Is it a large $HOME/.Xmodmap? Btw. my Ubuntu (not Xubuntu) does use
lightdm and openbox (no DE) and has got no X rc file in $HOME. You
aren't doing something double and triple?

This was @work, meanwhile I am @home and my xubuntu here has a similar
problem: Xorg runs with 100% CPU after login, but after a few minutes it
goes under 1%
The xubuntu @work is constantly running with 99-100% for hours.
