That is the source of the problem. Something is wrong with your profile that removed your user's ability to modify your gconf files.
A variety of things could have occurred to get your system in this state, including disk corruption. You can try restoring your permissions with the following command, and then rebooting: sudo chown -R youruser:youruser /home/youruser/.gconf* (replace "youruser" with your actual username). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/714015 Title: blank screen saver buttons do NOT work in ati 9600 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
