[ATI rv370 (Radeon X300 SE)] Impossible d'activer OPENGL dans plasma 5

[Mickael]

Bonjour,

Je viens de passer l'ordinateur de mes parents sous plasma 5 (KDE4 avant) et je suis maintenant dans l'impossiblité d'activer OPENGL 2 dans les réglages du compositeur. Le rendu revient à XRENDER automatiquement.

Quelques infos techniques:

Code : Tout sélectionner

lspci | grep -i display
01:00.1 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] RV370 [Radeon X300 SE]

Dans journalctl, j'ai un message très utile pour la résolution...:

Code : Tout sélectionner

sept. 06 10:42:50 archlinux kwin_x11[6269]: kwin_core: OpenGL driver recommends XRender based compositing. Falling back to XRender.
sept. 06 10:42:50 archlinux kwin_x11[6269]: kwin_core: To overwrite the detection use the environment variable KWIN_COMPOSE
sept. 06 10:42:50 archlinux kwin_x11[6269]: kwin_core: For more information see http://community.kde.org/KWin/Environment_Variables#KWIN_COMPOSE
sept. 06 10:42:51 archlinux kwin_x11[6269]: kwin_core: Failed to initialize compositing, compositing disabled

Je précise que j'ai bien évidemment installé les pilotes qui vont bien:

• xf86-video-ati
  mesa-libgl
  mesa-vdpau (à noter que pour celui-là et vu le modèle de ma carte, je ne suis pas certain qu'il sert à quelque chose)

Le module radeon est bien chargé:

Code : Tout sélectionner

lsmod | grep radeon
radeon               1454080  7
ttm                    69632  1 radeon

i2c_core               45056  5 drm,i2c_i801,drm_kms_helper,i2c_algo_bit,radeon

Enfin la version du kernel:

uname -a
Linux archlinux 4.1.6-1-ARCH #1 SMP PREEMPT Mon Aug 17 09:07:24 CEST 2015 i686 GNU/Linux

J'y suis depuis hier et là j'avoue que ça m'agace car tout ce qui a besoin de l'acceleration graphique est ultra-lent...
Une idée de comment résoudre ça?

Merci par avance pour votre aide.

Bonjour,
Je suis curieux de savoir où il existe un tel réglage, je ne le retrouve plus ? De plus je croyais que openGL était devenu obligatoire.
Peux tu donner le début du .xsession-errors (tout ce qui te semble pertinent)

[Doline]

Salut,

On retrouve ce réglage dans Affichage et surveillance > Compositeur.
Tu es sûr d'avoir tous les paquets Qt 5 nécessaires d'installés ?
Pour ma part je les ai tous exceptés enginio, serialport, wayland et websockets.

Bonjour,

@benjarobin: ok je vais essayer de te fournir le .xsession-errors dès que possible (comme expliqué la machine n'est pas chez moi). Pour ce qui est du réglage @Doline t'a indiqué la réponse.

@Doline: j'ai installé plasma-desktop qui est certes minimal mais doit néanmoins contenir dans ces dépendances le nécessaire pour utiliser l'accélération graphique. A noter que la même install sur un PC portable Asus réalisé cette nuit permet d'utiliser OpenGL 2.0 sans soucis (la carte graphique est une intel) donc j'ai de gros doute sur un soucis de paquet manquant.

À priori tu es sur une machine 32bits. As-tu essayé avec les paquets lib32-mesa et lib32-mesa-libgl ?

[Mickael]

@Doline: sauf erreur de ma part ces paquets sont utiles pour exécuter des applications 32bits lorsque l'OS est en 64bits. Dans mon cas de figure (OS 32bits) ces paquets sont inutiles.

Pour preuve:
Le parquet dont tu parles fait partie de repo "multilib": https://www.archlinux.org/packages/mult ... ib32-mesa/
L'article officiel qui explique que ce dépôt ne sert que pour les OS 64bits sur lesquels on souhaite exécuter des applis en 32bits: https://wiki.archlinux.org/index.php/Multilib
