Binary package hint: xorg
Without any obvious trigger, the mouse will cease working. I can still move it, but it doesn't do anything like open tooltips or click, and hovering over the Ubuntu button doesn't cause the launcher to appear. Switching windows via alt+tab or super+w doesn't work either, though otherwise the keyboard input works okay in the window which has focus, and i can bring the launcher up by holding Super, and launch programs using it with the keyboard shortcuts. After i minimize all windows using Super+d, the bring them back, the mouse begins working again for a brief time, until i try alt-tabbing again or clicking outside of the currently-focused window, in which case it reverts to the previous behavior. I've managed to make it go away through some non-repeatable series of minimizing/unminimizing windows and opening the Ubuntu menu over and over again.
The bug only happens to me in Unity in 11.04; it does not happen in the Ubuntu Classic session, and did not happen to me in 10.10.
