When I try to enable KDE's desktop effects the screen goes haywire and everything is black with nasty distorted lines. Then everything returns after a little while and KDE shows a popup notification saying that "desktop effects were too slow and have been suspended...".
I'm pretty sure my xorg.conf is configured perfectly, I've read everything there is to know about that. I was previously on Gnome with Compiz working flawlessly, so I have a feeling its not a video problem. There's always a small chance I could be wrong though.
Could it be a video driver problem? If so, what should I do about that?
Any idea what might be wrong?

Could you give more details about your hardware and which video driver you are using?
Did you read the wiki section about graphical problems in KDE?

I'm using xf86-video-ati with my ATI card.
I initially tried Gnome, but for some reason, gnome-shell just wouldn't start, so that why I ended up trying KDE. Once in KDE, i had this described problem.I couldn't fix it, and it was crashing (100% CPU usage sometimes), so I switched back to Gnome 3 to attempt to get the shell running. Finally, I figured out that you must not add "nomodeset" to the kernel boot line in order for gnome-shell to work, so I removed that from the end of my line and gnome-shell worked!
It might be possible that this is the solution for the KDE graphic problem as well... I'm testing it right now, i'll be back to post it after the restart...

Confirmed, removing nomodeset from the kernel boot line enabled KDE desktop effects.
