Hi,
a. ACER/ASPIRE 1810T
b. openSUSE version: 11.4 ( 2.6.37.6-0.7-desktop #1 SMP PREEMPT 2011-07-21 02:17:24 +0200 i686 i686 i386 GNU/Linux )
c. I use the laptop on my desk with AC Power and external Display Samsung SyncMaster P2770 connected on HDMI1
Powermanagement Profile contains only AC Profile with the option “Do nothing if laptop lid is closed”
If i close my laptop lid the external Display is switched off/gets black
How to prevent that behaviour?
Why the system cant do nothing in conjunction with display devices?
I love to use this great little xrandr prog myself, like this simple code
#!/bin/sh
if $(xrandr | grep -e "^HDMI1\ connected") == HDMI1* ]]
then xrandr --output LVDS1 --off --output HDMI1 --auto
else xrandr --output LVDS1 --auto --output HDMI1 --off
fi
which helps me to switch off the internal display automatically at startup only if the external display at HDMI1 is connected.
I am thankful for any suggestion.

you might try using YaST to install laptop-mode-tools and
patterns-openSUSE-laptop…
well, you don’t mention what desktop environment you have so i can’t
tell if maybe you need patterns-openSUSE-kde4_laptop or
patterns-openSUSE-lxde_laptop or neither…
i say try and maybe because i really don’t know what will help and
what won’t…

Thanks for that.
laptop-mode-tools wasn´t installed yet. But pattern-openSUSE-laptop & pattern-openSUSE-kde4-laptop is installed allready.
You are right i followed the sticky note but there was no hint for desktop environment.
But i can remember the default or preselected desktop environment for openSUSE is kde4 and that is nice!
I will try. But I am a little bit confused why the pattern-openSUSE-laptop has no dependency to laptop-mode-tools.
For me that seems to be a hint that developers wanted to separate it for the end user with a reason, at least it should have a reason.
–edit–
It seems that i found the reason, because laptop-mode-tools pulls in PolicyKit and hal.
hal itself pulls in gimp-module-hal and gstreamer-0_10-plugin-hal.
I will cancel that software install and try to figure out more about my problem.

if you need more help, please declare if you elected the default, or
something else…it usually makes a difference in how the answer is
crafted…

Hm forgot to declare again! 
I selected the default kde4 desktop.
I found a possible solution for my problem:
system settings -> Startup and Shutdown -> Service Manager -> Startup Services
I unchecked Display Management change monitor and stopped it too.
Now i can close the lid and open it without changes to the display setting.
