Title:
  periodic compiz freezes with no logs or error messages, requires me to
  kill compiz

Status in compiz package in Ubuntu:
  Invalid

Bug description:
  To start, unfortunately, I have no idea how to reproduce this, nor how
  to trigger it.  All I know is that occasionally I will go away and
  come back hours later to discover that compiz is locked up tight.

  What I see when this happens is the lock screen (screen locks when the
  screensaver engages or screen blanks).  I can still get mouse cursor
  movements which is enough to trigger the monitor to turn back on, BUT
  the password entry box is FULL of dots and while I can move the
  pointer around, clicks are not registered anywhere, nor is any
  keypress.

  When this happens, I can restore the session by sshing into the
  system, and killing the compiz process which I always find consuming
  between 96 and 99% CPU and hung.  Once I kill compiz, it reloads and I
  am able to get back into the system and continue on.

  This happens at least once a week, it seems and I have no idea what
  triggers it as the system is always left idle when it occurs.

  System is an Alienware M15x with an nVidia GT240M card using the
  proprietary nVidia drivers.
