Title:
  Major security issue with light-locker - console switching gives
  access to other screens for a few seconds

Status in light-locker package in Ubuntu:
  Incomplete
Status in lightdm package in Ubuntu:
  Invalid

Bug description:
  light-locker is completely insecure for X configurations with multiple
  screens that are not using a single display.

  My setup - 4 monitors, nvidia, each with separate screen.

  If I lock screen and then control-alt-f7 back to X, only one single
  screen is protected. After several seconds, it forces a switch to the
  lock display, but in the mean time, the other three screens are
  COMPLETELY UNPROTECTED.

  It only takes a few seconds to launch a terminal and killall light-
  locker and I have unrestricted access to all.
