Compositeur - ATI (radeon)

Bonjour,

Je viens de passer à xfce et je suis totalement conquis par sa rapidité et "simplicité". Cependant, certaines questions demeurent.

Tout d'abord, pour ce qui est de la transparence que l'on peut avoir en activant le compositeur ; j'ai bien réussi à obtenir l'onglet Compositeur dans le Paramètre --> Peaufinage des fenêtres mais alors le système est fortement ralenti (affichage et déplacement des fenêtres). Je possède une carte ATI Mobility Radeon X700 et j'utilise le driver libre radeon (qui me permettait de faire tourner Beryl correctement). Voici mon xorg.conf :

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

Le direct rendering est bien activé :

brice@ubuntu:~$ glxinfo |grep render
libGL warning: 3D driver claims to not support visual 0x4b
direct rendering: Yes
OpenGL renderer string: Mesa DRI R300 20060815 TCL

et voilà ce que j'obtiens comme fps sachant que conky et l'horloge xtu tournent en fond :

brice@ubuntu:~$ glxgears -printfps
libGL warning: 3D driver claims to not support visual 0x4b
14926 frames in 5.0 seconds = 2985.131 FPS
14942 frames in 5.0 seconds = 2988.394 FPS
15024 frames in 5.0 seconds = 3004.680 FPS
14953 frames in 5.0 seconds = 2990.501 FPS
14966 frames in 5.0 seconds = 2993.040 FPS
14885 frames in 5.0 seconds = 2976.894 FPS
14959 frames in 5.0 seconds = 2991.661 FPS
14888 frames in 5.0 seconds = 2977.511 FPS
14751 frames in 5.0 seconds = 2950.037 FPS
14950 frames in 5.0 seconds = 2989.827 FPS
14799 frames in 5.0 seconds = 2959.743 FPS
14912 frames in 5.0 seconds = 2982.261 FPS
14843 frames in 5.0 seconds = 2968.593 FPS

Je vais poser mes autres questions dans d'autres posts.

Merci de vos idées et réponses, à bientôt.

Re : Compositeur - ATI (radeon)

J'ai le même problème que toi avec ma radeon X300,impossible d'utiliser correctement le compositeur.... et je n'ai toujours pas trouvé de solutions.

Re : Compositeur - ATI (radeon)

Re : Compositeur - ATI (radeon)

@xilef : j'utilise le driver libre radeon Et j'ai bien rajouté une section "Extensions" avec dedans Composite à Enable...

Et pourtant le compositeur est tout lent ; et ce n'est pas parce que fglrx ne supporte pas l'extension Composite que le compositeur n'est pas utilisable avec, un des posts sur le forum A quoi resseble votre environnement le disant.

A bientôt.
