1. Scaricare il pacchetto psb-kernel-* da http://swiss.ubuntuforums.org/showpost.php?p=7773647&postcount=13

2. Aggiungere i repository digitando in un terminale i seguenti comandi:

   sudo echo 'deb http://ppa.launchpad.net/ubuntu-mobile/ppa/ubuntu jaunty main' >> /etc/apt/sources.list.d/ubuntu-mobile.list
   
   sudo echo 'deb-src http://ppa.launchpad.net/ubuntu-mobile/ppa/ubuntu jaunty main' >> /etc/apt/sources.list.d/ubuntu-mobile.list
   
   sudo echo 'deb http://ppa.launchpad.net/albertomilone/poulsbo-graphics/ubuntu jaunty main ' >> /etc/apt/sources.list.d/poulsbo-graphics-alberto-milone.list
   
   sudo echo 'deb-src http://ppa.launchpad.net/albertomilone/poulsbo-graphics/ubuntu jaunty main' >> /etc/apt/sources.list.d/poulsbo-graphics-alberto-milone.list

3. Aggiungere le chiavi

   sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C6598A30
   
   sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 99C0198F
   
   sudo apt-get update
   
   sudo apt-get install  dkms fakeroot
   
   sudo apt-get install libdrm-poulsbo1
   
   sudo apt-get install poulsbo-driver-2d poulsbo-driver-3d psb-firmware

4. Installare i pacchetti psb-kernel-*

   sudo dpkg -i psb-kernel-*
   
   sudo echo "blacklist i915" >> /etc/modprobe.d/blacklist.conf
   
   sudo update-initramfs -u

5. Con un editor di testo ed i privilegi amministrativi creare il file /etc/X11/xorg.conf ed incollare in questo le seguenti righe:

   Section "Device"
           Identifier      "GMA500"
           Option "AccelMethod" "EXA"
           Option "DRI" "on"
           Option "MigrationHeuristic" "greedy"
           Option "IgnoreACPI" "yes"
           Driver "psb"
   EndSection
   
   Section "DRI"
       Mode    0666
   EndSection

with following content and whitelist psb in /usr/bin/compiz by adding "psb" to the WHITELIST line. Kernel parameters (in grub).

If you have a Vaio-P or if you are experiencing extremely slow performance (less than 14 fps running "/usr/bin/xscreensaver/glblur -fps -window") add "mem=2000mb" to /etc/default/grub, at the end of GRUB_CMDLINE_LINUX_DEFAULT, if using grub2, or at the end of the "# defoptions=" line in /boot/grub/menu.lst. For both grub versions run update-grub after editing those files. This reserves memory for the video driver and should improve your 3D performance.

Attention: For machines with only 1GB ram, the entry should be "mem=980mb"

Supporto Poulsbo (GMA500) in Intrepid (8.10) e Jaunty (9.04)

Se si posssiede un kernel che si è compilati da soli, oppure non si stà utilizzando l'ultimo kernel fornito per Intrepid o Jaunty, installare il pacchetto psb-kernel-source (e assicurarsi che gli header per il kernel siano disponibili) e rimuovere allora il pacchetto psb-modules.

Install packages

sudo adduser $USER video

sudo modprobe psb
