Thread: Different desktop on each monitor

    Ha!

    9 monitors might do the trick. But I wouldn't want to look at my
    electricity bill at the end of my month, heh. The more desktops I have,
    the more I spatially spread out, and 9 seems to be my optimal.

    1. No I haven't seen this feature in any OS but I haven't looked for it
    as much as I have for SuSE. I admit, the average person might not have
    the same type of work behavior as I might, but it was worth a try to
    find out whether this was possible.

    2. Yea, I'm aware of the cube. But I already go left/right/up/down
    through my desktops (using the HJKL keys like vim, so I never leave the
    home row unnecessarily). So I don't see the cube adding anything of
    interest to me.

    3. Clarifications in that use case: D3 has the e-mail and the feedback.
    I switch to [D1 D3] to modify stuff in D1 based on D3. Then I switch to
    [D2 D3] to modify stuff in D2 based on D3. Seriously, this is just the
    simplest example I could come up with to give you an idea of how the
    *mechanism* is supposed to work, but I have multiple ways in mind to use
    this "multiple view" ability.

    One may be worried about being confused, but I really think very
    spatially and this use is very natural to me.

    Have you tried using nvidia-settings and changing the Configuration from
    Twinview to Separate Displays? Click on the Configure... button.

    Yes. Presumably, you mean "Separate X screen". That's the same as the
    multiple X session, and I mentioned the issues with that on my last
    reply to deano_ferrari.

    What you want is I think technically possible, but as far as I know not
    implemented.

    You want a common set of desktops because you are viewing the same set
    of apps. However you want independent views on the desktops. So what you
    need is a desktop manager that is aware of two (or more) screens. I'm
    not sure how that would play out technically with each screen running an
    X server since an app is tied to a server. Maybe the DM would have to
    interpose a virtual server in between, or make it all one large server
    and manage the views itself. AFAIK there is no DM that does this today,
    but I haven't looked in any depth.

    I guess you could call it multiview. It makes sense because multiviews
    sits in between multiscreens and multidesktops.

    Maybe current DMs could do a poor man's version by allowing some apps
    to be sticky in some desktops but not others. Then a virtual desktop
    containing the set of apps you want is a "view" in your scheme.

    Well, the selective-"sticky" doesn't quite have the ability to
    mix-and-match arbitrary desktops at your whim easily, but it's one step
    closer, for sure.

    I think multiview is indeed the perfect word for what I want. The
    actual thing *might* be implementable in the desktop manager itself, but
    I don't know whether there is any way for the X server to indicate
    whether there are multiple views into the same desktop. Perhaps there is
    no need for that if there were implemented as one large virtual desktop
    which was logically separated into two independent views -- a DM could
    probably do that by itself. Anyhoo, if enough people are interested in
    Multiview, I don't see why it won't eventually get implemented.

    I just installed 11.1 on a computer here at work. and it is having the
    same problem that I reported in 11.0.

    'openSUSE 11.0 Dual Desktop problems with KDE 3 and 4 - openSUSE
    Forums' (http://tinyurl.com/b77cxj)

    Dual desktop is not working. The second desk top is a black screen and
    you see the default X pointer when you move the mouse over. The KDE
    desk top is not running on the second monitor. It works on 10.3 which
    is what I am still running on my computer. When 11.0 or 11.1 fix the
    problem then I will upgrade my computer.

    Just seen this post as i'm looking for the same solution. What marcianx
    wants (if the same as me), is the ability to be able to drag and drop a
    document/file/whatever onto the 2nd display and be able to work on that
    screen. I don't want another taskbar or desktop section, just a seperate
    screen from the primary.

    This is easily achieved in windows as it is nativly supported in the
    Nvidia drivers E.G. Having programs running on the 2nd screen whilst
    working on the 1st (like seeing your music/video player on one screen as
    you work on the other).

    In OpenSuse it's possible to configure seperate displays in the Nvidia
    Display Panel, but Sax2 does not allow seperate displays, only
    extended/clone modes. In this case the stumbling block is Sax2 not
    Nvidia.

    Regards

    What you are looking for is a single desktop on dual monitors, done with
    twinview (for Nvidia ) or Xinerama ( X11 ) monitors. Twinview in an
    option in the device section for an Nvidia card. Xinerama tells X11 to
    span the desktop across all monitors configured. I am the only one in
    the Computer lab that I work in that perferes dual desktops. Everyone
    else has single desktop on dual monitors.

    Here is one way to setup an Nvidia card useing Xinerama

    Create a copy the existing device section, add the screen line for each
    device section.

    Section "Device"
    Identifier "Device[0]"
    Driver "nvidia"
    VendorName "NVidia"
    BoardName "GeForce FX 5900 Ultra"
    Screen 0
    EndSection

    Section "Device"
    Identifier "Device[1]"
    Driver "nvidia"
    VendorName "NVidia"
    BoardName "GeForce FX 5900 Ultra"
    Screen 1
    EndSection

    Create a copy of the Screen section. (Below is not the full section)


    Section "Screen"
    Identifier "Screen[0]"
    Device "Device[0]"
    Monitor "Monitor[0]"
    .......
    EndSubSection
    EndSection
    Section "Screen"
    Identifier "Screen[1]"
    Device "Device[1]"
    Monitor "Monitor[0]"
    .......
    EndSubSection
    EndSection

    Here is the server layout.

    Section "ServerLayout"
    Identifier "Layout[all]"
    Screen "Screen[0]" 0 0
    Screen "Screen[1]" RightOf "Screen[0]"
    InputDevice "Keyboard[0]" "CoreKeyboard"
    InputDevice "Mouse[1]" "CorePointer"
    Option "Clone" "off"
    Option "Xinerama" "on"
    EndSection

    We are having problems with dual desktops, two seperate task bars.

    had a "only current screen" option added to it (worked great for me).
    And as a tip:
    Panels on the intersecting side of the screens are a bad idea in 4.2,
    'gives some maximizing issues'
    (https://bugs.kde.org/show_bug.cgi?id=182625). So place them at either
    the 'furthest' sides or the top/bottom.
