[Bug 2007614] Re: [SRU] Change to plasma causes login splash screen defaults to propogate differently

[Erich Eickmeyer]

Upon testing, I was able to verify Aaron's findings that this is a
problem on the ISO image itself as well. As such, I changed the test
case above. However, I was able to verify that ubuntustudio-default-
settings 22.04.26.3 does, indeed, fix the issue.

* Run candidate .iso image in a VM
  - Notice incorrect login splash.
* Enable proposed repository.
* Install ubuntustudio-default-settings 22.04.26.3
* Logout
* Login
  - Notice correct login splash (attached screenshot)

This *will* require a respin of the Ubuntu Studio 22.04.2 candidate .iso
image.

** Description changed:

  [ Impact ]
  
  It is questionable whether or not this is a regression because this is
  caused by point updates to plasma, but default settings are now being
  set in ~/.config/kdedefaults based on the default theme which may or may
  not include the login splash.
  
  The splash is included in the look-and-feel (global) theme "Ubuntu
  Studio" (org.ubuntustudio.desktop) but the default look-and-feel theme
  is "Ubuntu Studio Dark" (org.ubuntustudio-dark.desktop). Beginning in
  one of the point releases of plasma 5.24, the ~/.config/kdedefaults
  started setting ~/.config/kdedefaults/ksplashrc to point to the default
  look-and-feel theme's splash as opposed to the already prescribed splash
  as set in ksplashrc in the $XDG_CONF_DIRS path. Since org.ubuntustudio-
  dark.desktop does not have a splash, this returns an empty value after
  install and the login splash reverts to the default plasma login splash
  as opposed to the Ubuntu Studio branded splash.
  
  The reason this is questionable as to if this is a regression in Plasma
  is that it may be by design; that a splash screen is now expected in the
  default theme. However, this doesn't appear to be the case in later
  versions, e.g. Plasma 5.26 and Plasma 5.27, although the method for
  setting defaults has changed in these later versions to include ways to
  set for Wayland.
  
  [ Test Case ]
  
  * Download and run the Ubuntu Studio 22.04 Jammy Daily .iso image
-   - Splash will be the Ubuntu Studio splash
- * Install (either VM or actual hardware, doesn't matter)
- * Upon login, splash would be the default KDE Plasma splash. This is not desired.
+   - Splash will be the default Plasma splash and NOT the Ubuntu Studio splash. This is not desired.
  
  [ What Could Go Wrong ]
  
  * There will be *two* entries for the same splash theme, one for Ubuntu
  Studio and one for Ubuntu Studio Dark. Without removing the one that
  says "Ubuntu Studio" or redoing the entire defaults to make the dark
  theme "Ubuntu Studio" and the lighter one "Ubuntu Studio Light"
  considering there's already an "Ubuntu Studio Light", this will not be
  possible to avoid.
