Actually, the bug can be rewritten in a much simpler way.

xset dpms force off does *not* work on my laptop's screen. If I plug in
an external screen, and disable the laptop's screen, xset dpms force off
actually turns off the external screen. If I enable the laptop's screen,
it prevents both screens from turning off. With no external monitor, it
doesn't work of course.

jonathan@nala:~ $ uname -a
Linux nala 2.6.32.2 #1 SMP Mon Dec 21 15:44:54 CET 2009 i686 GNU/Linux

Bug still present. I'm on testing, and I don't see a 2.6.32-8 package in
the repositories. Do you want me to install linux-image-2.6.32-trunk ?

against it.

Sorry for the delay, I'm busy with other projects.

Just ran a test against latest 2.6.32-5 from testing and xset dpms force
off still doesn't work for the LVDS screen.
