Résumé

Cette page décrit comment configurer et optimiser le système d'exploitation GNU/Linux Debian Etch sur un ordinateur portable Thinkpad T43 (2668WR9) en utilisant le noyau (kernel) 2.6.20 et les pilotes propriétaires ATI.
On suppose que le système d'exploitation de base est déjà installé; l'installation ne pose aucun problème particulier si l'on a la bonne idée de la lancer en passant l'option libata.atapi_enabled=1 au kernel.
Ne pas hésiter à me faire part de toute remarque qui pourrait améliorer cette documentation.

Les commandes délimitées par un filet rouge comme celle-ci une commande sont à exécuter en tant que root.
Les commandes "dans le texte" sont notées ainsi: une commande.

Configuration

tar xjf linux-2.6.20.tar.bz2
wget -O linux-2.6.20/.config http://www.piprime.fr/files/articles/linux/config/t43/includes/config-2.6.20
make oldconfig

• J'ai choisi d'activer le support pour les périphériques 'frame buffer' (CONFIG_FB=y) et les pilotes VESA VGA graphics (CONFIG_FB_VESA=y) ce qui n'est pas recommandé pour utiliser les pilotes propriétaires ATI fglrx.
  Je les utilise pourtant mais il faut prendre soin de passer les bons paramètres au kernel dans le boot loader (voir la section sur Boot loader).
  Ce qui est recommandé:

  CONFIG_FB is not set
  CONFIG_FB_VESA=y is supposed to work, but it appears that it can cause "mtrr overlapping" errors;
  CONFIG_FB_RADEON=y definitely causes problems, so disable it.
      

  
  Voir ici pour plus d'informations.
• Depuis la version 2.6.16 du kernel, le support pour iptables est désactivé. Mon fichier de configuration le réactive mais je pense qu'il est loin d'être optimisé à ce sujet.
• Pour modifier ou visualiser facilement le fichier de configuration avant de compiler le noyau exécuter cette commande:

  make menuconfig
      

  
  

Patch et compilation

cd linux-2.6.20
make

bzcat ../suspend2-2.2.9-for-2.6.20.patch.bz2 | patch -p1

CONFIG_SUSPEND2=y
CONFIG_SUSPEND2_FILE=y
CONFIG_SUSPEND2_SWAP=y
CONFIG_CRYPTO_LZF=y

make menuconfig
  

Création et installation du paquet non-initrd kernel pour Debian

make-kpkg clean && fakeroot make-kpkg --revision=T43.1.0 kernel_image
cd ..

Installation des pilotes

[ -e /usr/local/pi/src/modem/ ] || mkdir /usr/local/pi/src/modem/

cd /usr/local/pi/src/modem/
unzip hsfmodem_7.60.00.04full_i386.deb.zip

• si la licence n'a pas été rentrée lors de l'installation, le modem est bridé.
  Pour entrer la licence, il suffit d'exécuter en tant que root la commande hsfconfig --license;
• les pilotes du modem peuvent être manuellement déchargés avec la commande hsfstop;
• pour désinstaller les pilotes du système il suffit de lancer la commande (toujours en tant que root) hsfconfig --uninstall;
• s'il y a des déconnexions fréquentes ou une mauvaise connexion, il faut vérifier les dernières informations de statuts.
  Elles peuvent être obtenues soit avec la commande modem AT#UG ou avec cat /proc/driver/hsf/0/lastcallstatus.
  Alternativement le pilote peut être configuré pour enregistrer les données lors d'un mauvais fonctionnement en ajoutant le paramètre loglastcallstatus=1 à l'option hsfserial dans /etc/modules.conf.
