While they are not eating cpu time, I am curious why a user who has logged in (switch user in Cinnamon) and then logged out with the orginal user logging back in (actually never logged out, so just entering password to get back) has 21 processes running. The processes have something to do with the windowing system, but geez that seems like a lot after cleanup and logout. Is this a "feature" of X windows or Cinnamon or ??
