    Does anybody know the command line that will 'refresh' the battery monitor to make it show the right status?

    I would love to know this as well. I'm a new Samsung Series 9 NP900X4C-A01US owner and I am experiencing the same issues:

    1) Battery status doesn't update properly, mainly when pulling the power plug.
    2) Closing the lid doesn't suspend even though the setting is set to.

    I'm running Ubuntu 12.10 (up to date as of today).

    For people with the touchpad problems (pressure sensitivity, 2-finger scrolling, etc), I found this page while searching the issue (some of the previous posts/links didn't have anything to do with pressure sensitivity):

    https://gist.github.com/2382480

    So far it seems to be working out for me. I simply put in the following into /usr/share/X11/xorg.conf.d/52-np900x4c-clickpad.conf and rebooted.

    Code:
    Section "InputClass"
      Identifier      "np900x4c clickpad"
      MatchIsTouchpad "on"
      Driver          "synaptics"
    
      # Enable the clickpad and set click actions
      Option "ClickPad"      "1"
      Option "ClickFinger1"  "1"
      Option "ClickFinger2"  "1"
      Option "ClickFinger3"  "1"
      Option "SoftButtonAreas" "1950 0 1900 0 0 0 0 0"
      Option "TapAndDragGesture" "0"
    
      # Pressure required to move the cursor
      Option "FingerHigh" "15"
      Option "FingerLow"  "15"
    
      # Allow a bit of error before the cursor moves.
      Option "HorizHysteresis" "17"
      Option "VertHysteresis" "17"
    
      # Mouse speed
      Option "MinSpeed" "1"
      Option "MaxSpeed" "5"
      Option "AccelFactor" "0.05"
    
      # Two Finger scroll speed
      Option "VertScrollDelta" "30"
      Option "HorizScrollDelta" "30"
    
      # Enable palm detection and set palm senstitivity
      Option "PalmDetect"    "1"
      Option "PalmMinWidth"  "5"
      Option "PalmMinZ"      "40"
    EndSection

    Re: Samsung series 9

    Just got my NP900X4C set up with 12.04, and everything seems to be working alright, I added the "Linux on my samsung" PPA, as well as installed the packages to fix the backlight etc. The keyboard backlight is perminantly off though, does anyone know a fix to at least turn it on? From reading the forums, is seems that the kernel for 12.10 will allow they keys to function, but it would be really sweet if there were some way to get it to light up before october when 12.10 ships.


    Other than that, this laptop is awesome, great (9ish hours) battery life, and its fast as hell. This thread has been super helpful so far

    Quick question for owners of the 900X3C/X4C: can you make Caps Lock an aditional Ctrl?

    Settings > Keyboard Layout > Layouts > Options ... > Ctrl key position > Caps Lock as Ctrl (or 'Swap Ctrl and Caps Lock')

    There are a few keyboards where this isn't possible.

    Hi

    Bought NP900X3C and cannot get any decent battery life

    All my powertop tunables are in order but it appears that the wakeups for "PS2 mouse" are too high (around 300 interrupts a second). If I disable the ps2 mouse module then my battery consumption in powertop quotes me around 7 hours.

    Does anyone have issues with the trackpad reducing battery life? I have used the touchpad configuration from the Ubuntu Samsung Series 9 wiki.

    I've got problem with Bluetooth headset Nokia BH-214 & Samsung 900X3. Laptop paired with device and OS (Ubuntu 12.04) recognize it as headset, but I can't choose it as device for input/output (no such device).

    I have a Creative headset and I do experience something similar.

    What I do is to shut down the headset, restart bluetooth and connect the headset again. It eventually works.

    See here for a bug report, maybe you are seeing the same thing as me:

    D'oh, I erased the hard drive to install Ubuntu before realising I needed to flash the BIOS. Does anyone know of a way to flash the BIOS from linux?

    I've been using the SToggle command to great effect that michel.kluger posted, and because I use Xubuntu I made some changes to it to set the resolution of the HDMI display with xrandr. This might not even be necessary for ubuntu 12.04 w/ gnome

    Code:
    #!/bin/bash
    # Sound Toggle
    # By Charles Cruz
    #
    # The following script toggles the between laptop speakers and hdmi audio (if detected).
    # Version 1.0
    #
    #modified by senorgomez
    #
    #Added xrandr commands to set resolution of HDMI screen for desktop environments that don't do that automatically.
    
    
    USERID="$(cat /var/run/ConsoleKit/database | grep -B 6 is_active=true | grep uid= | cut -f 2 -d '=')"
    USER="$(grep $USERID /etc/passwd | cut -f 1 -d ':')"
    HDMI_STATUS="$(cat /sys/class/drm/card0-HDMI-A-1/status)"
    
    if [ "${HDMI_STATUS}" = connected ]; then
    # Set audio to go out on HDMI
    sudo -u $USER pactl set-card-profile 0 output:hdmi-stereo
    
    # Find the max res of the display we are connected to
    res="$(xrandr -q|grep HDMI -A 1|tail -n 1|awk '{print $1}')"
    
    #set the HMDI screen to that resolution and place it on the right of the laptop screen
    sudo -u $USER xrandr --output HDMI1 --mode $res
    sudo -u $USER xrandr --output HDMI1 --right-of LVDS1
    
    else
    #set audio to go out on minijack
    sudo -u $USER pactl set-card-profile 0 output:analog-stereo+input:analog-stereo
    
    #set resolution to auto, max on laptop screen
    sudo -u $USER xrandr --auto
    fi
    
    exit 0
