Scroll wheel uses inverted logic to switch between applications/windows in the switcher

  * == Problem == Lockscreen capslock detection doesn't work well with
    remapped capslocks == Fix == Use gdk keymap to get the state of the
    caps lock. (LP: #1347735)

  * PlacesOverlayVScrollBar and VScrollBarOverlayWindow: add support for
    scaling Add a new ScrollView class to create ScrollViews with an
    OverlayScrollbar and with scaling support. Using them in dash Scopes
    and Previews. (LP: #1340996)
  * LockScreenShield: Add GrabScreen function and retry to make sure we
    really get grab It might happen that the grab is not possible
    because the PluginAdapter::IsScreenGrabbed request has still not
    being fully processed, and thus nux is not able to grab the
    pointer/keyboard. By doing this we instead try to grab the screen,
    and if this is not happening, we wait a little until we don't get
    the ungrab event. In this way, if we eventually get the grab, all
    will work as expected. Otherwise, we cancel the lock request (very
    unlikely to happen). (LP: #1349128)
  * PlacesOverlayVScrollBar: redirect the mouse wheel scroll events
    coming from the thumb to the scrollview This will make the
    scrollview to handle then and perform the same scrolling action it
    would do otherwise. (LP: #1340992)
  * This has a "soft" dependency on lp:~3v1n0/nux/horizontal-scroll-
    delta/+merge/227070, this means that this code would just work as it
    used to do (except for the SwitcerView fix) if that nux branch is
    not used, while it will support correctly horizontal scroll events
    when both the branches are used. (LP: #1342208)

unity_7.2.3+14.04.20140826-0ubuntu1.debdiff

Hello Marco, or anyone else affected,

Accepted unity into trusty-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/unity/7.2.3+14.04.20140826-0ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

In order to verify this fix in trusty, you also need an update version of nux that is about to land.

So please, don't set this as verification-failure, until all the pieces are on proposed.

All the fixes needed to verify this bug are now in proposed, so please give a try to them and report the results!

I only checked vertical scroll because I don't have a mouse with horizontal scroll wheel.

I am confused about the expected behaviour.

The current description says that vertical scrolling has not been touched, but the listed expected behaviour is different from the behaviour under Impact.

What I expect, and what feels naturally correct to me is:
- Scrolling down, moves to the previous
- Scrolling up, moves to the next
- Scrolling left, moves to the previous
- Scrolling right, moves to the next

You can also verify horizontal scrolling by using a touchpad, scrolling Up should move to the previous, while Down to the next.

That's the same behavior that also Gtk has.

Hmm, Mathew is right, the SRU regression potential says vertical has not been touched, but it certainly has. I will follow up with Marco on what the intended behavior is supposed to be...

So, although I don't completely agree with the new vertical scrolling behavior in the Switcher, I don't think we should block the SRU on this since this is how Utopic now behaves. I think I will enter a new bug report about the behavior not being quite what is expected and then flesh that out. If we decide to switch the behavior back, then we will get it into another SRU. That said, marking this verification-done.

Oh, I did verify the horizontal scrolling now works as expected, which is the bigger issue here.

  * Remove cross fade effect during lock/unlocking. A simple fading
    works just fine. (LP: #1312107)
  * Manually emit nux::Area::geometry_changed beucase nux can fail to
    emit it. (LP: #1292391)

  [ Pawel Szubert ]
  * Reduce the scope of the kill command when restarting Compiz.

  [ Marco Trevisan (Treviño) ]
  * LockScreenAcceleratorController: do ther configured action on power
    special keys press. We finally can suspend, shutdown, hibernate or
    start the screensaver when the screen is locked, using the Suspend,
    Sleep, Hibernate and PowerOff hardware keys. Also the Shutdown
    dialog doesn't allow now to lock the session if it is not allowed by
    settings. (LP: #1306211) (LP: #1320051) (LP: #1320071)
  * Previews: scale the dash preview contents to match current monitor
    scaling. Improved also the scaling of search-bar, spinner, categories
    and many other components. (LP: #1339629)
  * FilterWidgets: add support for scaling (LP: #1340171)
  * OverlayRendering: correctly scale the overlays borders and edges to
    match settings. DashStyle has been modified to return smart pointers
    of textures that are loaded depending on the scale level. The cache
    will make sure that we don't duplicate the textures and that they
    get removed when not needed anymore. Also thanks to this the
    SearchBarSpinner textures (and the other spinners as well) uses the
    SVGs scaled at the proper size (I desgined a new SVG for the
    magnifier, as we only had a PNG). (LP: #1283415) (LP: #1340394)
  * Hud: scale to match current DPI settings for monitor. (LP: #1340477)

The verification of the Stable Release Update for unity has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

Christopher Townsend, did you file a bug about the change is vertical scroll behaviour introduced by this bug?

I don't thinkit's abug. Scrolling down should move to the next element, while scrolling up to the previous. As it is now.

It seems wrong to me, because when you scroll down over the sound indicator, which was also got an update at the same time in bug #1342731, the cursor moves left. So it should move left when scrolling down over the switcher.

Also there's a chance that this behaviour change was a mistake, since it was back-ported in an SRU, and the Regression Potential explicitly said, "Vertical scrolling code has not been touched by the change, so there's no possibility to regress in this sense."
