Public bug reported:

Binary package hint: xorg

When an external monitor is connected to my Thinkpad T400s using the
Display Port connection, the monitor never goes into an energy saving
state despite the Gnome power saving settings being enabled. Gnome
screen saver activates, but this does not conserve energy of course.

This bug occurs only when the laptop lid is closed. The bug does not
occur when the laptop lid is open.

I have seen this problem with Lucid, Maverick and now the latest daily
build of Natty.

ubuntu-bug xorg crashed, so I don't know if you received the extra
information you need or not. I will include some information here that
might be relevant, just in case:
