Title:
  gnome-screensaver is constantly wasting CPU

Status in “gnome-screensaver” package in Ubuntu:
  Incomplete

Bug description:
  I keep noticing that my computer is unusually hot; running "top" shows
  that gnome-screensaver is the culprit:

    PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND                                                                                                                  
  18746 xbmc      20   0  236m 4420 2556 R   99  0.2  11978:58 gnome-screensav 
   1923 xbmc      20   0  627m  64m  15m S   14  3.7   4109:52 compiz

  That's eight days of CPU time! That can't possibly be good for the
  hardware, and it certainly doesn't help the overall performance of the
  system.
