Crunchbang on the Samsung NC10

Those of you who are running Crunchbang on a Samsung NC10 may have noticed that while it is blazing fast, there are a few tweaks that need to be made to get it completely up to speed. I'll share the links to tweaks I've used here, and hopefully it will be beneficial to others, and people will add to it.

1a. Audio Jack - You may have noticed that plugging headphones or outside speakers in the headphone jack doesn't mute the laptop's speakers. Fortunately, there is a fix for this. *Note - This WILL break your wireless, but there's an easy fix for that too, which is outlined in Tip #1b.

https://help.ubuntu.com/community/NC10# … a%20Driver

1b. Bringing your Wireless back to life - Now that your audio works, you can watch YouTube videos without disturbing everyone in the coffee shop. Or could if your wireless wasn't broken. But we can install the ath5k madwifi driver, not the one that comes with the initial Ubuntu kernel. *Note - If you only have wireless access (can't plug into the network cable), then do this 1st and the audio fix 2nd.

http://nc10linux.wordpress.com/2008/12/ … rformance/ This works with the current developmental driver - compat-wireless-2009-03-11.tar.bz2, and contrary to what the post says, you don't already have to have another version of the ath5k madwifi driver installed.

2. Working Audio Fn Keys - Now that you have normal audio and working wireless, you will want to be able to control that audio. So add this to the bottom of the keybind section of your rc.xml file, and your Fn+left/right arrow keys will work, just like they are supposed to!

<keybind key="XF86AudioLowerVolume">
    <action name="Execute">
        <execute>amixer -c 0 set Master unmute</execute>
    </action>
    <action name="Execute">
        <execute>amixer -c 0 set Master 2dB-</execute>
    </action>
    </keybind>
<keybind key="XF86AudioRaiseVolume">
    <action name="Execute">
        <execute>amixer -c 0 set Master unmute</execute>
    </action>
    <action name="Execute">
        <execute>amixer -c 0 set Master 2dB+</execute>
    </action>
    </keybind>

To get your mute key working (Alt-F6), add these lines to your rc.xml: (Thanks to SpandexBob for this)

       <keybind key="XF86AudioMute">
      <action name="Execute">
        <execute>amixer -c 0 set Master mute</execute>
      </action>
          <action name="Execute">
        <execute>amixer -c 0 set Master unmute</execute>
    </action>
    </keybind>

3. Screen Brightness - Currently, the Fn Brightness keys do not work, (the key combination when run through Xev shows no output, so it's not a matter of mapping them correctly in your rc.xml). There is, however, a workaround, by mapping the key combination to the Ctrl Key instead. First, install xbacklight:

sudo apt get install xbacklight

Then add these lines to your rc.xml:

    <keybind key="C-Up">
      <action name="Execute">
        <execute>xbacklight -inc 10</execute>
      </action>
    </keybind>
        <keybind key="C-Down">
      <action name="Execute">
        <execute>xbacklight -dec 10</execute>
      </action>
    </keybind>

on restart, you should be able to control your screen brightness.

More fixes will show up as they get fixed. Hope this helps
