[Résolu] Sarge : 3D avec Intel 845G

[tchoyy]

Bonjour,

Je suis sous Debian Sarge.
Voilà un bon moment que je bloque sur l’activation du direct rendering. J’ai une carte intégrée intel 82845G (autrement dit 845G), le driver dans XFree86 est i810.

Je vous poste ma config de XFree :

On constate bien le direct rendering: No

dans mon lsmod, j’ai bien :

intel_agp 22816 1
agpgart 34664 3 intel_agp
i830 78596 2

(il semble que le dri utilise le i830, qui se refere à la même carte d’après mes recherches).

Je me suis dit que peut être ma carte n’était pas prise en compte par le noyau, mais non :

<> /dev/agpgart (AGP Support)
<> Intel 440LX/BX/GX, I8xx and E7x05 chipset support

[] Direct Rendering Manager (XFree86 4.1.0 and higher DRI support)
<> Intel 830M, 845G, 852GM, 855GM, 865G

Donc c’est bien activé…

ce qui m’eclate le plus c’est le log de XFree qui me dit que tout est ok ! (je vous épargne le blabla qui ne nous concerne pas en prenant que des extraits traitants du DRM/DRI)

Boah, ça n’a pas l’air de motiver grand monde

[PengouinPdt]

Pour ce que j’en ai compris, les drivers OpenSource d’Intel apportent la 3D sur ces nouveaux chipsets - dit GMA -, avec un “support” élargi aux puces créés à partir de l’i830.

Ce pilote est crée pour le serveur X, en relation avec mesa.

intellinuxgraphics.org/

In addition to Intel® 965GM chipset support, the X.org 2.0 driver adds native video mode programming support for all chipsets from i830 forward

Première option : basculer sur le server Xorg

Pour ce qui est du server XFree86, malheureusement, les “choses” n’évoluent pas … aussi bien.
La page suivante du projet XFree86 à propos du pilote i810, qui est celui qui supporte cette puce et les suivantes, informe de ces points suivants :

The driver supports hardware accelerated 3D via the Direct Rendering Infrastructure (DRI), but only in depth 16 for the i810/i815 and depths 16 and 24 for the 830M and later.

A-priori, il supporte la 3D… sauf que, si j’ai bien compris cela :

[quote]
By default 8 Megabytes of system memory are used for graphics. For the 830M and later, the default is 8 Megabytes when DRI is not enabled and 32 Megabytes with DRI is enabled. This amount may be changed with the VideoRam entry in the config file Device section. It may be set to any reasonable value up to 64MB for older chipsets or 128MB for newer chipets. It is advisable to check the XFree86 log file to check if any features have been disabled because of insufficient video memory. In particular, DRI support or tiling mode may be disabled with insufficient video memory. Either of these being disabled will reduce performance for 3D applications. Note however, that increasing this value too much will reduce the amount of system memory available for other applications.[/quote]

Il y a des problèmes de performances …

Tu peux essayer ces quelques informations :
-1- Activer la video ram, et sytem ram dans le BIOS de ton pc,
[quote]For the i810 and i815 familiy of chipset, operating system support for allocating system memory for video use is required in order to use this driver. For the 830M and later, this is required in order for the driver to use more video ram than has been pre-allocated at boot time by the BIOS.[/quote]
-2- Positionner l’Option VideoRam dans ton fichier de config XFree,
[quote]This amount may be changed with the VideoRam entry in the config file Device section[/quote]
Mais attention, autant de mémoire tu alloueras à ta carte, autant tu en réduiras pour le système :
[quote]Note however, that increasing this value too much will reduce the amount of system memory available for other applications.[/quote]
Essaye d’abord de fixer la valeur à 64 Mo, puis une fois que toutes ces modifications sont faites, redémarre ton serveur graphique.

(cf la doc du chipset Intel i810 relatif au server XFree)

Dernier point : “patience et longueur de rage font que force” …
Autrement dit, on n’est pas à ta botte, ne l’oublie pas. Personne n’est censé te répondre ici ou ailleurs en temps et en heure où tu l’estimes, donc sois patient. Ta dernière réflexion ne motive pas à t’aider … comprends-le.

PS : Pour finir, mon anglais est approximatif … donc, d’autres pourront rectifier au cas où …

[tchoyy]

Le passage à la etch m’a tout corrigé, donc ça marche…

Je te trouve gonflé quand même, déjà d’un je n’ai pas dit quelque chose du style “Mais répondez moi !!” Je n’ai forcé ni pressé personne et de deux, mon deuxième message a été posté quand même une journée après le second, ce n’est pas comme si je postais toutes les deux heures pour avoir une réponse !
