[Dx-packages] [Bug 1300722] Re: hud-service is eating up 100% of one of my CPUs in a poll loop

[Benjamin Brummernhenrich]

This is my first time using Launchpad so please tell me if I'm doing
anything wrong, leaving something out or shouldn't have posted:

The culprit is Firefox in my case too. If I close it, everything returns
to normal. HOWEVER, on my machine, this only affects my wife's user
account , not my own. If it helps I will provide logs for each of the
two users the next time it occurs.

[Dx-packages] [Bug 1290785] Re: Users with UID > 60000 are invisible in login and Settings->User unless /etc/login.defs updated

[Robert Ancell]

If you have an account which is not showing in the greeter using Ubuntu 14.10 
with the updated packages please provide the following information on the user:
$ gdbus call --system --dest org.freedesktop.Accounts --object-path 
/org/freedesktop/Accounts/User1000 --method 
org.freedesktop.DBus.Properties.GetAll org.freedesktop.Accounts.User

(replace 1000 with the UID)

LightDM shouldn't hide any users so hopefully one of the user properties
should indicate why it isn't being shown.

Bug description:
  [Impact]
  Users of Ubuntu 14.04 LTS with UID > 6 will not show in the greeter or 
system settings without editing UID_MAX in /etc/login.defs. This was not 
required in 12.04 LTS. In 12.04 LTS users were only hidden if they had UID < 
UID_MIN. In 13.10 this was changed to UID < UID_MIN or UID > UID_MAX.

  [Test Case]
  1. Create a user with a UID > UID_MAX:
  $ adduser --uid 60001 big-uid
  2. Restart system
  Expected result:
  "big-uid" is shown in the greeter. Once logged in "big-uid" is shown in 
system settings.
  Observed result:
  "big-uid" is not shown in the greeter (14.04 LTS, 14.10)
  "big-uid" is not shown in system settings (13.10, 14.04LTS, 14.10)

  [Regression Potential]
  This could cause users that were previously hidden to be shown. This seems 
unlikely to be a problem as all system created user accounts are less than 
UID_MIN and there doesn't seem be a convention to use accounts > UID_MAX for 
this case.

[Dx-packages] [Bug 974480] Re: Notification area whitelist is obsolete

[Dmitry "Divius" Tantsur]

Folks, all words were said and you already know how your users hate you
for this decision. You already know that users of Cryptkeeper, Audacious
and many more have to rely on PPA because you broke what was working
without any (even theoretical) advantage for them. But I'm soory
frustrated after 12.04 -> 14.04 upgrade, that I'm still writing this
comment.

Of course, I don't pay you money and I can't demand anything. I must eat
what I was given and shut up. You clearly showed me this. Thank you for
opening my eyes.

Regards,
former Ubuntu fan.

  Mark has asked us to consider retiring the notification area whitelist
  for 12.10. The application indicator system has been in place for two
  years now, which should be long enough for applications to adopt it.

  If the whitelist was retired, Java and Wine would be hard-coded as the
  only software still able to use the menu bar as if it was a
  notification area, because their developers don't necessarily know
  that Ubuntu even exists.

[Aaron Gerber]

I really don't think the status is correct.  The fix was only released
for the beta release of Ubuntu.  Shouldn't bug fixes also be applied to
current stable releases?

[Dx-packages] [Bug 732653] Re: Menus are hidden by default

[Adnan]

Personally i am only bothered by the hiding menus once the window is
maximized. Then when i click on the title bar, i either get the launcher
icons or one of the menu items.

I dont understand why there is no option to always enable menus? I mean
in mozilla firefox we are seeing the "page title" on the main menu bar
and this information is already present on the current open tab (hover
over tab to see page title) , so its duplicate information.

Why not just put the menus instead of the "page title" there?

Bug description:
  Ubuntu 11.04, Ubuntu 11.10, Ubuntu 12.04

  1. Log in to Unity, and try to connect to a server: "File" > "Connect to 
Server".
  2. Launch Firefox, and try to select an item from the "Bookmarks" menu.

  What happens:

  1. The "File" menu, and the rest of Nautilus's menus, are hidden by default.
  - Unless you mouse over it, the menu bar is blank.
  - When you mouse over it, the menus appear.

  2. The "Bookmarks" menu, and the rest of Firefox's menus, are hidden by 
default.
  - Unless you mouse over it, the menu bar contains only the text "Firefox Web 
Browser", which isn't useful at all (especially, but not only, since the real 
name of the application -- "Mozilla Firefox" -- is already present in the 
window title bar).
  - When you mouse over it, the menus appear, partly but not completely 
replacing the previous text: "Firefox W File Edit View…".

  What should happen: Menus should be visible by default, so that you
  can know that they exist without scrubbing the screen, and so that you
  can see where a menu is each time you aim for it.

  The current behavior has led some people (including, this week, one of
  my design colleagues) to conclude that Ubuntu applications don't have
  menus when they do. For example
  : "One of the most handy menu entries in
  GNOME (for me at least) is the Connect to Server entry in the Places
  menu. This allows the user to connect to nearly any type of server
  quickly and easily. The user can even connect to a Windows Share from
  here. In Unity - you won’t find that. In fact, you will be hard
  pressed to find any means to connect to a server in Ubuntu Unity."

  In bug 720424, Jono Bacon reported that "when we did some developer
  tools usability testing last week and on some other occasions when I
  have had someone use Unity, I have noticed that some folks don't
  realize there is a menu there as it is not visible."

  This was confirmed by usability testing of Ubuntu 11.04, where 2 out
  of the 10 people who needed to use a menu item could not find the
  menus at all -- and of the 8 who did find them, 7 did so only when the
  window was maximized. https://lists.ubuntu.com/archives/ubuntu-
  desktop/2011-April/002970.html (Usability testing results of Ubuntu
  11.10 or 12.04 have never been published, but this part of the design
  did not change.)

  Do not confuse this bug with bug 682788, which is about adding an
  option for visibility. Adding any options would not fix this bug,
  which is about menus being hidden *by default*.

  -
  Desired change:

  Implement the 'Enhanced Menu' project for 12.10. This project will
  address the issues described in this bug and also issues described in
  the duplicates of this bus. Note the 'official' bug that tracks the
  implementation of this project is bug #682788

  The following options will be added to 'System Settings/Appearance':

  ---
  Menus
  Location: Global/Local
  Visibility: Hidden/Always displayed
  ---

  More details to follow during the 12.10 cycle... ;-)

[Dx-packages] [Bug 1335582] [NEW] Scrolling in one desktop "touches" apps in another desktop

[Pedro Côrte-Real]

Public bug reported:

I've found a bug in how unity/compiz handles multiple desktops. Here are
the steps to reproduce it.

1) Setup four virtual desktops in a 2x2 configuration
2) On the top-left desktop setup a terminal window maximized to the left side 
(by dragging it to the left edge so it uses the left half of the screen)
3) On the top-right desktop open up firefox and maximize it
4) Navigate to a page that needs scrolling
5) Try to scroll by moving the scrollbar on the right of the screen

What happens is that the mouse pointer gets grabbed by the resize target
of the terminal window on the top-left screen.
