I enabled desktop effects in KDE/Gnome - now unusable - bug or driver?

As the title suggests, I am rather new to Linux and just installed Fedora 10. While "tweaking" the desktop settings, I decided to enable several visuals for the windows (animations, shading, etc.), and now I have a screen full of black and grey boxes corresponding to the windows that were there, but KDE is now unusable as I can't see anything.

I thought a box popped up when I selected "apply" that said the settings would revert after a period of time if I didn't click okay, but apparently it didn't work.

Is there a way that I can reset the desktop to the default settings? I would assume that I'll need to log in as root and delete some things with an editor? Can I do this from Gnome?

I couldn't find anything similar when I searched.

my method was

log in with gnome and create a new user and use this one instead. Move you files there and change ownership to the new user. Then delete the old user.

Maybe there are some better ways. But one known working way is better than 100 better ones if they are unknown.

More info

After deleting/recreating account several times, here's what I've found -

If I enable desktop effects (default) in Gnome I get a white screen, no mouse. Pressing control-alt-delete gets me to the log off screen, if I cancel I get to the desktop effects window that I can close and all is good.

If I enable in KDE (default options), I get a black screen with a mouse, only option is to control-alt-delete, log off, log in under different user and delete/recreate my account.

Bug or driver issue? Fresh install of Fedora 10 with no updates.

Gateway GT5648E (got it cheaper than building my own this Spring)
Vista Home Premium SP1/Fedora 10
AMD Athlon 64 X2 Dual Core 6000+

TSSTcorp CD/DVDW TS-H652D (Samsung?)
NVIDIA® GeForce® 6150SE (on MOBO)
320gb Seagate Barracuda 7200 ST3320820AS SATAII

Drive is currently 10 gig recovery, 258 gig for Vista, and 29 gig Linux.

Smile and without those effects?

well I don' t use at all those desktop-effects. Are the so important in fact? I heard I had to install the proprietary nvidia-driver to use the desktop-effects. So I declinded.

I also had that problem on KDE4+Fedora10. I got a black screen and "shadows" of windows and menus.
On Gnome, when I tried to enable effects I had a message informing that it was impossible to enable them.
I solved the problem on KDE by logging in to Gnome and deleting the directory .kde4 in my home dir.

You don't generally have to be as drastic as killing the whole .kde configuration directory.

Start by logging in as another user and becoming the super user (or login as root if you've enabled that) or go to a console window Ctrl-Alt-F2 login and login as yourself. Edit your /home/myloginname/.kde/share/config/kwinrc file.

Remove the Effects sections and Compositing sections for a start. You may, at times, need to eliminate the plasmarc file completely as well.

Then restart as normal. If all else fails-you simply can't use any text based editor, you are running a login manager that won't let you log in as root (Stupid Fedora design decisions!) then just delete kwinrc.

When you log in again as your normal old self, the defaults will be picked for the settings that are missing or the files will be recreated. If you can't login as root from the GUI, I suggest fixing that ASAP. Don't login as root unless it's an emergency, but this qualifies, and not being able to do it to fix situations like this is silly.
