Ultimately, we want to add support for GDM's new ChoiceList
PAM extension. That extension allows PAM modules to present
a list of choices to the user. Before we can support that
extension, however, we need to have a list control in the
login-screen/unlock screen. This commit adds that control.
For the most part, it's a copy-and-paste of the gdm userlist,
but with less features. It lacks API specific to the users,
lacks the built in timed login indicator, etc. It does feature
a label heading.

It's not visible because it's covered by the actual wallpaper, so
not rendering it eliminates most of the render time for
`workspace-background`, without changing its appearance.
When animating the overview by tapping Super, this reduces the

Now that we made window previews overlap the edges of the wallpaper
underneath them, the app icons of those windows are getting quite close
to the dash and there is almost no more spacing.
Let's make it look a little bit better and slightly increase the

away from the dash.

At the moment the timed login feature is implemented in the user list.
If there's no user list, we don't show the indicator anywhere and

With the introduction of the transparent panel in the overview, we
started making the panel text/icon color slightly brighter in the
overview and on the lockscreen to ensure best contrast. Now
unfortunately, setting the text color incurred a relayout of the
underlying ClutterText actor (fixed with
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1750), and
setting the icon color causes the icon texture to get regenerated
(fixed with
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/932).
Regenerating the icon texture will replace the icon actor, which also
causes a relayout.
This relayout of the panel has been measured to add at least 1
millisecond (the numbers fluctuated a lot) to about 5 ms it takes to
layout the first frame when showing the overview.
Since https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/932 is
unlikely to land this cycle, this commit proposes a different solution:
Simply don't use a different color for text in the overview. To avoid
issues with contrast in the overview, make the default color slightly
brighter and change it from #ccc to #ddd.

Use a bit less margin at the top and add some margin at the bottom of

The Dash currently has a horizontal margin and a top margin applied. The
horizontal margin isn't necessary since there already is a horizontal
padding applied, and the top margin is a bit large, since the
ControlsLayout enforces a spacing between the different containers
already, so slightly decrease the margin-top here.

Depending on the available horizontal space, we may want to manipulate
the icon grid and scroll view spacing to result in an optimal layout
that has space left to preview prev/next pages.
The main change here is that, when adapting to the available size, the
space given to a page does not necessarily match the available space,
as we need to be able to show more than one page at a time.
With this decoupling of available and page sizes in place, we now know
how much space there is available in order to extend the padding between
pages, or the fade effect applied to the previewed pages.
Underneath, we rely a bit less on hardcoded CSS paddings, and a bit more
on the StScrollView::content-padding property.
All put together, gives us proper space management from ultra-wide
displays, to display ratios that are close to the optimal grid ratio.

When DnDing an icon, we show both previous/next page, and optionally
a "placeholder" actor to allow creating new pages. These sides on the
scrollview are drop targets themselves, allowing to drop an app onto
the next/prev page without further navigation.
Still, preserve the checks to maybe switch to prev/next page without
finishing the DnD operation, for finer grained operations.

Add the necessary animations to slide in the icons in the previous/next

can animate independently.

We want to show left/right side pages during navigation, also in

The workspace minimap is much less prominent than the old workspace
switcher, and serves primarily as an indicator.
That means that duplicating it on secondary monitors (if workspaces

every monitor.

A small mistake snuck in right before landing the previous commit and

According to the GNOME 40 mockups, add a box-shadow to the workspace

the rounded corners of the wallpaper, we also need to tell St to use a
border-radius and clip the background-color painting using a rounded
path.

Resource icons are added to the fallback icon theme, so they won't
get used if a matching icon is found in the configured theme.
That includes fallback names, so Adwaita's "window-close-symbolic"
takes precedence over "window-close-24-symbolic" in hicolor.
Fix this by using a custom name for a custom icon.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1640>
Adwaita uses ui/ for the corresponding icon, but GTK treats icons
from a resource path as part of the hicolor theme that doesn't
have such a subdir. And as GTK determines subdirs by enumerating
the theme directory, any subdirs that only exist in the resource
are ignored, whoops.
Make sure the icon can be found by moving it to a standard subdir.

When we display the hint string for e.g. (or swipe finger), the login

The code previously was using CSS to define row/column spacing and
padding which was combined with a subicon size computed in code relative
to the requested icon size.
In smaller icon sizes it was possible for the CSS spacing+padding + the
size of the two subicons to exceed the requested icon size. This then
would lead to the label being pushed down for app folders compared to
other icons.
Another more severe issue caused by this would happen if the first item
in an icon grid was an app folder. Then the calculation for the maximum
allowed icon size could be off, leading to all icons in the grid
becoming smaller than actually necessary.
This commit changes this to use homogeneous row and column layouts to
evenly distribute the remaining spacing instead of using a fixed CSS
value.

The overview is using a heavily darkened background image nowadays.
Since the contrast provided by this is always good enough, this makes it
possible to always have a fully transparent panel while showing the
overview.
So change the theme to always make the panel fully transparent while the
overview is shown. The duration of the animation for that is 250ms
because that's the duration of the show and hide animation of the
overview.
Also add special handling for the high-contrast theme, where we always
make the panel opaque.

The current way of indicating focus of elements in the panel does not
work very well with a fully-transparent panel, a line at the bottom of
the panel doesn't make too much sense if there is no real panel, but
only the text and icons.
To make the indicators look better in this case, switch to a pill-shaped
background color to indicate the focus of items in the panel.
For this to look good, there has to be a small black border above and
below the background, this also requires increasing the height of the
panel (from 1.86em to 2.2em) for visual purposes.
Also, since we now no longer need to color the lower bottom of the
panel, we can remove the custom drawing code for the border of the
panels corner, so do that.

The activities button doesn't have an icon, which makes its horizontal
padding appear a bit smaller than the padding of most other items in the
panel.
We're going to indicate hover and focus of items in the panel using a

will get more visible. So give the activities button a special treatment
and slightly increase its padding to make sure the new indicator will
look good.

Recent commit [1] added a strong light border around user avatar
icons, in accordance with design mockups.
As a probably unintentional side-effect, the border was also added
around the symbolic fallback icon, which is displayed whenever the
user avatar is not available. This doesn't work well with the current
design, as the strong border makes the subtle fallback icon
background indistinguishable. Additionally, it doesn't match the
design mockups for the symbolic avatar icon [2].
Correct this by adding a style class for when avatar image is used,
and apply the border only for that case.

The default sizing for user-icon style was not defined in the theme,
but it simply used the default Avatar iconSize from UserWidget.js.
This didn't work with the current fallback avatar styling (i.e. when
the avatar icon is not set for an user account, and a symbolic icon
is displayed in its place), as the fallback StIcon was not scaled
to align inside the circle shaped user-icon properly.
Define the user-icon and corrected fallback StIcon sizes in the
stylesheet to correct this. The default 64px user-icon size is based
on default UserWidget.Avatar iconSize. The sizing for the StIcon is
taken from `.user-widget.horizontal .user-icon` styling, which uses
the same base icon-size.
Additionally, the special `.user-widget.horizontal .user-icon`
styling is removed, as it is now redundant.

Screen magnification is the compositor's business, not that of "random"
unprivileged tools. And for cases where a more specialised behavior is
wanted, an extension likely does a better job than a consumer of the
D-Bus API.
In addition to that, exporting the interface has been broken for an
unknown time, because the object that holds the implementation isn't
referenced and thus ends up being garbage collected, whoops.
And last but not least, this gets rid of the last public D-Bus name
that isn't clearly in the system namespace (org.gnome.Shell,
org.gnome.Mutter, org.gtk).

Move the GNOME shell service file adapation for x11/wayland into the
target/service files. This means that the session definition can simply
pull in org.gnome.Shell.target, without having to care about whether it
is starting an X11 or wayland session.
Note that this currently requires fork'ing to do the test. This will
however not be needed in the long term when ConditionEnvironment becomes
available (see https://github.com/systemd/systemd/pull/15817).
We technically do not need to use template units. But doing so means
that the unit can be translated to the app id more easily (though it is
not yet completely clear how this should look like in the long term).

This is the key that will be used to store the pages and the icons in
each page. The idea is that we we store an a{sv} variant for each page.
This variant will contain <icon id> → array of properties, where we
can store arbitrary data for each icon. The expected output of this
key is:
[
{
'polari.desktop': <{ 'position': 0 }>,
'epiphany.deskop': <{ 'position': 1 }>,
},
{
'telegram.desktop': <{ 'position': 2 }>,
'builder.desktop': <{ 'position': 0 }>,
'gitg.desktop': <{ 'position': 1 }>,
}

The toplevel array is sorted, and pages of the grid always show in the
order they are stored.

While GtkIconTheme does look up icons in the toplevel icons resource
path, it will only use them as ultimate fallback. That is, if the
icon theme (or the hicolor fallback) include a "keyboard" icon, it
will be used over the "keyboard-enter-symbolic" icon in the resource.
Moving the icons to appropriate subdirectories gives them higher
priority than the fallback names, and thus fixes the issue.

Switch to the new WorkspaceLayout layout manager to allocate the window
clones of the overview properly using Clutters layouting mechanisms.
Since we now no longer make use of the fullGeometry, we can remove the
setFullGeometry() function from the Workspace class. Also we can stop
setting the actualGeometry on the Workspaces and WorkspaceViews and
instead just set the fixed position and size of the views to their
full or actual geometry. This also has the benefit that we no longer
have to set a custom clip, but can simply enable clip_to_allocation.
The geometry needs to be set inside a BEFORE_REDRAW later because
_updateWorkspacesActualGeometry() is called from a notify::allocation
handler.
This isn't doing any animations when showing/hiding the overview yet,
we'll add that in the next commit.

Using CSS to center the title actor on the border is a bit ugly, because
it requires the CSS to match the calculations used in chromeHeights().

Instead use an invisible actor that spans between the horizontal and

The Frequent apps grid has a few problems:
* On a fresh install there would be no history of app usage so the
applications shown in the grid have no relevance it takes time
to be useful instead of being useful from the start;
* The grid has far too many items in it to be relevant; 24 apps is
well beyond the average use case as most people don't frequently
use that many, so it gets populated with several apps that are
single use (hello xterm);
* The position of items in the grid are always changing based on an
unknown frequency metric (and not by user-intended input) which
makes it a poor way to quickly launch apps as one would have to
constantly learn the positions of the items in the grid;
* Having two app grids is a bit superfluous and needlessly complicates
the app launching navigation: you have to spend time checking the
frequent grid and if it's not there you have to switch over to another
grid and find the app you need in there it's not straightforward.
Remove the Frequent tab and simplify the related code.
