You have been subscribed to a public bug: Occasionally when resizing windows on Xubuntu 14.04, the desktop freezes and does not respond to keyboard presses or mouse clicks. When this happens, it is possible to switch to a virtual terminal and execute shell commands. This freeze does not happen everytime a window is resized, but it does happen approximately once per week.
