My particular model is Asus N82JV-VX038V but the contents of the page should remain valid for every N82JV model.
Works out of the box.
Follow the SpeedStep guide to enable speed-stepping.
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.
No problems detected. VGA out and HDMI working.
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. In short, it is possible to run a specific program with Nvidia, while the rest of the system is relying on the Intel card.
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), which is recommended.
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).
git clone http://github.com/mkottman/acpi_call.git cd acpi_call make sudo insmod acpi_call.ko ./test_off.sh
# 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 StartupIf you want run it on every startup add these lines to
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.localfrom 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.
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.
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 
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
options snd-hda-intel index=0 model=auto to
/etc/modprobe.d/sound.conf and add:
alias snd-card-0 snd-hda-intel alias sound-slot-0 snd-hda-intel
Sound through HDMI works, but requires that the sound profile (mixer) be changed manually (not really a problem).
1. Follow the Synaptics guide.
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
/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
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.

Suspend to RAM
I achieved Suspension to RAM by using pm-utils with either the uswsusp and kernel method.
1. Follow the pm-utils article . It is quite extense and can be confusing, but, if I recall, this is the very minimum of what is needed to do:
pacman -S pm-utils uswsusp
1.2 To a file inside
SLEEP_MODULE="uswsusp" #SLEEP_MODULE="kernel" HIBERNATE_MODE="shutdown"
1.3 Add the
resume hook to
/etc/mkinitcpio.conf, before filesystems.
HOOKS="base udev autodetect block resume filesystems"
1.4 Rebuild the initrd image with
mkinitcpio -p linux.
Now, to the hardware specific part.2. Add
After a surge of updates, somewhere on the end of November/start of December (bug report), suspend to ram only works if nouveau is explicitly disabled in rc.conf. Since nouveau isn't related to the ability to power the nvidia card off, powering it off is still possible, even after disabling that module.
!nouveau to the
MODULES line in
rc.conf. It should look like this:
MODULES=(fuse acpi-cpufreq cpufreq_ondemand cpufreq_powersave !snd-pcm-oss vboxdrv !nouveau)
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
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.
