Comment 17 for bug 329616

I had the same problem, and used the workaround. After some time, the problem came back. I now get ~6 instances of xfdesktop at startup. I attached the xfce4-verbose log to this post.

I'll leave the system 'as is' for some time ( using num=`ps x | grep 'xfdesktop' | wc | cut -c 4-8`; num=$(( ${num} - 2 )); for process in `ps x | grep 'xfdesktop' | cut -c -5 | head -${num}`; do; kill $process; done as "workaround" for now), so if some developer needs some tests done - feel welcome to ask.
