= Une carte hybride intel / nvidia =
Ce système à la base pensé pour économiser de l'energie en fait dépenser pas mal aux linuxiens depuis que nvidia a annoncé que les drivers linux pour cette carte hybride attendraient...

L'un des problèmes récurrent est l'activation/désactivation de la puce graphique Intel ou de la carte graphique nVidia. Le BIOS de certains PC ne le permettant pas (Schenker XMG p501, Clevo p105...), ce n'est pas la peine d'essayer tant que cette fonctionnalité n'est pas accessible.

= Identifier sa carte =
Taper dans un terminal :
 sudo lshw -C video

= Mettre à jour son système =
== Noyau ==
La partie Intel de la carte graphique commence à être bien supportée à partir du noyau 2.6.35

Pour mettre à jour son noyau, notamment sous ubuntu 10.04 lucid, quelques ressources :
* Activer dans synaptic enable the "lucid-proposed" repository. Le noyau 2.6.38 semble bien marcher
* Attention, désintaller le driver "nouveau" (driver nvidia libre) à désinstaller car conflit dans mon cas 
  sudo apt-get remove --purge xserver-xorg-video-nouveau
et le blacklister :
  sudo gedit /etc/modprobe.d/blacklist.conf
ajouter dans le fichier :
  blacklist nouveau
* La "Mainline" du kernel linux empaquetée : http://kernel.ubuntu.com/~kernel-ppa/mainline/

== Drivers graphiques ==
=== Plusieurs sources à comparer... ===
* Pour des drivers stables issus de backport ou de mises à jour : https://launchpad.net/~ubuntu-x-swat/+archive/x-updates
 ppa:ubuntu-x-swat/x-updates
* Pour "casser" son X avec des morceaux plus expérimentaux : https://launchpad.net/~xorg-edgers/+archive/ppa
 ppa:xorg-edgers/ppa
=== Intel ===

=== Nvidia ===
''a priori pas nécessaire de passer par là''
* Installation du driver à partir du site de NVIDIA
** Télécharger le dernier driver là : http://www.nvidia.fr/Download/index.aspx?lang=fr
** Installer les linux-headers correspondants à son noyau
 uname -a #pour connaitre son noyau
 sudo apt-get install linux-headers-votrenumdenoyau #pour avoir les en-têtes du noyau pour compil
 Ctrl+alt+F3 #Basculer sur une fenetre console 
 sudo /etc/init.d/gmd stop #Arrêter le serveur X
 cd ..... #Aller là où vous avez mis le driver téléchargé
 sudo chmod +x NVIDIA*    #Pour le rendre executable
 sudo sh NVIDIA.............run   #Pour le lancer

répondre oui à la licence et non pour la génération d'un fichier de config (sinon votre ordi essayera de booter sur la carte nvidia)

= Installer un système qui permette de solliciter la carte NVIDIA =
Suite à fork, il y a plusieurs projets pour faire marcher la carte nvidia avec le système optimus, le premier est un fork du MrMee original, le deuxième est issu de la première team mais a pris un autre nom
* Bumblebee https://launchpad.net/~bumblebee/+archive/stable
* Ironhide (uniquement > lucid) https://launchpad.net/~mj-casalogic/+archive/ironhide/

== Panneau de configuration nvidia ==
Une fois Bumblebee installé, tenter :
 optirun nvidia-settings -c :8

= Pure Data vs Optimus =
 optirun pdextended
