Support both left and right mouse button activating elements

[Robin Sheat]

I use the mouse left handed. When I do something that pops up a dialogue, say telling the computer to shut down from the login screen, the buttons on the dialogue don't respond to the primary mouse button (the right one in this case.) I think the menus to bring up that dialogue are ambidextrous (well, I didn't get button confusion bringing it up, anyway.)

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

Not sure that should be a configuration, you only need to click on the greeter, the old gdm (pre rewrite), was just reacting to both left and right click the same way to avoid those issues

[Robin Sheat (eythian)]

It doesn't make a lot of sense to be a configuration really, you don't know if the person who sat down at the computer just now is right or left handed anyway.

Oh, that's clever. I'd never noticed it did that. I've opened a design task on this to see what they think.

@robert-ancell; let's briefly discuss this bug when we meet at UDS in two weeks time.

[Adam Dingle (adam-yorba)]

Currently it's possible to click most buttons in unity-greeter using either the left or right mouse button. But some still accept only a left click:

- the buttons in the shutdown dialog (as noted above)
- the button that lets you select a login session (e.g. either GNOME or Ubuntu)

[Mikel Ward (mikelward)]

Still an issue in Trusty.

Why does the last update say "no longer affects:unity-greeter?"
