Title:
Disk unlock prompt is never displayed. Screen stays black.
Status in plymouth package in Ubuntu:
New
Bug description:
Unfortunately the screen stays black before password prompt shows up.
This happens since I've migrated from 22.04 to 24.04.
Even a fresh install shows the same symptoms.
What helps is to detach the HDMI cable, attach it again and the TV
shows the password prompt for luks.
I did not try yet the removal of "splash" in the parameters. As this
was indicated by others who faced the same issue.
