Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

When I tried to enable translucency/shadows, I got this message:
"Composite extension not found
You must use XOrg ? 6.8 for translucency and shadows to work.
Additionally, you need to add a new section to your X config file:
Option "Composite" "Enable"
I'm using Xorg as my graphics server (radeon flgrfx), or at least I think I am.
I think I have Xorg 6.8, becuse I have KDE 3.4 installed.
Where is the X config file? Have I done everything necessary before I edit the file?
Well you need to find out if you do indeed have xorg 6.8. I'm pretty new so I'm not sure what the best command is to find out, if you are on debian you could do" apt-cache show xserver-xorg" and that would at least tell you what version is installed.
Then you can go here for how to enable the transparency/shadow - down the page a bit http://baghira.sourceforge.net/xcompmgr.htm

That's strange, I was actually suprised at how good it was.
I only have a 1200 cpu and 512mb ram and I don't even know what graphics card I have but I'm certain it's nothing fancy.
KDE3.4 runs a bit slow but just using shadows I reckon it's pretty much the same as using windowfx on windows, speed wise.
On gnome 2.10 and xfce4.2 I'm not noticing any slowdown at all.
[EDIT] I should point out that when I said kde was running a bit slow, the windows are moving around fine and min/maxing quickly but most apps are taking ages to start up.
I've been running kde for a couple of hours without any shadows or transparency and apps are still taking ages to load. What distro are you using kde on? I've been using the one from ubuntu on debian unstable and I'm very unimpressed, I'm now in the process of downgrading back to my old version to see how that runs.

I've got slightly better hardware with an Nvidia card and I can use the composite extension without any noticable slowdowns. ATi just seems to have crappy linux performance all-round which sucks because they're a really good graphics card with the right drivers (ie: Windows )

You seem to be on the right track.
I just messed around a bit with the drivers offered by Xorg, and chose "ati" instead of "radeon." Go figure. Probably works because it is more generic, but that's just a guess. Peformance is now very fast, but still with some artifacting onscreen when resizing windows. Getting closer though . . . .
Yes, ATI cards on WinXP are sweet. KDE will improve its support, though, as we go through newer and better versions.
Interestingly, my machine (freshly installed Fedora Core 4 on Athlon 64 3500+, GeForce 6800 GT...you'd think it would handle transparency) CANNOT at all display a coherent screen with transparency on. It's possible that I don't have OpenGL enabled, if that even makes a difference, but I honestly can't tell (as a sidenote, does anyone know where I can enable OpenGL in Fedora Core 4? I can't seem to find that setting...). Either way once I apply the transparency settings my screen basically splits in two and freaks out, showing phantom images of random windows all over the place. Once I turn off the transparency, it immediately fixes itself. Needless to say I've decided it's not worth it for now.
