# Configuration
My particular model is Asus N82JV-VX038V but the contents of the page should remain valid for every N82JV[[1]](http://www.notebookcheck.net/Review-Asus-N82JV-Notebook.29437.0.html) model.
## CPU
Works out of the box.
Follow the [SpeedStep](/index.php/SpeedStep "SpeedStep") guide to enable speed-stepping.
## Video
This laptop sports two gpus. The Intel GMA HD (Core ix integrated) and the Nvidia Geforce GT 335M, with the ability to switch granted by Nvidia Optimus technology.
### Intel
Follow these guides: [Xorg](/index.php/Xorg "Xorg") and [Intel](/index.php/Intel "Intel")
No problems detected. VGA out and HDMI working.
### Nvidia
The official proprietary Nvidia drivers for linux do not support Nvidia Optimus yet.
#### Switching / Using Nvidia card
While it still isn't possible to *switch* in the manner that Optimus is supposed to switch, in order to make use of the dedicated graphic card you need to use [Bumblebee](/index.php/Bumblebee "Bumblebee"). In short, **it is possible to run a specific program with Nvidia**, while the rest of the system is relying on the Intel card.
**Note:** Bumblebee's development is rapidly progressing, so be sure to check it's website[[2]](https://github.com/MrMEEE/bumblebee) regularly; it's also worth checking Linux Hybrid Graphics blog[[3]](http://linux-hybrid-graphics.blogspot.com/) and the mailing list[[4]](https://lists.launchpad.net/hybrid-graphics-linux/).
#### Disabling the Nvidia card
There's more than one method to do this. Namely with **vgaswitcheroo** (not working reliably yet with these cards) and **acpi_call (AUR[[5]](https://aur.archlinux.org/packages.php?ID=39470))**, which is recommended.
**Note:** If you use the AUR version, the steps are different than the ones below, but they are explained during/after install; the scripts can be easily adapted to the new locations, if necessary
##### acpi_call (manual)
In order to switch following hack is available[[6]](http://linux-hybrid-graphics.blogspot.com/2010/07/using-acpicall-module-to-switch-onoff.html)[[7]](http://github.com/mkottman/acpi_call).
*What it is*: A kernel module that enables you to call parameterless ACPI methods by writing the method name to /proc/acpi/call, e.g. to turn off discrete graphics card in a dual graphics environment (like NVIDIA Optimus).
Instalation:
```
git clone [http://github.com/mkottman/acpi_call.git](http://github.com/mkottman/acpi_call.git)
cd acpi_call
make
sudo insmod acpi_call.ko
./test_off.sh
```
Usage:
```
# turn off discrete graphics card
echo '\_SB.PCI0.PEG1.GFX0.DOFF' > /proc/acpi/call
# turn it back on
echo '\_SB.PCI0.PEG1.GFX0.DON' > /proc/acpi/call
```
###### Run on Startup
If you want run it on every startup add these lines to `/etc/rc.local`
**Note:** Running this without a delay on Kernel 2.6.35.x has problems (Boots fine but X and tty do not show up; to avoid that, simply add `sleep <time>` before these lines and remember that sleep affects every line below it. If you mess up or decide to test it, just boot into recovery mode and edit `/etc/rc.local` from cli, to either add the delay or remove the lines altogether
```
# Disable Nvidia
insmod <path to acpi_call dir>/acpi_call.ko
echo '\_SB.PCI0.PEG1.GFX0.DOFF' > /proc/acpi/call
```
If want, you may verify the power usage, on battery, with `grep rate /proc/acpi/battery/BAT0/state`. There should be a difference of about 7500 mW in battery usage.
###### Enable/Disable Scripts
You can easily create a couple of scripts to enable and disable it.
```
#/bin/sh
# Disable Nvidia
sudo insmod /home/xehoz/build/acpi_call/acpi_call.ko
echo '\_SB.PCI0.PEG1.GFX0.DOFF' > /proc/acpi/call
```
```
#/bin/sh
# Enable Nvidia
sudo insmod /home/xehoz/build/acpi_call/acpi_call.ko
echo '\_SB.PCI0.PEG1.GFX0.DON' > /proc/acpi/call
```
`chmod +x` both of them and type `sh <name you've given them>` to use them.
## Audio
Follow the official documentation: [ALSA](/index.php/ALSA "ALSA") and [PulseAudio](/index.php/PulseAudio "PulseAudio")
**Note:** From my experience [OSS](/index.php/OSS "OSS") doesn't work
While it outputs sound to the speakers, the headphone jack won't work, and the speakers won't mute when a headphone is plugged in and the integrated mic won't work either.
In order to fix this, follow these steps.
1\. Install ALSA drivers available at Realtek [[8]](http://218.210.127.131/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false)
```
tar xvf LinuxPkg_x.x
tar xvf alsa-driver-1.0.xx
cd alsa-driver-1.0.xx
./configure --with-cards=hda-intel
make
make install
```
**Note:** Realtek's ALSA drivers, currently 1.0.23-5.15rc5, aren't compiling properly in kernel 2.6.35\. As an alternative, download the latest alsa-driver snapshot from here[[9]](http://ftp.kernel.org/pub/linux/kernel/people/tiwai/alsa/alsa-driver/alsa-driver-snapshot.tar.gz) (tested with 01/09/2010 snapshot)
2\. Add `options snd-hda-intel index=0 model=auto` to `/etc/modprobe.d/modprobe.conf`.
Open `/etc/modprobe.d/sound.conf` and add:
```
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
```
### HDMI
Sound through HDMI works, but requires that the sound profile (mixer) be changed manually (not really a problem).
## Touchpad
1\. Follow the [Synaptics](/index.php/Synaptics "Synaptics") guide.
Type `xinput list` . What you want to see:
`⎜ ↳ ETPS/2 Elantech Touchpad id=16 [slave pointer (2)]`
However, you'll see that the system is misinterpreting the touchpad for a wheel mouse. This is because this laptop (and so many others recently) is using an Elantech Touchpad. In order to fix it, enter this in the command line:
```
echo "options psmouse force_elantech=1" | sudo tee -a /etc/modprobe.d/psmouse.conf
sudo rmmod psmouse && sudo modprobe psmouse
```
Then, open `/etc/X11/xorg.conf.d/10-synaptics.conf`. A bare minimum configuration requires this text:
```
Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
Option "LeftEdge" "130"
Option "RightEdge" "840"
Option "TopEdge" "130"
Option "BottomEdge" "640"
EndSection
```
**Note:** While I settled with these coordinates, they may require tuning: [Touchpad Synaptics#Synclient](/index.php/Touchpad_Synaptics#Synclient "Touchpad Synaptics").
### Working 10-synaptics.conf
Here's a fully working 10-synaptics.conf with Edge Scrolling, Two Finger Scrolling and with middle mouse click (LTCornerButton and RTCornerButton) on the top corners activated. Circular Scrolling works, but it's deactivated.
`/etc/X11/xorg.conf.d/10-synaptics.conf`
```

# Webcam
Working, since version v4l-utils 0.8.1-1 (in previous versions the picture was upside down).
```
$ lsusb |grep Chicony
Bus 002 Device 003: ID 04f2:b1bb Chicony Electronics Co., Ltd
```
# Function Keys
Most of them do work. Exceptions are the multimedia player commands (fn+arrows), fn+c, fn+v and fn+F9 (which should disable the touchpad). It should be possible to have them all working by following [Extra keyboard keys](/index.php/Extra_keyboard_keys "Extra keyboard keys").
