shutdown options window does not have focus

[Geoffroy Ménard]

[Impact]

In MATE session, logout and shutdown dialogs sometimes don't get the focus, and it's impossible to switch to them with Alt-Tab due to their design. One has to use the mouse to switch there. Using Ctrl-Alt-Tab can help as well, but I found out it doesn't work reliably in VirtualBox.

The fix for this issue is provided in the debdiffs attached to the report.

Would be nice to have the fix backported to all current Ubuntu releases (Xenial, Zesty and Artful). The bug is very annoying for users who rely on keyboard shortcuts to navigate the desktop. It also can be considered a11y issue.

[Test Case]

There are several ways to reproduce this issue. For me the most reliable one is to use keyboard shortcut to call the shutdown dialog:

- press Ctrl-Alt-Del, the shutdown dialog appears, and it's usually focused
- press Esc to dismiss the dialog
- press Ctrl-Alt-Del again, now the shutdown dialog will appear unfocused

Now you need to use the mouse or Ctrl-Alt-Tab to interact with the dialog.

[Regression Potential]

The fix just ensures that logout/shutdown dialogs will be always focused when they appear on the screen. It means the dialog's behavior is restored to what users expect. Nothing else is affected, so no chance for regressions.

[Original Description]

Whether called by the power button (if configured as "Ask user") or by clicking Quit in the menu, the shutdown options window does not have the focus. It also does not appear in the windows when using alt-tab, making it virtually impossible to shutdown without using the mouse/touchpad.

What version of Ubuntu MATE are using using?

[Etienne Papegnies (etienne-papegnies)]

I can reproduce this in Ubuntu MATE 16.04.3 with compton.
I can also reproduce on 17.10 with compton, but not all the time. Maybe some randomness here. I think the stacking of windows plays into this somehow, I can't reproduce if I have only one terminal window open.
The part about the window not being in the window list (alt-tab), that I can reproduce always, not sure if it's intended.

[Alexander Browne (elcste)]

I've noticed this too in 17.04 and 17.10 with compton plus marco and metacity. It does seem to happen less with only one window open, but after trying various of combinations of 1, 2 and 3 windows open of different apps, sometimes with windows minimized, it's not as simple as that :-/

Performed the same test in Xenial, Zesty and Artful:

- replaced local build of mate-session-manager package with -proposed version:
  - 1.12.2-1ubuntu0.1 from xenial-proposed in Xenial
  - 1.18.0-0ubuntu1.1 from zesty-proposed in Zesty
  - 1.18.1-2ubuntu2.1 from artful-proposed in Artful

- restarted MATE session
- invoked logout and shutdown dialogs several times via various methods (menu items, keyboard shortcuts, mate-session-save command-line tool)

All good, both logout and shutdown dialogs always have the focus after they appear.
