If enable dual head mode (two X screens) on Ubuntu 11.10, there is no window manager after login (no window decoration, cannot move/resize window, cursor shown as "X" instead of arrow, ...). And the unity launcher and panel doesn't show on second screen either.

There is another problem for nautilus in this dual head configuration.
