** Description changed:

  Binary package hint: xorg
  
  If I don't use the computer for a while, the monitor goes to standby to
  save power. When I later come back I get the login screen because the
  previously running session is crashed. However, this is not
  reproducible, it seems to happen randomly since upgrading to Lucid.
