Comment 77 for bug 151544

AthlonXP 2400+, nvidia GeForce FX 5700LE, same problem, very long login, usually no error but sometime after hanging for a while with the yellow screen, it pops up an error in a small window saying:

"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:

Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

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

 I click "Close" and then my desktop appears with the wrong resolution; wide screen instead of 1280x1024.
I logout & login and it's fine.
