Comment 5 for bug 588155

i have encountered this trouble too. However it doesn't occur at each boot.

Dist : Ubuntu 10.04 x64
GPU : nvidia 8600GT with driver of serie 256 (from x-swat-x-updates ppa)
GDM : autostartup (without delay)

I tried to got the debug output doing the modification of the attached patch, but the trouble doesn't appears doing this (at least for the 5 tries I made since this). Maybe others will success in doing this.

My idea is that there is a race condition between dbus and g-s-d that prevent g-s-d to start if dbus isn't totally ready, but I can't prove it, and I don't now how to log the startup of dbus and g-s-d.
