0.1 --- LVDS1 --- laptop would mean I wouldn't be able to drag windows to and from the laptop, or copy and paste between the two screens, and I don't have enough historical X11 knowledge to know whether I'd need a second keyboard and mouse for that setup. I have to admit that the Linux / X window (and successor) terminology confurses me--when I say multiple screens, I mean multiple monitors driven by a single PC and different content on each, and, ideally (but not always the case) the ability to move content between displays and copy and paste to and from each. It sounds as though rhkramer may be one of the people Michal is thinking of, who has been confused by the unfortunate historical terminology, does want multiple monitors, but does not necessarily want multiple of the historical X11 construct whose jargon term is 'screen'. I appreciate the vote of confidence. Perhaps "separate X screens" is something which only a small percentage of user are multi-tasking enough to take advantage of. However, I am one of them. From other emails, it sounds as though you (for disambiguation: Ken) are one of the minority that genuinely does want multiple X11 'screens', with no copy/paste between them, and no ability to move windows between them. I'm not sure how this actually improves your experience when multi-tasking when compared with a Xrandr-style large 'screen' spanning multiple monitors, but "you asked for it/you got it"[1]. However, this is a sufficiently small minority that it seems reasonable to ask "are you *sure* this is really what you're looking for?" when someone asks for it, because it's fairly common for people who are confused by the terminology to think they want multiple (jargon) 'screens' for their multiple (non-jargon) screens, even though that leads to reduced functionality. If your goal is to have immovable displays appearing on particular monitors, that's also possible to achieve within a single 'screen' by modifying or configuring a window manager or compositor to place windows where you want them. (For instance, tiling window managers like Awesome[2] tend to support this sort of thing.) Thanks Simon, I don't think this is really as complicated as you make it appear. If you will look at the last option on this page http://jsmylinux.no-ip.org/basic-information/dual-monitors/ titled "Individual Panels" that is what I setup on my Nvidia card when I first got the PC and two monitors in 2009 (Ubuntu 9.10).

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.

Please see this page: http://jsmylinux.no-ip.org/basic-information/dual-monitors/ and have a look towards the bottom titled "Individual Panels". It seems to me a reasonable thing to want. 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 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
