## Settings

#### Video

Laptop comes with two GPU's (main INTEL and dedicated NVIDIA):

    [punky@laptop ~]$ lspci | grep VGA
    00:02.0 VGA compatible controller: Intel Corporation Atom Processor Z36xxx/Z37xxx Series Graphics & Display (rev 0e)

For Intel HD install: xf86-video-intel

    [punky@laptop ~]$ lspci | grep 3D
    01:00.0 3D controller: NVIDIA Corporation GF117M [GeForce 610M/710M/810M/820M / GT 620M/625M/630M/720M] (rev a1)

For using Nvidia install bumblebee along with Nvidia and Intel drivers.

### Lan

Works fine with no configuration required.

### Wifi

Wifi does not work out of box, because you need to install driver from AUR:

    broadcom-wl-dkms

Ethernet works good, so you can use cable for installing wifi driver.

Warning: Using the proprietary driver with KMS leads to sporadic OS freeze! I suppose that is problem with sporadic OS freezes.

### Audio

Install PulseAudio.

After installation, reboot the laptop to ensure all modules are loaded. Audio works well both with pure ALSA and with PulseAudio.

### Touchpad

Touchpad works with: xf86-input-synaptics

### Brightness

Brightness does work out of box, but you can not change value with keyboard combo, buttons are not mapped at all (fn + F5 / fn + F6), untill you use the kernel parameter `acpi_osi= acpi_backlight=native` to your bootloader. `acpi_osi=` it's indeed followed by a blank space + `acpi_backlight=native`. This is only way when backlight can be controled with keyboard combo keys.

### Webcam

Cheese works fine out of the box.

### Bluetooth & Card reader

I did not test bluetooth because I am not using it, also I did not test card reader, but I think that card reader works fine.

## Problems

### Led

I did not find a way to resolve problem with led for wifi. Every other led (battery, hdd, backlight) works good, but led for wifi does not work even keyboard combo (fn + F2) for enabling / disabling wifi works.
