Description MountainX 2022-07-25 21:54:19 UTC

I am *never* seeing the clock on the lock screen

This issue was previously discussed in Bug 454074, but my issue is slightly different from that bug.

Plasma Workspace is installed from the "Extra" Arch Linux repo. All my files in /usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/ appear to be original and unmodified.

usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/LockOsd.qml
usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/LockScreen.qml
usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/LockScreenUi.qml
usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/MainBlock.qml
usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/MediaControls.qml
usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/NoPasswordUnlock.qml
usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/config.qml
usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/config.xml

All those files are owned by the plasma-workspace 5.25 package.

My theme is Breeze Dark. My Plasma Style is Breeze Dark. Splash Screen is Breeze.

The only non-standard components I'm using are:
1. Sugar Dark sddm login theme, but I have read that the login and lockscreen themes are independent.
2. the ClassiK application style, but this clock issue existed long before I ever install ClassiK.
3. Window Decorations are ClassiK.

# STEPS TO REPRODUCE

1. Use Breeze Dark theme
2. In System Settings > Workspace Behavior > Screen Locking > Configure, check the box: Show [x] Clock
3. Lock the screen and look to see Clock either when the auth prompt is visible or when it's not visible. In my case, no clock is ever shown.

Strangely, the issue is present on my laptop and desktop and another Arch Linux device too.

OBSERVED RESULT
Clock is not shown when the auth prompt is visible
Clock is not shown when the auth prompt is invisible

EXPECTED RESULT
I used to have a clock on the lock screen. It disappeared some time ago and I don't know why. Have been trying for a long time to get it back.

SOFTWARE/OS VERSIONS

KDE Plasma Version: 5.25

Hmm, none of those errors seem related to the clock. Do you have anything in ~/.local/share/plasma/desktoptheme/? If so, can you print the contents?

I do not have that folder. And inside ~/.local/share/plasma/, I only have:

That's really odd. Can you attach a screenshot of your lock screen when the auth prompt is visible, and a screenshot of your lock screen when the auth prompt disappears?

I can, but it is also very simple to describe it completely in text:

1. when the auth prompt is visible:

- upper left area of screen: nothing is displayed
- upper right area: nothing 
- lower left: keyboard icon with text description of my keyboard layout
- lower right: battery icon with percent charging text
- center, upper: user avatar with text of username below it
- center middle: text input box for password with ">" button to right.
- center lower: hibernate and suspend clickable icons
- background: my wallpaper

If I enable media controls in settings, they are visible. When I uncheck them (as they are currently), they are not visible.
Checking or unchecking the clock setting has no effect whatsoever.

2. when the auth prompt disappears:
- background: my wallpaper (exactly the same wallpaper as in #1)
Nothing else is shown at all.

Comment 6 Nate Graham 2022-07-27 15:18:39 UTC

How exceptionally strange. Nonetheless, could you attach at least the screenshot of your lock screen with the auth prompt visible? I want to make absolutely sure it (otherwise) looks how I would expect.

lock screen as requested

Comment 8 Nate Graham 2022-07-29 14:55:00 UTC

Yep, just as you described. Thanks.

I have no idea what could possibly cause this, unfortunately.

Comment 9 Nate Graham 2024-08-23 02:38:15 UTC

In Plasma 6.2 there's an explicit option to either always or never show the clock, which removed a bit of the conditional logic that might have been going wrong here. Let's assume it's fixed in Plasma 6.2. However, if after upgrading to Plasma 6.2, you can still reproduce the issue, please feel free to re-open this Bugzilla ticket. Thanks!
