Gnome startup-problems/error after new installation

[Michael Loose]

Hello to everyone on the list and thx for paying attention
to this note. 
While trying to "reanimate" ;-) my iMac the horror below happened.
As this renders me helpless and totally stops my shy attempt to
run Linux on a Mac, i would greatly appreciate any help. 

Specs:
dual boot Sirius/MacOS 9 on /dev/hda on an iMac DV450.
Default "workstation-install" with packets for Gnome-Desktop added
during installation process, Network-Configuration as DHCP-client,
network device not enabled at boot-time.

During installation everything seemed to do fine, the system boots 
up to runlevel 3 by default, after login and  "startx" the XServer
starts (black screen and the cross-cursor appears, followed by the
YDL-Logo) and the the following error-messages appear:

1. "There was a problem registering the panel with the bonobo-activation
server. The error code is 3. The panel will now exit."

2. "There was an error starting the GNOME-Settings Daemon. Some things,
such as themes, sounds or background images may not work correctly.The
Settings Daemon restarted too many times. GNOME will try to restart the
Settings Daemon next time you log in."

3. "Nautilus can't be used now, due to an unexspected error"


And it leaves me alone in black silence...


kind regards
