Comment 4 for bug 569667

The same problem here, but I think this is a wider problem, too - the RC (specifically speaking - the updates after RC) really rendered my computer useless:
1. I have to enter all the passwords for everything all over again (I get the communication with keyring error)
2. neither nm-applet nor gnome-power-manager start with the session (yes, they are in the session startup items), I have to start them manually later
3. the whole admistrative access scheme seems not to work : I can't add any new users (the system won't bring up the unlock/authorization dialog so nothing happens), I can't add any hardware drivers (the system tells me I don't have the permissions, unless I start jockey with gksudo, but I shouldn't be supposed to!)
4. the nvidia driver doesn't work any more (I don't know in what way that has to do with the rest but all the above symptoms appeared at the same time)
In sum, my system is suddenly half useless and a big hassle to work with; I know it is RC still but 4 days before release this seems to be a major regression!

Just to make sure it was not my specific configuration/upgrade that was the cause I re-installed RC from scratch and always ended up with the above. Any help would be very much appreciated, Thanks!
