= Overview =
|
||
|
|
|
||
|
|
Most of the features seem to be working with Linux >= 3.9
|
||
|
|
|
||
|
|
== Hardware ==
|
||
|
|
|
||
|
|
* CPU Intel(R) Core(TM) i5-3317U CPU @ 1.70GHz
|
||
|
|
* RAM 4 GB
|
||
|
|
* HDD 128GB SSD
|
||
|
|
* Screen 13.3-Inch Screen
|
||
|
|
* Graphics Intel HD Graphics 4000, Ivy bridge
|
||
|
|
|
||
|
|
= Configuration =
|
||
|
|
|
||
|
|
Full configurations is in my
|
||
|
|
[https://raw.github.com/grwlf/nixpkgs/local/machines/samsung-np900x3c-v2.nix nixpkgs branch]. Note, it requires several local packages.

|
|
|
||
|
|
=== Touchpad ===
|
||
|
|
|
||
|
|
Touchpad is detected as 'ETPS/2 Elantech Touchpad'. xf86-input-synaptics handles
|
||
|
|
it well. Corresponding config lines:
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
services.xserver = {
|
||
|
|
synaptics = {
|
||
|
|
enable = true;
|
||
|
|
accelFactor = "0.05";
|
||
|
|
maxSpeed = "10";
|
||
|
|
twoFingerScroll = true;
|
||
|
|
additionalOptions =
|
||
|
|
''
|
||
|
|
MatchProduct "ETPS"
|
||
|
|
Option "FingerLow" "3"
|
||
|
|
Option "FingerHigh" "5"
|
||

|
Option "FingerPress" "30"
|

Option "MaxTapTime" "100"
|

Option "TrackstickSpeed" "0"
|

Option "LBCornerButton" "2"
|

Option "CoastingFriction" "20"
|
||
|
|
'';
|
||
|
|
};
|
||
|
|
};
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
=== Wireless ===
|
||
|
|
|
||
|
|
System requires iwlwifi-6000g2b-6.ucode in order to work. I've extracted the
|
||
|
|
file from some debian package and placed it into /root/firmware. Corresponding
|
||
|
|
config settings:
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
hardware.firmware = [ "/root/firmware" ];
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
= Problems =
|
||
|
|

=== BIOS problems ===
|
||
|
|
I had to disable SSD boot completely in order to boot from USB. Just changing boot priority didn't help.
|
||
|
|
|
||
|
|
Fix: Update BIOS up to recent version
|
||
|
|
|
||
|
|
=== Battery ===
|
||
|
|
Battery charging/discharging indicator doesn't work good.

=== Lid ===
|
||
|
|
Acpi thinks lid is always open
|
||
|
|
<pre>
|
||
|
|
[ierton@greyblade:~]$ cat /proc/acpi/button/lid/LID0/state
|

state: open
