Ubuntu .ICEAuthority problem

Recently I’ve rebooted my VMWare Ubuntu machine and after the login sequence I’ve received an error whose log I give bellow.

/etc/gdm/PreSession/Default: Registering your session with wtmp and utmp

** (gnome-session:23826): WARNING **: Unable to lock ICE authority file:

The solution I’ve found on a forum( http://www.linuxquestions.org/questions/showthread.php?s=ef11204ac2b7cacdd6cfc0b651512838&t=403160&page=3 ).  To save you the trouble of digging for it in the posts, I’ll just mention what I did to make Gnome start :

Open the failsafe terminal and edit the file /etc/gdm/Xsession. Add the following lines right under the PROGNAME = Xsession line :

ICEAUTHORITY=”tmp/ICEauthority-${root}”
export ICEAUTHORITY

This worked fine for me since Gnome is now normally started.
