Bonjour,
J'ai un petit probleme sur l'acceleration 3D avec ati 9200:
j'obtien un resultat pas terrible du tout:
 
[pqcuong@localhost pqcuong]$ glxgears
285 frames in 5.0 seconds = 57.000 FPS
297 frames in 5.0 seconds = 59.400 FPS
294 frames in 5.0 seconds = 58.800 FPS
296 frames in 5.0 seconds = 59.200 FPS
297 frames in 5.0 seconds = 59.400 FPS
297 frames in 5.0 seconds = 59.400 FPS
297 frames in 5.0 seconds = 59.400 FPS
297 frames in 5.0 seconds = 59.400 FPS
297 frames in 5.0 seconds = 59.400 FPS
 
[pqcuong@localhost pqcuong]$ lsmod | grep fglrx
fglrx 223292 9
 
[pqcuong@localhost pqcuong]$ glxinfo | grep direct
direct rendering: Yes
 
 
j'ai procédé de regarder mon xorg.conf, il me parait bien configuré:
...................

pourriez me dire pk ca ne marche pas mon Acceleration 3D ?

une question, en étant root, est ce que glxgears est bien en 3D accéléré ?  

ca fait pareil
 
[root@localhost pqcuong]# glxgears
238 frames in 5.0 seconds = 47.600 FPS
297 frames in 5.0 seconds = 59.400 FPS
297 frames in 5.0 seconds = 59.400 FPS

quand tu fais glxinfo, affiche t-il les différentes extensions OpenGL supportées ?  
Dans le fichier xf86config ou xorg, dans la section module tu as bien Load "dri" et Load "glx" ?

oui:
OpenGL extensions:
    GL_ARB_multitexture, GL_EXT_texture_env_add, GL_EXT_compiled_vertex_array,

glu extensions:
 
et les dri et glx sont chargé
 
 
 

quel est l'intérêt des pilotes ATI avec une 9200 ? ils sont déjà accélérés de base par les drivers libres

je pense k c'est une question de choix,
reviens à mon sujet:
que pensez vous? (j'ai ati 9200)
#lspci | grep ati
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R250 Lf [Radeon Mobility 9000 M9] (rev 01)
 
le résultat surprenant, ma carte graphique est identifié comme Radeon 9000,
(sous windows elle est ati 9200)
mais quand on cherche à comprendre sur ati 9200:
 
"The 9200 mobility is essentially the same core as the 9000 and is
often identified as a 9000 on that basis.  The important point is that
this does not include the Lh variant...."
(mon OS fedora core 2, kernel 2.6.9)
 
 
 

Mmmmm euh ta question en amene une autre chez moi: j'ai effectivement un souci selon que je sois en root ou pas: sous X en root (bouh pas bien), acceleration parfaite (glxgears: 6000fps), mais en utilisateur "normal", direct rendering=no... je ne parviens pas à voir la différence dans l'utilisateur du module, qu'on siot en root ou pas. Une suggestion peut etre?
Thanks !
