Desktop icons vanished!
 

In trying to set a "fixed" IP address for the Linux machine on the network (unsuccessfully), I have managed to make all my desktop icons disappear.

I saw a screen which talked about KDE resource allocation - I'm not sure how I got to it, and I can't find it again. I closed it, and the icons disappeared from the desktop and the desktop picture started flashing on and off at about 2 second intervals.

The desktop icons are still in their folder (/home/keithj/Desktop) but I can't get them to reappear. I can run stuff from the taskbar, but that's a pain compared with having all the stuff I use on the desktop.

Can anyone tell me what I've done, and how to fix it?

I'm running "installed" Knoppix, which I think is Debian, on a Coppermine 600MHz.

Control Panel/Desktop/Behavior/Show icons on desktops.
or
right-click on desktop/Configure Desktop/Behavior/Show...

Thanks - in the end, it wasn't that. The "Desktop theme" had disappeared, and apparently without that there is a desktop with a picture but it can't have icons on it. I reinstalled the theme, and the icons reappeared. All solved.
