Comment 2 for bug 1420430

It is possible that this is not a bug, but that I somehow messed-up my system. To try to solve the problem, I deleted and reinstalled network-manager and unity-greeter, and restarted. The problem persisted. I then deleted unity-greeter, and restarted, but then could not get a logon prompt.

In the "Privacy" system setting, I have "record activity" set to "off". Because of that, (I think) I normally got a plain message at startup, "Unable to write bytes". Then unity greeter would start, and I would log on (I have a password set). But without unity-greeter (and using unity-2d) it would not give me a logon prompt, even after answering all the questions it asked me. All I could get was "Unable to write bytes", from which point all I could manage to do was ctrl-alt-del, which rebooted, after which I still could not log on. So I reinstalled 12.04 LTS, wiping out the previous installation. Now it has been updated and works fine. I am using the following:

network-manager-gnome 0.9.4.1-0ubuntu2.3
network-manager 0.9.4.0-0ubuntu4.4.1
unity-greeter 0.2.9-0ubuntu1.4

with no problems or bugs. You guys that work on bugs might want to try logging on with a password needed, using unity-2d, and without unity-greeter, and with "Record Activity" set to "off". But be prepared to lose the entire system! Now that might be buggy. But that would be a different bug, not this one.

Thank you for your attention to this.
