User selector doesn't have focus from login screen after screen turned off

[Will Cooke]

In gdm usually the user name is pre-selected. This means that you can just hit enter and then put your password in. In Disco this is the case on boot up. If you wait for the screensaver to kick in (i.e. boot and do nothing for 5 mins) then when the screen comes back again the username is not selected.

Steps To Reproduce
1. Boot Disco
2. Once you get to the login screen, notice that your username is selected.
3. Do nothing, touch nothing. Wait for the screensaver to kick in and blank the screens.
4. Wiggle the mouse, dismiss the clock screen and you will be back at the login screen
5. Notice that you user is no longer selected and in order to log in you have to move the mouse and click on the user name

What should happen
The username should be pre-selected so that I can log in without having to use the mouse.

Status changed to 'Confirmed' because the bug affects multiple users.

Confirmed, however, step 4 isn't accurate.

4. Wiggle the mouse and you will be at the screensaver clock / wallpaper. Drag the screen up or press enter.

Thanks Popey, I've updated the description.

Something to note: While I was testing this I noticed that a fraction of a second before the screen starts fading to black you can see that focus is taken away from the user selector. So it seems it's not returned when it "wakes up" again.

Reassigned to gnome-shell, which provides the GUI here.

This bug is being marked as notfixing for the Disco release. This doesnt mean it won't get fixed, but it won't block release.

[Sebastien Bacher (seb128)]

Setting to low, it's not an action users are going to do often and the workaround is easy. Would still be nice to upstream/get fixed though
