Hello,
I was playing with the xinitrc's (I was running KDE), accidently I click the xinitrc in the /etc/X11/XFCE4 folder, and without knowing what's going to happen, I was stupid enough to click yes when a pop-up window ask me if I'm sure I want to run the script.

The result is that now I have XFCE4 running together with KDE. The desktop is KDE, but there's the XFCE4 panel floating on it. I checked to see if my xinitrc in my local folder has changed, but it didn't. I tried to restart the system, but the floating panel still there.

This is really annoying, can somebody please help me get rid of it? Thanks a lot.
