I have this too. Happens when gdm's autologon or timedlogon is true.
What happens is when system is booting gdm is auto/timed loging the user in and the "could not update ICEauthority file" error appears, if OK is clicked I get another message (usr/lib/libgconf2-4/gconf-sanity-check-2 has quit with state 256) and then just an empty wallaper. To get in to the system I move to a free text tty and run "sudo /etc/init.d/gdm restart". When gdm restarts everything is ok. -- Automatic login fails and computer hangs (Lucid) https://bugs.launchpad.net/bugs/577563 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
