Please reboot and go to Recovery Mode.

Then choose 'root shell'.

Then type:
chown bob:bob /home/bob/.ICEauthority
chmod 600 /home/bob/.ICEauthority
exit

## Replace 'bob' with your username

btw. it can happen when a user runs a GUI with 'sudo' instead of 'gksudo'.

IM also having the same prob. "Could not update ICEauthority file /home/username/.ICEauthority"

The above fix is not working for me. i did it but still this appears.

and at the same time sound of my laptop stopped working. i donno if these two r related, but wanted to tel u as it happened together and might help deciding whats happened.
When i try to open sound configuration it says "Waiting for sound system for respond".
And there is no sound after i log in. Login screen does have sound.

help needed
and im a noob

I need to add that I'm having this same problem. On a Pentium 4 machine... I was doing fine until I ran out of hard drive space, and then things have not been right about this. The above suggestions to fix did not work, at all.
