Let me see if I can shed a little light on this. I can possibly tell you how to shut things down as well. I use KDE, so your commands may be a bit different.

This is virtual memory, which if I recall correctly includes all of the shared libraries the program references. The actual physical memory for printing is about 7.8 MB on my machine. Certainly it's not the lightest application in the bunch, but it's by far not the biggest. > 2. And, eggcups belongs to my session. I am not familiar with the > terminal concept.

Again, I doubt that you will use an additional 40 MB. However you probably will use an additional 7.8 MB. > 3. If I 'kill nnn', where nnn is the pid of eggcups, it somehow > respawns.

In KDE, the menu entry is under System Settings-->Server Settings-->Services. You'll want to turn off cups, cups-config-daemon, and cups-lpd if it is enabled. In general, you can save memory by eliminating unneeded services, much like you would mark services as manual or disabled under Windows. > 4.

What is gnome-vfs/esd? Are they a must to for a user session? I think gnome-vfs is the Gnome virtual file system. This is probably a must if you're running Gnome (which is the default user interface). esd is the Enlightened Sound Daemon. In addition to providing sound support for other Gnome applications, it also provides sounds for alerts and other system functions. If you want to turn off sound alerts, you can do this in Preferences --> Sound > Please forgive me if my post aroused some kind of holy debate.

As been pointed out by many on the list, your way of asking questions is considered trolling. Here are the reasons. 1. You use a general topic 2. You use inflammatory words (sucks) 3. You've not taken much (if any) time to understand how the Gnome desktop works. 4. Your questions are not questions, but complaints. If you had phrased your query along the following lines, then you might have gotten a better response. I am running Fedora Core 3 as a VM process under a Microsoft Virtual PC. As such, memory is in very short supply. I would like to know how to reduce the memory footprint. a) Can I disable cups? If so, how? b) Can I disable sound? If so, how? c) Can I disable the screen saver? If so, how? d) What other steps can I take to reduce Fedora's memory footprint running in this environment? e) Where can I learn more about 1) The Gnome desktop (which is not the same as Linux or Fedora) 2) Linux in general 3) Programming on Linux (both console and GUI applications) Since some of these answers are easily found via Google, showing that you've at least spent some effort demonstrates good faith. This is an open source environment, and on this list we all contribute freely during our spare time. For example, it's 1:38 AM as I write this. I am writing this because I want to help, and I also want to increase the signal/noise ratio of this mailing list. In return, I want some demonstration from you (the questioner) that you will put at least as much effort into learning about this environment as I have put in writing this message. While I don't expect it, a thank you wouldn't hurt either. ---- /mde/ just my two cents . . . .
