Comment 17 for bug 1388130

Okay, on vivid, unity-greeter 15.04.2-0ubuntu1 re-introduces this bug.

I have a vivid image that was up-to-date as of Fri 5 Dec. In this snapshot, with applying any updates, I can connect to protected WiFi just fine.

However, today something landing from proposed re-introduced this bug, and I noticed that unity-greeter was among the updates.

So I re-imaged and then upgraded only unity-greeter:

sudo apt-get update
sudo apt-get install unity-greeter

After a reboot, the password dialog wont show when I try to connect to protected WiFi (same symptom as Utopic).

Interestingly enough, unity-greeter was one of the many things I tried back-porting and it didn't fix this on Utopic, although now I can't recall whether I did that back-port in isolation or whether there were other backports I was testing at the same time.

Ah, also note that unity-greeter 15.04.2-0ubuntu1 does *not* break WiFi on Intel GPU systems. This is still only a problem on systems with Nvidia GPUs running the proprietary nvidia driver (might effect the nouveau driver too, not sure either way on that one).
