      The difference (and this is not a slam towards X - I love it) is that learning a video game is a recreational process. Learning X in a business setting is a productivity issue. In many cases this isn't a big deal, but in some situations this can be a serious consideration.

          This is true, but when you have scores of employees (and let's face it, many of them are not especially bright) you may end up spending the better part of a day teaching them in small or large groups.

      "Basic control over the X desktop" is largely a function of the window manager, not X. And as such, can be as easy or as hard as you want it to be. A WM like icewm takes almost no time to learn for someone coming from windows, while fluxbox is practically unnavigable for someone who hasn't read the docs (but an absolute joy for one who has). The few things that are actually X's responsibility are the middle click text buffer, changing resolutions with CTRL-ALT-+/- and killing the server with CTRL-ALT-BACKSP
    • There is no such thing as an "X desktop", just like there is no such thing as a "GDI+ desktop" or a "PDF desktop". X is a low-level protocol.

      Whether a desktop based on X is easy or difficult to learn depends entirely on the desktop. Something like Ion or CDE, can be frustrating, unintuitive, and complex to novices. OTOH, your local ATM, which may be running X as well, probably is so easy to learn that you don't even think of it as "learning".

    Low level xlib (ie, generic level) support for X session movement from machine to machine.

    This sounds a bit like screen implimented for X - you can take apps to work and back again without shutting them down, and keep apps running whilst restarting an X server. (With a bit of luck it will support echoing one app to mutliple windows as well.) It also allows for graceful app shutdown when an X server dies.

    Up until now I have been using VNC to do this, but adding it directly into xlib should make it a good deal less clunky. Way to go guys.
    • There is a program to do this already - it sets up another X displays, and instead of :0, you use :1. (similar to ssh setting up :10 for tunnelling). It allows programs to be moved from one display to another pretty seamlessly as I recall. It's called 'xmove' I think :-)

      • Xmove while ok in concept, it doesn't work that great in practice. I was able to get it to work on to Xsessions on the same machine, or two VNC Xsessions. But between an Xsession on a remote machine, or even the local Xsession and a local VNC Xsession it wouldn't go due to font and/or color depth incompatibilities.

        Native support that addresses those issues would be great, I would love to run X apps in a screen like wrapper would I could attach them to any Xsession I might be located at.
    • VNC doesn't work at the individual application level; this does. That makes an enormous difference.

      You can get some idea of how this will work in XEmacs (which has multi-display support and can be moved from the console). There is also the xmove server, which already implements this functionality via a proxy.

      It's amazing that this has taken so long. The members of the X Consortium have really been sitting on their hands: this functionality was intended to be in X11 since pretty much the beginning.

    by starseeker ( 141897 ) on Saturday November 22, 2003 @03:47PM (#7537572) Homepage
    A very good overview of the major tools used on Linux desktops.

    I've been wondering about menus in Linux/*BSD - not so much the format of menu storage, although that is an issue, but the applications themselves. We have a very large number of applications out there, but that is a problem for end users because installing them does not result in an update of the graphical menus by which they tend to access them. I think this is one of those little things that makes people think Linux isn't desktop ready.

    I've been wondering - why not do something like the following:

    Create a database of all applications which are or might be deployed on Linux boxes. Define a standard, detailed menu structure into which all these should fit. For example, in the case of science/mathematical applications:

    (Sci/Math)
    (Math)
    (Symbolic)
    (Numerical)
    (Plotting)
    (2D)
    (3D)
    (Electrical)
    (Layout)
    (Simulation)
    (Chemistry)
    (Drawing)
    (Simulating)
    (Physics)
    (Mechanical)
    (Electrical)
    (Quantum)
    (Misc)

    Categories exist mainly as examples - they are not suggestions for what they would actually be. Do the same for graphical applications, editors, programming tools, etc, etc, etc. Once the structure is layed out in broad, start with the Debian archives, freshmeat, sf and savannah, and the other usual suspects and begin defining entries for each application. For each app, there will be a category or categories into which they fit - define this in the entry. To avoid duplicates, assign each category ranking a numerical value - 1 if it definitely should be there, two if it works there but someone wanting a smaller menu structure might not want it, etc. down to don't include this unless a full menu tree is specified. Allow arbitary execution techniques, so apps needing options or odd ways of launching can be accomidated.

    Then, have a way to scan the system binary directories and update based on new binaries found. If the app needs options defined when starting, the entry in the menu will know that and prompt for them when adding it to the active list. Perhaps with some kind of tripwire style system monitoring the menu system could even be triggered as a new binary appears.

    This system would be general and independant, because anybody could write a utility to generate a system's menus based on the database. Then, also, there can be global levels of configuration available. The user could define their own sensitivity - say "Show all Graphics programs but only show level 2 or better text editors". There can even be a "standard" menu structure that doesn't use app names at all, but only generic names and uses the highest ranked app in each category.

    Does anyone know of a project like this underway? I know people have made lists of apps before but if a protocal could be defined to add things like a central database, updating based on binary appearance, user configured options as program is added to menu if desired, etc it might really cause a revolution in Linux desktop menus.
    • The 'menu' package in debian does something along these lines. Frankly I find it messy and filled with stuff I don't want in my menu, so I never use it. :)
    • The problem is that this results in menus that are completely useless and things in all sorts of random places. People think too differently. In case you hadn't noticed, no OS automagically adds things to the menu, the installers for programs do that.

      What Linux needs is decent installation systems. You know, things with options, instead of the usual "Run the RPM and have it fuck up your file associations and menu layout" shit.
      • Well, Debian automagically adds things to the menu, but they have an integrated installer. And frankly, its a bit of a mess. Fortunately there's two menus, the popular tools menu and the "everything installed" submenu. Debian just might be the answer to your RPM problems.

        Of course, then you'll have real problems about installation. Its not very user friendly, but if you can make your way through the text based installers (easy if you're at home with consoles), then day to day operations are simple and most
    • Reason number 3 why Debian rules: Menu system works in concert with the package system itself. (Reason number 1 is APT, reason number 2 is make-kpkg.)

      Debian's menu system is well thought of. A couple of categories (Apps, Games, XShells, and a couple of more), with subcategories. Most menus are kept 2 levels deep, so there's no endless wading through the menus.

      All menu entries are put in menu directories (/usr/lib/menu for packaged apps, /etc/menu for system-wide custom entries, ~/.menu for user-specific

    Reading this document has given me a new respect for the X developers.

    You can use a modern X server to talk to an X client on a 1990s vintage machine with no problems at all, yet X is pretty fast on modern machines, has pretty good 3D support and is being updated to add more and more eye candy all the time - without breaking backwards compatibility.

    Their aims may not be the same as the ones you think they should have for your own use, but when compared against their aims they are doing very well indeed, and should be recognised for that.

    Any X "roadmap" is going to have the hungry trolls out in force, mindlessly flailing around with "arguments" that X is badly designed and should be junked at the first opportunity.

    My take is this. You can do what you like to the underlying graphics subsystem. I neither know nor care what the protocol-on-the-wire says. However, you can take the network transparency from my cold and bloody fingers once I've shuffled off this mortal coil, and even then you'll have a fight on your hands. This single attribute is the reason I use it, and why it's possible to remotely administer far far more unix machines than windows ones. VNC is cool, but X is built-in. I love it.

      VNC doesn't try to address that issue at all. And, in fact, GDI+ and Quartz can be trivially used as remote display engines, but neither their toolkits nor their applications have any clue how to behave properly.

      Unfortunately, Gnome and KDE are eroding network transparency in X11. For example, they use some of their own preferences files, accessed via the file system, which means that preferences come from the remote machine, not the desktop. I think Gnome is trying to address this, I'm not sure about KDE.

    2) A standard way of getting an equivalent to the MSWindows Alt-tab and alt-enter for programs that run in fullscreen mode.

    For example, an extension that the window manager can hook into, that allows fullscreen applications to run in an own workspace, and a xserver enforced keycombination that can bring back the window manager workspaces if the full screen application crashes.

    • There is no need for a standard way of doing it. The xrandr extension allows the possibility of resolution and depth changing on-the-fly.
