I have a laptop (Dell INSPIRON | 8600) with a LCD. It has worked before,
but since a few months it is going haywire. There are some really
strange interactions between the power cable and the display. It could
be caused by Linux, udev, acpid, xorg, KDE or something else. I have no
Idea. I just want the display to be off after 1 minute of inactivity and
when the lid is closed and then stay off until I touch the keyboard or
pointing device. But that seems to be really difficult to achieve in
Gentoo. For example if the display is off and I connect or disconnect
the power cable, (only) the backlight of the display is turned on. This
behaviour is completely useless and will obviously make the laptop shut
down sooner in the case of a power outage. The backlight must never be
on when the display itself is off. Sometimes when the display should
have been off, it even dares to show some kind of idle animation. It is
a strange looking X at random position and size, on black background. I
have certainly never configured it to do that. Why is it shown? How do I
remove it? Sometimes the display just stays on forever as if it has
completely forgotten that it should shut off after 1 minute. I always
have kcontrol->Peripherals->Display->Power Control open, because
changing a setting, changing it back and pressing Apply fixes the
problem, but only for a little while. I really need to put an end to all
this craziness now!

When I press the lid button I get the following in /var/log/acpid:

When I release it again I get this:

The last number (0000000e when pressed and 0000000f when released) is just a
(hexadecimal) counter that is incremented each time the button is pressed or
released, so on the next press it will be 00000010. I looked what "client
6176[0:0]" could possibly meand and "ps ax|grep 6176" shows /usr/bin/X,
so X is
notified, but it simply does not obey.
In /proc/acpi/button/lid/LID/state the state of the lid button can be
observed
as "state: open" or "state: closed".
