Hallo, ich habe das oben genannte Netbook ,jedoch funktioniert dort nicht alles und vorallem die Bildschirmhelligkeit kann ich nicht ändern. In diesem Forum gab es kaum Hilfe dafür deshalb habe ich woanders diese Hilfe gefunden nur habe ich von Linux zu wenig Erfahrung um diese einstellungen richtig vorzunehmen. Ich hoffe ihr könnt mir auf einfache weise erklären wo und wie ich das umstellen kann. Ich kopiere hier jetzt den nötigen Text und stelle auch die Quelle(den Link) ein. Ich Danke euch schonmal für eure Mühe. http://www.linlap.com/wiki/samsung+nc10+ecko+plus

This is bit more work. Unfortunatley xbacklight does not work, so you have to set the pci-parameters directly. Thanks to archlinux, there is a script to do so. Just put the following in your /usr/local/sbin:
#!/bin/bash
# increase/decrease/set/get the backlight brightness (range 0-255)
#
# PCI device on which to operate
DEVICE=00:02.0
# Amount to raise/lower the backlight when called with "up" or "down"
AMOUNT=10
# Minimum backlight value reachable via "down"
MIN=20
# Default backlight level when toggling on (HEX value!)
DEFAULT=80
#get current brightness in hex and convert to decimal
var1=`setpci -s $DEVICE F4.B`
var1d=$((0x$var1))
case "$1" in
up)
#calculate new brightness
var2=`echo "ibase=10; obase=16; a=($var1d+$AMOUNT);if (a<255) print a else print 255" | bc`
echo "$0: increasing brightness from $((0x$var1)) to $((0x$var2))"
setpci -s $DEVICE F4.B=$var2
;;
down)
#calculate new brightness
var2=`echo "ibase=10; obase=16; a=($var1d-$AMOUNT);if (a>$MIN) print a else print $MIN" | bc`
echo "$0: decreasing brightness from $((0x$var1)) to $((0x$var2))"
setpci -s $DEVICE F4.B=$var2
;;
set)
var2=`echo "ibase=10; obase=16; a=$2;if (a>$MIN) print a else print $MIN" | bc`
echo "$0: setting brightness to $((0x$var2))"
setpci -s $DEVICE F4.B=$var2
;;
get)
echo "$0: current brightness is $var1d"
;;
toggle)
if [ $var1d -eq 0 ] ; then
echo "toggling up"
setpci -s $DEVICE F4.B=$DEFAULT
else
echo "toggling down"
setpci -s $DEVICE F4.B=0
fi
;;
*)
echo "usage: $0 {up|down|set <val>|get|toggle}"
;;
esac
exit 0

The script should be
-rwx------ 1 root root
Then allow your user to execute is as root (as it uses setpci) by visudo and adding the line:
name_of_the_user ALL=(root) NOPASSWD: /usr/local/sbin/backlight_samsung
(I called the script backlight_samsung)
And finally add the keybindungs. In LXDE it is by adding the following lines to your ~/.config/openbox/lxde-rc.xml (keyboard section):
<keybind key="XF86MonBrightnessUp">
<action name="Execute">
<command>sudo /usr/local/sbin/backlight_samsung up</command>
</action>
</keybind>
<keybind key="XF86MonBrightnessDown">
<action name="Execute">
<command>sudo /usr/local/sbin/backlight_samsung down</command>
</action>
</keybind>
<keybind key="XF86Launch1">
<action name="Execute">
<command>sudo /usr/local/sbin/backlight_samsung toggle</command>
</action>
</keybind>
