New window decorations break middle click title bar

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

As previously reported on Bug #1282264, the middle click on the title bar still works when windows are maximised.

Hard to find but easy to patch :D.

It should be noted that this further breaks user configurability of click actions. But these settings seem to already be ignored in Unity lately with or without LIM.

Another thought about the patch, perhaps the function should explicitly return after a call to lower? Changing the "else if" button != 1 to just "if" would catch all cases and return just in case.

And a positive note about the "further breakage" - as is this does at least provide complete consistency with LIM vs. not and maximized vs not.

The attachment "Quick fix - Lower action is hardcoded in." seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

This bug was fixed in the package unity - 7.2.0+14.04.20140410.1-0ubuntu1

---------------
unity (7.2.0+14.04.20140410.1-0ubuntu1) trusty; urgency=low

  [ Sami Jaktholm ]
  * Shortcuts: Listen and react to view close requests. (LP: #1297842)

  [ Brandon Schaefer ]
  * When we detect caps lock, or caps lock is pressed, render a warning
    icon to show its on. (LP: #1291737)

  [ Marco Trevisan (Treviño) ]
  * DecorationsGrabEdge, PanelMenuView: perform proper WM action on
    clicks, based on user settings (LP: #1283849)

  [ Alfred Neumayer ]
  * Alt-Tab has always respected the alt-tab-bias-viewport setting, but
    the 3-finger gesture to switch between windows has not, even though
    it does the same thing. They should behave the same way depending on
    the CCSM setting. (LP: #1303060)
  * Launcher: Show and hide the launcher window OnDragUpdate() to fix
    the gesture animations (LP: #1303141)
  * If the dash has not been opened before, a 4 finger tap will result
    in a dash with no selected scope. Instead, set up the window and
    view of the dash by sending DASH_ABOUT_TO_SHOW (same happens when
    hovering the mouse pointer over the BFB icon) and open the home
    scope. (LP: #1303468)

  [ CI bot ]
  * LockScreen: add ability to show without fading in on some system
    calls Also, if locking is not enabled, calling Lock causes the
    screensaver to be initiated. Many cleanups and misc fixes. (LP:
    #1292575)

  [ William Hua ]
  * Enable sound buttons and input source switching under lock screen.

This was actually fixed in 7.2.0.

The middle click problem came back in Ubuntu 15.04.
(Also tried the daily-live "26-Mar iso 64bit")

I had a look into dconf-editor and unfortunately there's no way to set "lower" in /org/gnome/desktop/wm/preferences/action-middle-click-titlebar.

I thought the same thing, but you can set the middle click action to 'lower' via Unity Tweak Tool. I can't remember what section it was in though, possibly in Window Manager -> Additional.

Thank you very much Lem, it works with Unity Tweak Tool.

In the meantime I discovered that it works also running the following command:

$ dconf write /org/gnome/desktop/wm/preferences/action-middle-click-titlebar "'lower'"

It might sound crazy, but this is one of the most important feature to me!
Anyway, it would be nice to have the mid-click on the title bar working again by default :)
