Where's my free "Desktop Panel?"

view full story

http://forums.fedoraforum.org – I've done three Fedora 12 installs recently. Two were from the complete DVD . . . generic and KDE versions. In both cases, KDE desktop was by default graced with nice translucent panel where the icons for Firefox & etc. could frolic and play and exhibit single-click behavior. The third system started out as a Vista laptop that got a rootkit. Booted to a Live CD, backed up my data, did an install. It took a bit to get all the required KDE packages installed, but even so I didn't get that desktop panel. I found the "add panel" control, and I can add widgets to it, but I can't figure out how to recreate that desktop panel. Any help appreciated. (HowTos)
