[hoary] Xorg freeze with shadow enabled

[Shixin Zeng]

Geforece 2 MX400
nvidia binary driver 6179 from linux-restriced-modules
I edited Xorg.conf to be like:

Section Device
 Driver "nvidia"
 Option "RenderAccel"
EndSection

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

After I start "xcompmgr -c -f" the whole system freeze and I have to 'reset'
