[Bug 1320438] Re: Unity launcher auto hide fails on screen unlock using "Super+L"

 

This bug was fixed in the package unity - 7.2.2+14.04.20140714-0ubuntu1

---------------
unity (7.2.2+14.04.20140714-0ubuntu1) trusty; urgency=medium

  [ Alfred Neumayer ]
  * Restore the launcher position by reversing the animation and
    unsetting the DND_PUSHED_OFF quirk. (LP: #1304882)

  [ Brandon Schaefer ]
  * TextInput: move the warning icon inside the input field, render it
    white (LP: #1307738)
  * ShutdownView: Scale up the Buttons and Text plus Borders of the
    UnityWindowView. (LP: #1308323)
  * Lockscreen warning icon needs a tooltip to say what the warning is
    about! (LP: #1308288)

  [ Marco Trevisan (Treviño) ]
  * UnityScreen: always paint the lockscreen above, just add menu and
    onboard as exceptions Some code cleanup, factorizing similar code.
    (LP: #1313280)
  * ApplicationLauncherIcon: Focus and, in case, Spread the windows on
    DnD After 1 second that an user is over an icon, that icon should
    focus the relative application and Spread its windows if it has more
    than one opened. Correctly handle the DnD scale in launcher, and
    apply glow to the icon under pointer. (LP: #607796)
  * ShutdownView: Scale up the Buttons and Text plus Borders of the
    UnityWindowView. (LP: #1308323)
  * SwitcherView: use RawPixel's for the size values and convert them to
    match current scaling (LP: #1317348)
  * PluginAdapter: try to grab the screen to make sure that the screen
    is not grabbed FocusIn event with NotifyGrab mode is not always
    triggered by X when a window takes the grab, then we need to ensure
    that there's no grab by trying to get one. We only care about
    keyboard here, since pointer grabs don't affect us in general.
    (LP: #741869)
  * ShortcutView: use RawPixel's for the size values and convert them to
    match current scaling Plus dinamically allocate horizontal space,
    not to cut the text. (LP: #924840)

  [ Chris Townsend ]
  * Fix issue where scaling the edge illumination up and down with the
    size of the Launcher icons would cause the illumination border to be
    offset and smaller than the icon. (LP: #1309739)
  * Fix issue where the number of Launcher icon pips are not always
    properly updated when a new window of an already running application
    is opened. (LP: #1283775)
  * Fix issue where the Panel shadow would get drawn over drop down
    windows in full screen windows. (LP: #1316005)
  * Bump upstream release to 7.2.2.

  [ Andrea Azzarone ]
  * Clear the clipboard when locking the screen. (LP: #1308911)
  * Disable switcher gestures if screen is locked. Fixed a regression.
    (LP: #1321043)
  * Pass the correct options to showLauncherKeyTerminate in
    UnityScreen::OnLockScreen (LP: #1320438)
  * Fix skype indicator blinking. (LP: #1310200)
  * Add a warning in the session dialog if other sessions are still
    open. (LP: #1281058)

  [ Ubuntu daily release ]
  * New rebuild forced

Title:
  Unity launcher auto hide fails on screen unlock using "Super+L"

Status in Unity:
  Fix Released
Status in Unity 7.2 series:
  In Progress
Status in “unity” package in Ubuntu:
  Fix Released
Status in “unity” source package in Trusty:
  Fix Released

Bug description:
  [Impact]
  The launcher is not properly auto-hidden when locking the screen using Super+L keybinding

  [Test case]
  1. From Unity Control Center -> Appearance -> Behavior enable the launcher auto-hiding
  2. Press Super+L in order to lock the screen
  3. Unlock the screen, now the launcher should be hidden

  [Regression potential]
  Unity might hang when locking the screen (due to the sync compiz call to screen->getCurrentTime() that in some very-rare cases in the past demonstrated to be prone to some race conditions). No case has been recorded so far in this scenario, though.

  -----

  I use a Compaq cq40 running Trusty. If I lock the screen using the
  "Super+L" hotkey, upon unlocking the unity launcher bar appears on the
  screen. I'll have to press "Super" key twice to hide it again (Hitting
  once brings up the dash home, hitting once again hides the launcher).
  This is not observed if use the "Ctrl+Alt+L" hotkey. The following are
  the system details:

  Auto hide is enabled for unity launcher. Is there a way to resolve
  this annoying behaviour? Thanks!
