I have Apple's X11 and KDE 3.1 running AWESOME on my tibook.
i'll just do a quick walkthrough of how to do this from the first block.
get rid of XDarwin. it's a nasty bitch to get to run with apple's X11, though it can be done, i am told. then get apple's x11 and the SDK from their site.
after that's done, gotta grab fink. follow
these instructions. don't get fink commander though, i think it's much more of an immersive experience to gird up your loins and jump into the terminal.
open a new terminal window. type:
sudo apt-get bundle-kde
this will download the latest stable release of KDE.
after you do this, you'll want to make a .xinitrc file to start KDE when you open X11.
in terminal, hit
pico ~/.xinitrc
you'll get a pretty, empty box in which to enter text. enter:
source /sw/bin/init.sh
/sw/bin/startkde
save this by hitting ctrl+x and responding in the affirmitive to saving it.
now, you can open up X11 and KDE should start. you may have to wait a good while. when you get it all set up, if there is a background dominating your desktop so you can't see your mac desktop, you can click on the start applications button, go to settings, then open control panel. there, you can go to the "desktop" tab, and select the "behavior" subtab. here, you can turn off the "enable desktop icons." you can adjust the panel on the bottom by right clicking it and selecting "configure panel." this will let you put it on the top, bottom, right, and so on. play with it till you get it out of the way of the dock.
KDE is highly customizable. go to
www.kde-look.org if you want to theme it. it's a little complicated to figure out, but you can email me with any specific questions if you want. i wouldn't pretend to know it all, but i manage to get around. i learned it all by playing around recklessly, and RTFM, of course
here is my desktop with KDE up:
