Samsung NC10-Ecko Plus

Samsung NC10 Ecko plus is NOT the Samsung NC10. This is about Product-Code NP-NC10-JP01DE using Debian squeeze (6.0) and LXDE as the desktop environment.
I started setting up Debian lenny, but found the driver for grafic-card not working, so I dist-upgraded to squeeze and almost everything was perfect. The installation might be different when you start the squeeze installer directly.

Some function keys need a bit adjustment, this is what I did:

Making sound keys work
In LXDE you just have to set the keybindungs. Add the following lines in your ~/.config/openbox/lxde-rc.xml in the keyboard section:

          <keybind key="XF86AudioLowerVolume">
            <action name="Execute">
              <command>amixer -c 0 -- set Master playback 2dB-</command>
            </action>
          </keybind>
          <keybind key="XF86AudioRaiseVolume">
            <action name="Execute">
              <command>amixer -c 0 -- set Master playback 2dB+</command>
            </action>
          </keybind>
          <keybind key="XF86AudioMute">
            <action name="Execute">
              <command>amixer -c 0 -- set Master playback toggle</command>
            </action>
          </keybind>

Making backlight keys work

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>

Switching Blutooth and WLAN

This is done by rfkill and to make it nicer I added osd_cat (from xosd-bin).
The process is the same as above, so I skip the details. Your need two more scripts:

#!/bin/bash
blocked=`rfkill list wlan | grep "Soft blocked: yes"`

if [ -z "$blocked" ]; then
   rfkill block wlan
   echo 'WLAN off'  | osd_cat -p middle -A center -d 1 -f -misc-fixed-bold-r-normal--20-200-75-75-c-120-iso8859-1 -
else
   rfkill unblock wlan
   echo 'WLAN on'  | osd_cat -p middle -A center -d 1 -f -misc-fixed-bold-r-normal--20-200-75-75-c-120-iso8859-1 -
fi

which I called wlan_toggle and put it in /usr/local/sbin.
The next is bluetooth_toggle (also in /usr/local/sbin):

#!/bin/bash
blocked=`rfkill list bluetooth | grep "Soft blocked: yes"`

if [ -z "$blocked" ]; then
   rfkill block bluetooth
   echo 'Bluetooth off'  | osd_cat -p middle -A center -d 1 -f -misc-fixed-bold-r-normal--20-200-75-75-c-120-iso8859-1 -
else
   rfkill unblock bluetooth
   echo 'Bluetooth ein'  | osd_cat -p middle -A center -d 1 -f -misc-fixed-bold-r-normal--20-200-75-75-c-120-iso8859-1 -
fi

Don't forget the sudo settings and then the last step is again the keybinding. For bluetooth I choosed Fn+F8, (don't what the key symbol really means). In LXDE it looks like:

          <keybind key="XF86Launch3">
            <action name="Execute">
              <command>sudo /usr/local/sbin/bluetooth_toggle</command>
            </action>
          </keybind>
          <keybind key="XF86WLAN">
            <action name="Execute">
              <command>sudo /usr/local/sbin/wlan_toggle</command>
            </action>
          </keybind>

Great netbook, it has all I need for a very reasonable price. The time of battery operation is amazing and it runs under Debian Linux.
