Bug#1032412: desktop-base: plymouth theme does not show any messages, affects: luks, live

[Jonathan Carter]

Package: desktop-base
Version: 12.0.5
Severity: important

The latest plymouth theme for Debian 12 doesn't show any messages/prompts/fields.

The consequences of this is that when you boot up, you don't see the prompt to decrypt your disk, so it appears that the boot process has frozen (until you press escape and see the console luks prompt).

On live systems, when you reboot/shutdown, the user is prompted to remove the live media and press enter, but since this message is now not visibile, it appears that the system has frozen (until the user pressess enter).

Marking as important, since this is quite a big regression.

I have the same problem at dual screen with sizes 1280 x 1024 and 1280 x
800.

New debian-logo tries to write the message "resuming from hibernation"
below borh screens.

This is caused by wrong computation of max height.

In my case it computes 2 * 112 + 1024, which should be only 1024.

.Problem occurs at /usr/share/plymouth/themes/emerald/emerald.script.

Next patch solves the problem for me :diff --git

At plymouth the computation of Window.GetWidth() and Window.GetHeight()
has changed 2 years ago. It now contains the sizes of the
largest screen i.s.o. the smallest screen.
