The GNOME session manager was unable to lock....

[Hektor]

I get this error on one of my older Linux Ubuntu installs. Anyone know how to fix it?

The GNOME session manager was unable to lock the file '/home/hektor/.ICEauthority'. Please report this as a GNOME bug. Sometimes this error may occur if the file's directory is unwritable, you could try logging in via the failsafe session and ensuring that it is.

Is this the login screen? I mean when it boots and then asks you for username and password?

Have you looked at that file and determined if it is writeable?

Yes, the file was there and I set it to 777. It did not fix it. In the end I just created a new user and this worked fine.
