    Re: Making sense of Linux/Ubuntu desktop systems

    OK, closing in on this. Just a few comments to keep it simple.

    GTK (Gnu toolkit -- or Gnome toolkit?) is a programming toolkit. You'll never need to use it or install it, and ordinarily you don't need to be concerned with it. If you are told that a program is built with gtk or qt, however, that describes how the program looks.

    Gnome version 2 has been replaced in most distributions with Gnome version 3, or "Gnome 3". The Gnome Shell runs on top of Gnome 3, and it essentially gives you the panel or bar that you use to run the computer. Unity is Ubuntu's alternative, and is somewhat similar.

    Oh--and very important. If you don't like Unity, you can install gnome-fallback or something (varies by version) and select Gnome Classic without effects at the login page.

    Just to make it even more complicated, Compiz has been largely replaced, I think by something called "Mutter". And X11 will be going away, to be replaced by either of two replacements.

    Simple, no?

    It also tells you what dependencies it will likely use (Gnome vs KDE). More info on GTK if anyone is interested can be found on their website.

    OK, some more explanation.

    Fortunately, with Linux you don't have to worry about dependencies, because they are handled automatically. ("Dependencies is a funny computerese way of specifying what components are required to run a program.)

    Most programs come in one of two different types -- Gnome or KDE (Gnome uses GTK; KDE uses QT, but you don't have to write that down). The two types look a little different and the menus, etc. may act a little different. (Remember that KDE is a different desktop and looks different from Gnome.)

    Ubuntu comes with Gnome programs, but don't let that stop you. Some of the best programs are KDE programs. If you want to install and use a KDE program (example: K3b), go right ahead. The first KDE program you install will cause a little extra stuff to be installed (not much, really), but that is ordinarily not any problem at all unless you are extremely low on disk space. It won't make any difference in the way your computer runs, and you might not even notice anything different about the KDE program.

    Linux is simply made up of frameworks. It takes 10 years to understand how the frameworks work together. And by that time, the frameworks will change.

    Thanks

    Bunch of framesworks and libraries, each doing their part.

    What the heck am I using in Ubuntu? All? What role does every one of those serve? I'm trying to make sense of all these terms and how the windowing system is built up.
    As a programmer, you seem to know very little about GNU/Linux. I am just a "stupid" Linux user, I know zilch about programming, hacking, compiling, you name it , and I seem to know more than you (I don't mean this in a bad way). You should start reading up about the "parts" of Linux.

    The answers to the OP's questions are going to come from developer resources and (gasp!) books, not from a user forum.

    Apple maintains considerable online resources explaining the OS X stack, for an alernative approach.

    The use of Windows as the standard for goodness and beauty in software is,of course, incorrect.

    Unless you wanted to run a Unix system. In that case, Slackware was very useful, whie DOS/Windows was a waste of time and money.

    Indeed. I was buiilding routers and servers in 1996, first on Slack and later on RedHat (RPM was an enormous step forward). I guess my clients who were using these "useless" machines must have been deluded.
    If you ask for help, please have the courtesy to check for responses and thank the people who helped you.
