Can't reset Gnome to defaults
After applying the most recent upgrades to Fedora 11 installation, my Gnome desktop became corrupted. The panel at the bottom of the screen is entirely missing, the strip at the top of the screen is only a few pixels wide and has no icons or "clickables", and the window decorations (open/close buttons) are missing. The suspect package was Gnome power manager. Right after the upgrade it reported a configuration error, which I did not save.
I initially tried reinstalling the desktop theme. I have uninstalled the power manager rpm, and removed all of Gnome's configuration-related directories (.gnome, .gnome2, .gconf, .gconfd, and .metacity). I tried creating a new user; that desktop is corrupt as well, so I then went into root's directory and removed the desktop directories from there, thinking that maybe Gnome used them as a skeleton. After seeing no improvement, I reinstalled the gnome desktop environment as a group.
The KDE desktop works ok, but Gnome still does not. I'd appreciate any advice on getting it fixed.
