problem with X.Org and GLX in debian sid

[adiakin]

Hello, I install X.Org 6.8.2 in debian sid, also install nvidia drivers 7667
in xorg.conf comment GLcore and dri modules, uncomment glx module. After starting X server I get error about that composite extension cannot run with nvidia GLX.
in Driver section:

Section "Device"
    Identifier  "Generic Video Card"
    Driver      "nvidia"
    Option      "NoLogo" "true"
    Option      "RenderAccel" "true"
#   Option      "UseFBDev"      "true"
EndSection

and

Section "Extensions"
Option "Composite" "Enable"
EndSection

What can I do to fix this problem?
P.S even if I comment glx module kde write that I need to write RenderAccel and enable composite
P.P.S sorry for my english )

By default the drivers don't support the composite extension. It is quite buggy and not all features are supported (can't be mixed with GLX/Xv stuff). If you really want to enable it at the following line to the screen or device section (doesn't matter which):
Option "AllowGLXWithComposite" "1"
