Unfortunately it's not that simple. All legacy full-screen Plymouth themes are affected by this bug. In order to work correctly, the Plymouth theme is now relying on an existing parent theme as plymouth- theme-ubuntu and plymouth-theme-ubuntustudio: plymouth-theme-spinner. This parent theme relies on the ACPI to communicate the screen dimensions as opposed to assuming screen dimensions from a random sampling of one display, which is how the old method worked AIUI. This is error-prone when all displays are active as opposed to simply display 0 in the case of legacy themes.
TL;DR: a small change to the existing theme would never work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1969984 Title: [SRU] Kubuntu Plymouth Theme Shows Badly on Multi-Screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kubuntu-settings/+bug/1969984/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
