fedora开机出现There is a problem with the configuration server. ，/usr/libexec/gconf-sanity-check-2 exited with status 256

Install problem!

The configuration defaults for GNOME Power Manager have not been installed correctly. Please contact your computer administrator

As per my findings, I am getting this problem only because I have accidentally changed permissions on /tmp folder. The owner of /tmp folder become other than root and also no other user have read, write or execute rights on /tmp folder. I just changed its owner again to root, group also to root and gave every body read, write and execute rights.

chown -rwx root:root /tmp

chmod 777 /tmp
