[Bug 2103533] Re: plymouth library crashes and doesn't show splash screen

[Daniel van Vugt]

I thought 'SIGRTMIN+N' was used for IPC so it might not relate to
crashes. Let's ignore that and...

Thank you for taking the time to report this bug and helping to make
Ubuntu better. It sounds like some part of the system has crashed. To
help us find the cause of the crash please follow these steps:

1. Run these commands:
    journalctl -b0 > journal.txt
    journalctl -b-1 > prevjournal.txt
and attach the resulting text files here.

2. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

3. If step 2 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.

Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.

Title:
  plymouth library crashes and doesn't show splash screen

Status in plymouth package in Ubuntu:
  Incomplete

Bug description:
  I got errors instead of the plymouth splash screen related to libply. Unfortunately I couldn't find the logs for the error on journalctl, but I could find something like this:
  mar 18 12:11:30 glados systemd[1]: Received SIGRTMIN+20 from PID 391 (plymouthd).
  For some reason plymouth is crashing.
  Please, let me know where I can find the logs for plymouthd since it doesn't seem to have a service unit for it.
