SUMMARY

The discussion centers on a GNOME login error encountered on Ubuntu 6.10, specifically the message "Unable to determine the address of the message bus." This issue arose after changing icon themes, leading to a semi-crash and subsequent failures to boot beyond the splash screen. The user accessed failsafe mode and received an error regarding the GNOME Settings Daemon, which may affect themes and settings. The recommended solution includes updating to the latest version of Ubuntu and consulting relevant documentation on dbus-launch and dbus-daemon.

I was just changing icon themes, when all of a sudden the icons on the desktop and the panel disappeared.(I've been noticing that using the Themes Manager makes the Processes applet go all blue) I was still able to access the windows, but nothing much else. (It was a semi-crash, so to speak) So I rebooted the computer, but it would not go beyond the splash. I rebooted again, and entered the failsafe mode, and that's where I'm typing this message from.

As soon as I logged in, an error message popped up
There was an error starting the GNOME Settings Daemon.

Some things, such as themes, sounds, or background settings may not work correctly.

The last error message was:

Unable to determine the address of the message bus (try 'man dbus-launch' and 'man dbus-daemon' for help)

GNOME will still try to restart the Settings Daemon next time you log in.

I'm not sure what to do to get back to my original desktop. Please help.
