    Re: Samsung series 9

    Has anyone tried a dual-boot installation with Windows 8 on a NPC900X4C?

    Will it differ much from http://askubuntu.com/questions/16659...boot-windows-7 ?

    I'm essentially worried that the poster there did not create any recovery procedure so that things could be reverted to factory settings in case something went wrong.

    I've created dual-boot installations with XP+Linux extensively. I'm just affraid of the UEFI mechanism this time.

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.
    I also have no /sys/devices/platform/samsung directory.
    And this is what I get:
    root@ugiulio/:# modprobe samsung-laptop debug=1
    FATAL: Error inserting samsung_laptop (/lib/modules/3.5.0-21-generic/kernel/drivers/platform/x86/samsung-laptop.ko): No such device

    I am running Ubuntu 12.10 on a np900x3c-a02 with the p02abk firmware.

    Any suggestion?

    Re: Samsung series 9

    I've just installed Ubuntu 12.10 on my Samsung 900X4C. However, I can't get the keyboard backlights to work.

    I added the keymaps as per https://help.ubuntu.com/community/SamsungSeries9 (section Function Keys). They all seem to work. But regarldess of pressing Fn+F9 or F10, I get:
    1. No lights in keyboard
    2. Toggler in top right corner always pops-up as maxed out (ie, "full light")


    Has this ever happened to any of you?

    Unhappy Re: Samsung series 9

    I installed Kubuntu 12.10 on a Samsung 900X4D today. Everything works fine, except the Trackpad which has the well-reported problem of jerkiness..

    It's quite shocking how much movement the cursor makes when my finger is not moving. As soon as I unplug the machine and go to battery all movement stops when my finger isn't moving and the trackpad seems to work fine.

    I am going to buy a surge protector tomorrow to see if that fixes the problem with the laptop is plugged in.

    Does anyone have any advice? It's very annoying that what is a great looking machine is basically unusable out of the box when plugged in.

    Re: Samsung series 9

    Unfortunately I don't have any suggestions but I can confirm that I experiencing same problem. I've been searching for days to get the keyboard backlight to function properly.
    The keymaps has been updated as suggested by several.
    Have you found any solution yet?

    Im on Ubuntu 12.10, np900x3c-a04 with p02abk firmware.

    I have the same problem. I have stumbled upon https://bugs.launchpad.net/ubuntu/+s...x/+bug/1012284 . I will try to see if this might be a similar issue.

    It seems that this is caused by UEFI... I have tried enabling only CSM and booting a Live USB. It seems to work. I will describe this more thoroughly if it turns out to work.

    Ubuntu 12.10 on Samsung Series 9 with everything working (including keyboard backlight)

    Samsung Series 9 is a praised machine. Despite this, I used half a day troubleshooting why the keyboard could not be lit (as the last thing not working). It turned out that the kernel module samsung_laptop could not be loaded because "samsung_laptop: This computer does not support SABI" (from dmesg). By Googling, I found out that it was because of UEFI. I found as follows:
    I stumbled across
    https://bugs.launchpad.net/ubuntu/+s...x/+bug/1012284
    which led to problems with the file drivers/platform/x86/samsung-laptop.c. Searching for "ubuntu 12.10 drivers/platform/x86/samsung-laptop.c" I was led to http://osdir.com/ml/kernel-team/2012-12/msg00752.html which indicated the problems with UEFI. To confirm my findings, I enabled CSM only and tried booting using a Live USB. You can read more about UEFI and CSM at http://en.wikipedia.org/wiki/Unified...ware_Interface .

    As I could not easily find the solution, I now post this.

    My version of the Samsung Series 9 is NP900X3C-A04 with BIOS/firmware version P02ABK but the following is maybe true to other versions, too.

    To get a fully working Ubuntu 12.10 system, do as follows:

    1) Go to System settings (what was called the BIOS in "old" days)
    1.1) On the Advanced tab, disable Fast BIOS mode. (I also enabled "Battery Life Cycle Extension" for better battery life but this setting has nothing to do with this.)
    1.2) On the Boot tab, disable Secure Boot and then select "CSM OS" as the OS Mode Selection
    1.3) Set Boot Device Priority such that you can install Ubuntu (this would normally be to set USB HDD as the first boot device and use a USB drive to install Ubuntu)

    2) Install Ubuntu and boot it

    3) Update the system:
    3.1) sudo apt-get update
    3.2) sudo apt-get upgrade

    4) Activate the Fn keys as described on https://help.ubuntu.com/community/SamsungSeries9#FnKeys

    5) Additional conveinient fixes as those described on http://www.rileybrandt.com/2012/11/18/linux-ultrabook/ and http://www.math.helsinki.fi/mathphys...ulcio_new.html

    5) Reboot and enjoy!

    Re: Samsung series 9

    The reason I installed Ubuntu on UEFI was that this was the only way my laptop would boot from USB.
    Well, I just tried to change BIOS setting to CMS, with this setting Ubuntu won't boot. So I tried the third alternative, CMS and UEFI (i dont recall the exact name), a strange thing happend. Backlight of my keyboard is on(!) but my screen shows nothing, I'm not sure if it hung or what happend.
    I tried reboot a couple of times but the only way to come back and answer this thread was to go back to UEFI.

    I really don't understand this how you did this. But I'm happy for you!
    Did you reinstall Ubuntu? Or did you just change to CMS and then successfully rebooted?
