Debian9 stretch - Xorg - carte video SiS671

Support Debian
#1

Je migre d’Ubuntu vers Debian. J’ai commencé sur Ubuntu avec la version 9.10 et suis actuellement avec 16.04. A chaque changement de version j’ai rencontré des problèmes pour obtenir une résolution de 1280x800 avec un driver sis puis sisimedia au lieu de 1024x768 qu’offre le driver vesa lorsque le système ne reconnait pas la carte installée.
Je retrouve le même problème avec Debian9 - 64bit et seul le driver “vesa” fonctionne avec une résolution de 1024x768.

J’ai téléchargé le dernier driver “sisimedia” trouvé sur le net, en fait un dossier .rpm transformé en .deb avec alien et installé le driver sisimedia_drv.so dans /usr/lib/modules/drivers/ Ce driver a été compilé en janvier 2017 pour “mageia cauldron” et c’est le plus récent que j’ai pu trouver.
J’ai démarré le PC portable en mode “recovery” pour arriver à root.
J’ai exécuté la commande #X -configure et obtenu un fichier /root/xorg.conf.new
J’ai exécuté la commande #X -conf /root/xorg.conf.new pour terster ce xorg.conf
L’écran démarre pendant une dizaine de secondes puis retourne au mode console avec l’annonce d’une “segmentation fault”

Deux questions

  • peut-on, comme dans d’autres forums entrer ces fichiers dans une boite dans laquelle ils se dérouleront ?
  • quelqu’un peut-il m’aider à anlyser ce problème où manifestement le driver employé entraine un usage interdit de la mémoire ?
#3

Peut-être à cause d’un de ces changements dans le noyau et Xorg :

From Linux 4.8, several changes have been made in the kernel
configuration to ‘harden’ the system, i.e. to mitigate security bugs.
Some changes may cause legitimate applications to fail, and can be
reverted by run-time configuration:
- On most architectures, the /dev/mem device can no longer be used to
access devices that also have a kernel driver. This breaks dosemu
and some old user-space graphics drivers. To allow this, set the
kernel parameter: iomem=relaxed

xorg-server (2:1.17.3-1) unstable; urgency=medium
The Xorg server is no longer setuid root by default. This change reduces the
risk of privilege escalation due to X server bugs, but has some side effects:

  • it relies on logind and libpam-systemd
  • it relies on a kernel video driver (so the userspace component doesn’t
    touch the hardware directly)
  • it needs X to run on the virtual console (VT) it was started from
  • it changes the location for storing the Xorg log from /var/log/ to
    ~/.local/share/xorg/

On systems where those are not available, the new xserver-xorg-legacy package
is needed to allow X to run with elevated privileges. See the
Xwrapper.conf(5) manual page for configuration details.

#4

Peut-être mais sur ma version Ubuntu 16.04, que j’ai conservé comme système principal en attendant d’avoir mis au point mon Debian 9 j’ai maintenant un noyau 4.10.0-14-generic(i686) et le SiS671 fonctionne parfaitement avec le driver sisimedia_drv.so en me donnant un écran 1280x800 très détaillé et brillant alors que le driver “vesa” ne donne que 1024x768 beaucoup moins détaillé et plus terne.
La raison est peut-être que le driver que j’ai trouvé est compilé pour un système “mageia-cauldron” et pourtant le driver que j’utilise sur Ubuntu provient du même site mageia.
Peut-être faudrait-il que je trouve le source de ce driver sisimedia et que je le compile dans Debian 9 64-bit ?

#5

Qu’est-ce que ça te coûte d’essayer les deux contournements mentionnés dans l’annonce ?

#6

OK j’essaie cela demain car ici il est bientôt 22h00 et je ferme tout pour cette nuit. Merci j’étudierai tout cela demain.

#7

Aucun effet de “iomem=relaxed”. Il semble que cette solution s’applique à un problème de Virtualbox, or j’ai installé Debian9 sur une nouvelle partition réalisée avec gparted.
Par contre je ne comprends pas bien la deuxième proposition et en examinant mes fichiers le Xorg.0.log est toujours stocké dans le dossier /var/log. Je n’ai rien dans ~/.local/share/xorg/

Ce qui est certain c’est qu’au cours du démarrage de l’interface graphique après avoir lancé pour essai #X -config /root/xorg.conf.new le système essaie d’utiliser un espace mémoire déjà attribué au bout d’une dizaine de secondes et, par mesure conservatoire arrête le processus et revient au mode console. Reste à savoir quel est exactement le problème d’adressage mémoire et comment y remédier ?

#8

Nouvelle info : le bloquage du serveur survient avant l’apparition de l’icone du pointeur souris sur l’écran.

#9

Comme j’ai xserver-xorg-legacy installé sur Ubuntu16.04 je l’ai aussi installé sur Debian9 stretch et ai aussitôt essayé de relancer l’ensemble X depuis une console en mode root # X -config /root/xorg.conf.new.
Toujours le même plantage avec segmentation fault.

Comme legacy s’adresse à des drivers anciens (uniquement Nvidia ? auquel cas je ne serais pas concerné) .

J’ai comparé les fichiers /etc/X11/Xwrapper.config de mes deux systèmes Ubuntu et Debian. Ils sont identiques et se terminent par une seule ligne de configuration

Il n’y a pas de
