I just installed Gusty and I'm also experiencing exactly the same problem as MichaelElkins described above, but on a Dell D810 (with radeon card too). Ctrl-Alt-BackSpace doesn't work for me either, but Alt-SysRq-b does "work". It happens so often that there's no way to do any work with that enabled (why is it on by default I don't know), so I turned it off. I tried using the proprietary ATI driver to see if it has the same problem, but then I would just get a message saying the composite extension isn't available. Conclusion, desktop effects not usable on this laptop in any way.
