lightdm shutdown opens a window without focus

Bug Description

Users cannot shutdown from the greeter screen using only the keyboard. This means that some users that rely on accessibility features cannot shutdown from the greeter at all. (or devices that don't have a pointer at all)

[Test Case]
1) Go to the greeter.
2) Press F10.
3) Press Down and Enter to select "Shut Down"
4) Try to press tab, or left and right, to select the buttons in the dialog that pops up

[Regression Potential]
A potential fix may cause problems restoring focus to the user list after the dialog disappears. Or maybe issues with the onscreen keyboard staying on top of the screen as we move focus around.

Thank you for your bug report, what greeter do you use? the gtk one or the unity one?

The unity one. I am still to check on the GTK one.

Actually, I would say both -- the description states lightdm-gtk-greeter is installed (so this was the environment I checked), and I just repeated it under the unity greeter.

I'm fairly sure that fixing this will also fix this one:

#933990 Unable to confirm shutdown using only keyboard

Since that dialog is tab-able in normal unity, I think it has problems due to focus.

This bug was fixed in the package unity-greeter - 0.2.8-0ubuntu1.3

unity-greeter (0.2.8-0ubuntu1.3) precise-proposed; urgency=low

  * debian/patches/fix-focus.patch:
    - Backport better keyboard focus handling from upstream as new windows
      appear and disappear. This fixes keyboard navigation in dialogs
      (LP: #986289) and the onboard keyboard not showing up on startup
      if it was enabled before (LP: #1051946)

There is still an underlying issue of "discover-ability" here and it fails, in my view, to be acceptable for a disabled user:

(1) Why does the tab key not cycle to the shutdown menu? Where exactly will a user, faced with the log-in screen, find out that the 'F10' key opens that menu?

(2) The tab key only cycles between the log-in method (e.g. Gnome, Unity, etc, and not the user list) and the entry window for the current account's password. How would a keyboard-only user change account?

Paul Crawford (psc-sat) wrote :

OK, I just discovered that the up & down arrow keys cycle the user accounts, but they do not cycle the log-in method! For that you need to use the tab key!

How do you get access to the accessibility drop-down menu on the to bar?

Same for the keyboard/language selection?

Also why no 'F1' for help on any of this? If it were obvious/discoverable using the tab key that would not be needed, but there seems to be a non-obvious mix of methods and some I have not been able to discover yet (as noted above).
