KDM is obsolete, and SDDM bug reports are tracked at https://github.com/sddm/sddm. However this request is for the Breeze SDDM theme, so moving it there.

@Nate we've been putting anything that comes from plasma-workspace/lookandfeel here. That duristriction is a bit messy.

As for the bug:

The old lockscreen handled with the half opactiy black stripes, but this was explicitly removed in the new design which came from the VDG. A fix needs to come from there also.

Thanks, we're currently discussing this.

I solved the readability problem by moving the texts to the sliding semitransparent cover.

The lock screen has same problem: Bug 369676 - White lockscreen text's readability depends on background - https://bugs.kde.org/show_bug.cgi?id=369676

This problem goes away if there's a way to do custom theming. It would be nice to have the lockscreen to be in harmony with the login screen (SDDM).

A proposed new design that VDG is iterating on can be found in Bug 369676.

We won't be able to support arbitrary user-specified themes since the login screen has to be able to run independently of any individual user's settings, but we could at least make it consistent with the default lock screen look.

Could you tell what do you mean 'custom theming' ?

I have edited both the SDDM greeter and the lock screen.

Result is: From Breeze Slider 2 SDDM theme to Breeze Custom Lock.mp4 - https://youtu.be/rCDBdGe8va0

All components are available from the KDE store to custom the your system.

fade to blur when the login box appears

Summary:
for both lockscreen and login screen:

* display the wallpaper and the clock with a shadow by default
* at the first mouse or keyboard input, make the input fields appear
* the actual controls appear pretty fast
* the wallpaper starts to blur, desaturate and fade to darker
* after 10 seconds make the controls disappear again

* as soon as anything is written in the password field never fade out the controls
* if the virtual keyboard is open, never fade out the controls
* if anything is pushed on the stack, like "switch user", never fade the controls
* Esc clears the field and makes controls disappear (closing keyboard if needed)

the fade won't happen if the background is a simple color

FIXED-IN: 5.13

Depends on D12314

Recommended D11309 and D11308 to change the default wallpaper to plasma wallpaper

Test Plan: tested the behavior of all the above points
