    Re: Samsung series 9

    I got it to work after all. Turns out I added an empty line to /lib/udev/keymaps/force-release/samsung-900x3c, and this file is read by a very dumb sh script that doesn't tolerate empty lines.

    I'm noticing bad wifi performance using 12.10 and the open source broadcom driver. Does the closed-source one work better?

    Talking Re: Samsung series 9

    Can't believe nobody else has responded to this - THIS WORKS!

    Touchpad was the only thing I was unhappy with ("New" Series 9 running Ubuntu 12.10 with Gnome Classic), and now everything's perfect with it.

    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

    I have the same feeling... bad response of the touchpad.

    I'll try this later on.

    It's better, but still misses a lot of soft-click's.

    Another annoying situation is with multiple touches (fingers) we cant move the cursor... This doesn't happen with Mac's touchpad.

    Thanks for your advice... For me it does not work even after removing all empty lines... I see the unity notification after pressing FN+F9 or FN+F10, but it does not has effect and the bar in the notification box stays always full.

    Re: Samsung series 9

    Hi guys, i recently bought a Series 9 900x4c and as many of you, i am experiencing
    the ACPI problems(my battery status doesnt change, either suspend on lid close works)

    Before installing ubuntu, i completely wiped out win8 and now i cant upgrade
    the BIOS. The thing is i dont even know if its necessary: my BIOS version is P02ABK,
    can somebody confirm that it is the latest one for my model?

    Most of cases of P08AAH upgrade referred to 900x3b models.

    Re: Samsung series 9

    I'm having a strange problem with my new Samsung 900x4C running the P02ABK firmware (I believe that's the latest) that I wonder if anyone else is experiencing. I've been able to get most things to work but, while digging into controlling the keyboard backlight, found that the samsung-laptop module is not loaded properly. As such, I don't have a /sys/devices/platform/samsung directory. The problem:

    Code:
    sudo modprobe samsung-laptop debug=1
    Results in the following in dmesg
    Code:
    samsung_laptop: This computer does not support SABI
    I have tried using 3.2, 3.4, and 3.5 kernels all on 12.04 LTS and am getting this error on all of them. Makes me wonder if the new BIOS moved away from SABI or something.

    Has anyone seen anything like this? Does anyone have ideas about what might be going on? Has anyone gotten the keyboard backlight to work with the P02ABK firmware?

    Thanks a ton.
