Comment 51 for bug 984785

I have the same issue with Ubuntu 12.04.
I made Comparison between Ubuntu 11.10 and Ubuntu 12.04 against "Shut down". Both install (11.10 and 12.04) are in the same PC and both use Lightdm.

1) with Ubuntu 11.10 :

- PC restart : "Shut down" > "Restart"
- At login screen, I press Ctrl+Alt+F1 and check .Xauthority file :
ls -l .Xauthority
-rw------- 1 malbo malbo 0 2012-05-25 11:39 .Xauthority

- I press Ctrl + Alt + F7 to return to login screen and log in. Since my graphic session, I check .Xauthority :
ls -l .Xauthority
-rw------- 1 malbo malbo 67 2012-05-25 11:41 .Xauthority

2) with Ubuntu 12.04

- PC restart : "Shut down" > "Restart"
- At login screen, I press Ctrl+Alt+F1 and check .Xauthority file :
ls -l .Xauthority
-rw------- 1 malbo malbo 51 mai 25 11:57 .Xauthority

- I press Ctrl + Alt + F7 to return to login screen and log in. Since my graphic session, I check .Xauthority :
ls -l .Xauthority
-rw------- 1 malbo malbo 51 mai 25 12:00 .Xauthority

My Comment :
Ubuntu 11.10 works good with "Shut down" : .Xauthority file is 0 bytes just before the opening session (it goes to 67 bytes after the login).
Ubuntu 12.04 is wrong with "Shut down" : .Xauthority file is not zero byte just before the login (it is 51 bytes and I checked
it is in the state of the opening of the previous session)
I think this anomaly is related to the creation of .goutputstream files
