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):

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.

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).
How it possible to resolve this problem?
Sorry for my English. ))
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
