I just installed Xubuntu 13.10. I replaced the Desktop directory with a symlink to a directory on another partition (I've been doing this for a while). It worked fine at first, but then I did something that broke the mounting of the partition that Desktop is on. After that, the desktop was showing the contents of the home directory. I fixed the mounting issue and rebooted. I can verify that the target of the Desktop link is properly mounted and there, but the desktop still shows the contents of the home directory. How do I change it back?
(Found this, but it appears to be Gnome-specific.)
