How did you make it work? I'm running FC1 updated with KDE 3.2. I downloaded Xpde ran the install script as root and the setup script as a regular user. Then I changed the file initrcDEFAULT in the regular user's home directory to ./initrc and restarted X. I still get my KDE desktop and Xpde is not in the list of desktops I can load.
Any suggestions?
