I hope this will be useful but it might be a tangent. Gnome has given me black
screen on startup on two different systems in the past month. Is your
installation using the gnome greeter? In the first system I tracked the problem
back to gtk trying to contact the greeter via dbus when there was no greeter or
it was not responding. The second system is still black screen, and I am still
troubleshooting. Relevant error messages appear in the 'messages' file, not the
X log. And at the risk of sounding growly, the gtk messages were sparse and
cryptic. Do you see a pointer on black, or nothing at all? Cheers -- Rick
