[Bug 2083299] Re: Ubuntu 24.04: Occasionally screen stays black while booting

[John Doe]

Hi Daniel,

it seems it fixed the behavior. I did now several reboots and it works.
Thanks a lot!

Q: 
Does this have any unwanted side effects?
Can I combine this again with quiet splash without any issue?


Note: This did not happen on 22.04. Machine itself is the same and has not changed.

Title:
  Ubuntu 24.04: Occasionally screen stays black while booting

Status in linux package in Ubuntu:
  Incomplete
Status in plymouth package in Ubuntu:
  Incomplete

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.
