** Description changed:

  Binary package hint: xorg
  
  Since I've activated KDE SC 4.4's compositing, my X server crashes every
  couple of days. No advance warning, no apparent ill effects apart from
  having to log back in and redo every piece of work that wasn't saved.
  The screen goes blank, then switches to whatever tty was active before.
  Any sound output keeps playing for a couple of seconds (3-5) and the
  just stops. After I've logged back in, it takes another couple of days
  before the crash reoccurs.
  
  The crash trace is in the .old log near the end.
