Problèmes liés au Lenovo Yoga 700 Wifi
Je viens d'installer Ubuntu 15.10 sur mon nouveau Lenovo Yoga 700 (modèle 80QD). Je l'ai depuis la ligne de commande, et j'utilise actuellement mon WiFi pour écrire ceci. Cependant, Connection Manager ne me permet pas de configurer le WiFi via l'interface utilisateur.
Premier problème: les fichiers de firmware /lib/firmware/iwlwifi-7265D-14.ucode et /lib/firmware/iwlwifi-7265D-15.ucode étaient manquants (message d'erreur du pilote sur dmesg). Je les ai téléchargés depuis https://github.com/OpenELEC/iwlwifi-firmware/tree/master/firmware , car je ne trouvais pas de paquet ubuntu contenant ces deux fichiers.
Deuxième problème: le gestionnaire de réseau refuse de gérer ce périphérique wifi. Ce premier symptôme ressemblait à la désactivation du widget "commutateur" WiFi du menu réseau situé en haut à droite du gestionnaire de fenêtres Unity. Essayer de l'allumer a provoqué l'animation d'avant en arrière. Actuellement, après tous mes jeux, le wifi semble grisé.
J'ai exécuté le script d'informations WiFi, joint ci-dessous. Il est clair que la commande rfkill voit un "blocage matériel". Maintenant tout d’abord: je n’ai pas de commutateur d’arrêt matériel sur cet ordinateur portable (Manuel d’utilisation: https://download.lenovo.com/consumer/mobiles_pub/yoga_700-14isk_ug_en_201509.pdf ). Deuxièmement, j'utilise actuellement le wifi, configuré à partir de la ligne de commande. Ceci peut également être vu ci-dessous, car le wifi est associé avec succès (j'ai utilisé wpa_supplicant). Et troisièmement, il affirme également que le bluetooth est bloqué, mais j'utilise également mes écouteurs bluetooth lors de l'écriture, et je les ai configurés à l'aide de l'interface utilisateur Ubuntu, qui a très bien fonctionné.
J'ai aussi remarqué:
GENERAL.STATE: 20 (unavailable)
GENERAL.REASON: 2 (Device is now managed)
ci-dessous sur les informations du gestionnaire de réseau pour cet appareil, mais je suis moins au courant de ce que cela signifie réellement.
Merci, j'aimerais bien, sauf régler ce problème pour le long terme, si vous pouviez évoquer un hack à court terme. Sinon, je vais devoir continuer à configurer le WiFi à partir de la ligne de commande, ce qui est assez gênant.
Edit 2: Comme demandé, voici les étapes que j’ai effectuées pour vous connecter à mon réseau domestique sans fil:
Sudo ifconfig wlp1s0 up
wpa_passphrase shlompiya <password> > /tmp/conf
Sudo wpa_supplicant -Dwext -iwlp1s0 -c/tmp/conf
Sudo dhclient wlp1s0
Sudo sh -c 'echo nameserver 8.8.8.8 > /etc/resolv.conf'
En ce qui concerne le mode avion: j'ai oublié de mentionner que j'ai joué avec, excuses-moi. Le mode avion a modifié les paramètres du logiciel bloqués lors de l'appel de rfkill list
J'ai réussi à bidouiller ça: j'ai recompilé le paquet network-manager, et je lui ai fait ignorer complètement le mode rfkill "matériel bloqué". Après ce piratage, l'interface utilisateur fonctionne (mais très probablement, j'ai cassé la fonctionnalité du commutateur de mise à mort du logiciel rf). Cela fonctionnera pour moi pour le moment, essayons de résoudre ce problème pour le prochain gars ;-)
la recompilation et le correctif ressemblent à ceci:
Sudo apt-get build-dep network-manager
mkdir ~/laptop
cd ~/latop
apt-get source network-manager
cd network-manager-1.0.4
vim src/nm-rfkill-manager.c
line 168:
return RFKILL_HARD_BLOCKED;
replace
// return RFKILL_HARD_BLOCKED;
// PASH PATCH
nm_log_warn (LOGD_RFKILL, "PASH PATCH: overrided hardware killswitch state to not killed");
return RFKILL_UNBLOCKED;
Fin de l'édition 2
Script d’informations Wifi, suivi des journaux du gestionnaire de réseau joints ci-dessous: Modifier: en raison du nombre limité de caractères sur la longueur de la question, j’ai supprimé les blocs relatifs aux ponts virtuels (appartenant à libvirt, autant que je sache).

aussi, attacher systemctl status network-manager -n 1000 -l. Si je comprends bien les messages de journalisation, il détecte effectivement la destruction matérielle par rf, et vous pouvez également voir le passage en mode "indisponible", ce que je ne comprends pas ce que la raison "géré" signifie. Éditer: cela a dû être raccourci en raison de la limitation du nombre de caractères pour la longueur de la question.

Futurs demandeurs d'aide:
La faute semble être avec un pilote ideapad_laptop buggy, qui n'est pas un problème unique pour cet ordinateur portable/modèle.
pour résoudre le problème n ° 2, une solution possible consiste simplement à mettre le pilote sur une liste noire, comme suggéré ici: https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Notebooks/Wifi-is) -hardware-disabled/td-p/1307405
N'oubliez pas de résoudre le problème # 1, vous devrez télécharger le nouveau firmware: https://github.com/OpenELEC/iwlwifi-firmware/tree/master/firmware
Pour référence future: voici un lien vers le bogue sur un modèle différent sur lunchpad, j'ai ajouté un commentaire à propos de ce modèle spécifique afin qu'il puisse être ajouté au pilote. Si cela se reproduit sur AUTRES MODELES, lancez dmidecode et vérifiez si votre modèle de machine figure dans la liste du pilote drivers/platform/x86/ideapad_laptop.c ( https://bugs.launchpad.net/ubuntu/+source/linux-lts -utopic/+ bug/1397021 )
