Title:
  After closing and opening the lid on an HP Compaq nc4200 screen is
  turning on and off periodically

Status in “gnome-settings-daemon” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: gnome-settings-daemon

  I am using the final release of Karmic, obtained by switching to
  Karmic already shortly after the Jaunty release and then doing regular
  system updates ("sudo apt-get update; sudo apt-get dist-upgrade") more
  or less once a week.

  The system behaves normally as long as I never close the lid. As soon
  as I close and reopen it, the screen turns black for a second or so
  every 2 or 3 seconds. This stops as soon as I kill gnome-settings-
  daemon. The problem occurs both before logging in, when on the gdm
  screen and after logging in, on the regular GNOME desktop. In both
  cases killing gnome-settings-daemon solves the problem, but many
  features as multimedia keys do not work without gnome-settings-daemon.

  I attach /var/log/syslog. See the lines containing [drm]. They look
  like that the system is going through graphics modes in an infinite
  loop, but on the screen after each darking the screen content returns
  with the same resolution.
