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 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/984785 Title: .goutputstream files polluting $HOME Status in Light Display Manager: New Status in X.Org X server: New Status in “lightdm” package in Ubuntu: Confirmed Status in “lightdm” source package in Precise: Confirmed Bug description: .goutputstream files polluting $HOME.
