Bug 472587

I also hacked the Clock component in /usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/LockScreenUi.qml to set the visible property to always `false` to hide the clock from the lock screen.

There is an option for this in System Settings > Workspace Behavior > Screen Locking.

As noted in the first comment, the existing configuration option has no effect on the login screen before logging in or starting to type on the lock screen. I don't know what the point of the existing option is or if it's really worthwhile to have it there. I suggest replacing it with a simple boolean toggle to hide the clock from both the login screen and lock screen.

After updating to KDE 6, the file /usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/LockScreenUi.qml is still there for the lock screen, but the file that needs editing for the login screen has moved to /usr/share/sddm/themes/breeze/Main.qml. In both cases, set the `visible` property to always `false` for the clock.

I would like a proper solution to this that doesn't require me hacking QML files after package updates. SDDM is still around in KDE 6.0, but looking at https://invent.kde.org/plasma/plasma-desktop/-/issues/91 it seems its future in KDE is still unclear? In the meantime, changing the existing "Clock: Keep visible when unlocking prompt disappears" to a simple boolean toggle to show the clock on the lock screen could be done regardless of whatever happens with the display manager.

Use simple toggle to hide/show clock on lock screen

Part of https://invent.kde.org/plasma/plasma-desktop/-/issues/133.

This replaces the existing option "Clock: Keep visible when
unlocking prompt disappears" with a simple toggle that controls
whether the clock is always or never shown on the lock screen.

From the discussion when the old option was implemented,
(https://phabricator.kde.org/D24893) the use case for the old
option was for users who want an unobstructed view of the lock
screen background. This use case can still be satisfied by the new
option, and perhaps the simplicity of the new option will make it
easier to discover, as the old description in the UI was rather
awkward.

The difference with the new option is that it does not
matter whether the user is currently typing their password. With
the old option, the clock would still be shown when the user moved
the mouse or started typing, which didn't give users a choice to
not see a clock at all.
FIXED-IN: 6.2.0

It is no longer used since changing to a simple binary preference
for showing or hiding the clock.

Add option to hide clock in Breeze theme

Closes https://invent.kde.org/plasma/plasma-desktop/-/issues/133.

Requires https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/2366

M  +16   -5    src/themesmodel.cpp

Note that the GUI for configuring hiding the clock from the login screen will be in 6.3, not 6.2. In 6.2, manually editing the SDDM theme's theme.conf.user file to change `showClock = true` to `showClock = false` should hide the clock.
