[Bug 741869] Re: Unity/compiz intercepts Super and Alt keypresses from grabbed windows like VMs.

 

This bug was fixed in the package unity -
7.2.0+14.10.20140512.4-0ubuntu1

---------------
unity (7.2.0+14.10.20140512.4-0ubuntu1) utopic; urgency=low

  [ Stephen M. Webb ]
  * lockscreen/LockScreenAccelerators.h: added required header for
    std:vector definition
  * disabled precompiled headers on arm64 Ubuntu package builds (LP:
    #1317276)

  [ Brandon Schaefer ]
  * Set the max width, so our static text wraps. So we don't end up
    rendering text out of the view area. (LP: #1312749)

  [ Marco Trevisan (Treviño) ]
  * UnityScreen: toggle activation of all the unity compiz actions when
    locking the screen Also, make sure that the lockscreen views are
    treated as "always-on-front" windows by nux (and this applies to
    both visibility and events).
  * PanelService: emit an invalid EntryActivated signal if the menu
    hasn't actually been shown In addition, if the menu is not visible
    after the first popup call, try to show a menu without keyboard
    focus. This will make possible to see menus also when there's a key-
    grab (although they will be without keyboard support). Finally,
    reset the menu state, if that failed.
  * UnityScreen: always paint the lockscreen above, just add menu and
    onboard as exceptions Some code cleanup, factorizing similar code.
    (LP: #1313280)
  * UnityScreen: don't try to show Dash/Hud if the screen is grabbed
    Also move the dash opening out from LauncherController, and get rid
    of UBus as first initialization source, as it can only slow things
    down here. (LP: #741869)
  * PluginAdapter: make sure we don't try to call an invalid
    initiate/terminate callback function (LP: #1221673)
  * DebugDBusInterface: match properties if they are in the AP array
    form [<type>, <value>] (LP: #1307748)

  [ William Hua ]
  * Add proper support for modifier-only shortcuts on the lock screen.
    (LP: #1291461)

  [ Jinkyu Yi ]
  * Dash: Fix problem at checking blacklisted unicode range (LP:
    #1251193)

  [ Andrea Azzarone ]
  * Add a warning in the session dialog if other sessions are still
    open. (LP: #1281058)

Bug description:
  [Impact]
  After upgrading from Maverick to Natty, I can no longer use the Super (windows) key in Virtual Machine Manager. Previously, as long as I had the Virtual Machine Manager console window in the foreground, I could press the Super key and the start menu would pop up. Since upgrading to Natty, this no longer works, and the search box appears in the upper left.

  Also see bug #934921

  [Test Case]
  (1) Install virt-manager and qemu-system, create and boot a virtual machine
  (2) while in the virtual machine, press the Super key
  Expected Result: the super key acts inside the VM
  Actual Result: the super key acts in the host and the Unity Dash is displayed

  [regression Potential]
  This patch plays with key grabs and ungrabs:  the most likely potential for regression is (a) the existing grabs continue and no fix obtains or (2) the grab is not resumed when returning control from the VM and the Super key does not invoke the Unity Dash.
