I guess I'm not smart enough to understand the comment above. KDE 1?
You know I'm a Gentoo user and old stuff isn't in portage.

I'm using whatever the stable version from portage is. 4.4.5 I think.

I read through your response, used the Alt-F2 trick to get
systemsettings up and running, didn't see any problems with
KDE-4.4.5's thoughts about what was attached for monitors. It saw one
1280x1024 monitor attached to VGA1 which is what it should see. Still
no panel/taskbar/App Launcher across the bottom. I found I could add
widgets to the desktop but if I tried to add an App Launcher it just
disappeared.

The easy way out was to delete the .kde4 directory in my home
directory and just start like a new user. I'm now back up and
configured the way I want. I don't know what I lost by doing that -
probably some saved passwords, etc., but nothing too hard to set up
again.

Thanks,
Mark
