Bug#648666: May fail to restart due to stale .ICEauthority lock

[Ben Hutchings]

Package: gdm3
Version: 3.0.4-3
Severity: important

I had to reboot the system after hitting a bug in the graphics driver
that left the screen blank.  I rebooted by pressing (not holding) the
power button so that there was a more-or-less normal shutdown; but
it's possible that the X server hung and gdm3 was not shut down
cleanly.

On the next boot, gdm3 displayed the 'wait' cursor for a few seconds;
then it displayed an error dialog with the message 'Could not update
ICEauthority file /var/lib/gdm/.ICEauthority' and only action button
'Log Out'.  I removed /var/lib/gdm/.ICEauthority* and was then able to
restart gdm3 succesfully.

Ben.
