All it needs to contain is the following.
Section "Device" Identifier "Radeon" Driver "radeon" Option "NoAccel" "true" EndSection
Hi ALex,
Following your advise, I've putted it in a xorg.conf Consequence : system disabled Gallium then returns on Software Rasterizer methode. It results that it improves perf, glxgears (without vblank=0 option set) run now 102 fps (60 before)
Regards,
