The Intel GMA 3600 series is a family of integrated video adapters based on the PowerVR SGX 545 graphics core. It is used in the Atom N2600 and Atom N2800.

## News

Intel release a graphics driver for PowerVR: http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=21938

Be aware: The current version 1.03 (10/01/2012) has the following dependencies:

Bundle "Ant"

    * Kernel: 3.0.0
    * Mesa GL: 7.9
    * Xorg: 1.9

Bundle "Bee"

    * Kernel: 3.1.0
    * Mesa GL: 7.11
    * Xorg: 1.11

This means, unleass you run a really outdated system this driver is useless for Arch-Linux.

## Kernel module driver

Kernel has an experimental support for this adapter since v3.3. Since Kernel v3.5 the GMA3600 power features are supported. Now suspend/resume should properly work.

If after resume you got a blank screen try the following

    sudo touch /etc/pm/sleep.d/99video

## Xorg driver

At the moment there is no accelerated driver for Xorg Server, but some support is available using the Xorg modesetting driver:

    pacman -S xf86-video-modesetting

/etc/X11/xorg.conf.d/20-gpudriver.conf:

    Section "Device"
        Identifier "Intel GMA3600"
        Driver     "modesetting"
    EndSection

The modesetting driver allows disabling/enabling LVDS, VGA, etc. ports and changing resolution using xrandr.

The following can be used to disable LVDS and force enable VGA if needed.

/etc/X11/xorg.conf.d/20-gpudriver.conf:

    Section "Device"
        Identifier "Intel GMA3600"
        Driver     "modesetting"
        Option     "Monitor-LVDS-0" "Ignore"
        Option     "Monitor-VGA-0" "Monitor"
    EndSection

    Section "Monitor"
        Identifier "Ignore"
        Option     "Ignore"
    EndSection

    Section "Monitor"
        Identifier "Monitor"
        Option     "Enable"
    EndSection

## Playing video

It is unable to utilize whole chip power and play fullHD movies using graphics acceleration. As workaround you could utilize the maximum power of your Atom CPU to decode video:

    mplayer -lavdopts threads=4 -fs myvideo.avi

## Cedarview-drm module port

You can get around the Kernel 3.1.0 requirement from the package by using the following git repository1 (thanks to thomas001):

     git clone https://github.com/thomas001/cedarview-drm.git cedarview-drm-master
     (Intended for Linux Kernel releases 3.7 to 3.9)

     git clone -b linux-3.5 https://github.com/thomas001/cedarview-drm.git
     (Intended for Linux Kernel releases 3.4 and 3.5)

Currently the following kernel versions are tested:

    * vanilla 3.7.8
    * vanilla 3.4.32 --- use linux-3.5 branch

You can either compile the module directly using a command like:

     make -C /lib/modules/`uname -r`/build M=`pwd` KMYDIR=`pwd`

or you employ DKMS:

     cp -r /path/too/cedarview-drm /usr/src/cedarview-drm-1.0.3
     dkms add cedarview-drm/1.0.3

Afterwards you have to build the module and maybe regenerate your initramfs, as follows:

     mkinitcpio -p linux
