|
||
|
|
||
|
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 "MaxDoubleTapTime" "150"
|
||
|
Option "FastTaps" "1"
|
||
|
Option "VertTwoFingerScroll" "1"
|
||
|
Option "HorizTwoFingerScroll" "1"
|
||
|
Option "TrackstickSpeed" "0"
|
||
|
Option "LTCornerButton" "3"
|
||
|
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.

|
||
|
