gnome power manager error and other errors

[m.nassar]

Hi all I'm running fedora 11 as a fresh installation since the day it was finally released , after running yum -y update last night , weird things happened.
First the behaviour of the startup changed , there are things like barrier errors and things like that , Is there any log file that I can post here ? ,
Second at the login screen for the gnome session I get an ERROR "The configuartion defaults for GNOME power manager have not been installed correctly , Please contact your system admin" , and when i try to log in nothing happens , just the mouse cursor and a black screen , I tried switching to text mode , running yum remove gnome-power-manager and then yum install gnome-power-manager , then reboot. The error disappears but I still can't login via GNOME session , I'm currently on KDE , any ideas about that ?

Thanks in advance guys

Did you already look into the log files for any suspicous errors or warnings? Xorg log and messages, both located in /var/log, would be the most interesting.
With "fresh installation" do you mean, you never did an upgrade until last night? If thats true, you probably got a whole lot of updates to install. Did you notice any problems during the update?

This may be a candidate for the most misleading error message of all time!

You will get this message if gconf-sanity-check-2 tries to write a test file into /tmp and can't read it back. It can be caused if you erase the /tmp directory and allow the system to create a new one automatically. It does so with the permissions set to read and execute only, so the test file cannot be written.

Change the permissions of /tmp to 777 and it will fix it.

chmod 777 /tmp is the command line.

I reinstalled the system also the first time it happened to me.
