[odin-beta] Boot "error: Unexpectedly disconnected from boot status daemon"

GlasierXplor commented 3 years ago

Description of Problem:

There seems to be 2 errors on the boot splash screen.

The error: Unexpectedly disconnected from boot status daemon appears on both on the live CD, and the finished installation; The Failed to start Show Plymouth Boot Screen only appears in a completed installation.

plymouth cannot be found in journalctl -xe nor dmesg /var/log/boot.log does not exist, and thus I cannot see what happened on boot.

Screenshot of boot screen Screenshot from 2021-05-09 22-02-13

Expected behaviour:

The elementaryOS boot splash screen should be displayed on screen, then "boot normally" /var/log/boot.log should also exist (correct me if I am wrong)

What I tried

Some searching around suggests that it is a kernel incompatibility (for some reason). As such I downgraded the kernel from 5.8.0-50-generic to 5.8.0-49-generic. The errors stopped appearing, but the splash screen is still not showing (might be a separate issue altogether).

Platform:

elementaryOS 6.0 Public Beta elementary-os-6.0-daily.20210430.iso
linux-5.8.0-50-generic
VMware Workstation 15 (not sure if this might make a difference)

Does this also occur on Ubuntu?

GlasierXplor commented 3 years ago

My Ubuntu laptop is also on the same kernel (5.8.0-50). I do not see this issue on my laptop.

It happened to me after a bit much trying of plymouth using sudo plymouthd; sudo plymouth --show-splash ; for ((I=0; I<10; I++)); do sudo plymouth --update=test$I --debug ; sleep 1; done; sudo plymouth quit.

I changed a configuration file of the default plymouth and now it's broken. Reverted changes and still happening, reboot does nothing.

Plymouth start service is suprisingly running

arch-user-france1 commented 2 years ago

There is no pid-file for whatever reason

Restarting plymouth broke it: error: unexpectedly disconnected from boot status daemon

A person (scamming person) had this on ubuntu

This is the problem. Plymouth got quitted (forcefully?) but did not clean up. Does anyone have an idea how to fix that?

Oh: It looks like that's not the problem. I killed plymothd and now it's starting but following happens:

This might be it Could not load module "/usr/lib/plymouth/renderers/x11.so": /usr/lib/plymouth/renderers/x11.so:

It somehow works again, no clue why. The theme got reset (because I did pacman -R plymouth)?

arch-user-france1 commented 2 years ago

It seems to be a theme related issue. Doesn't work with my theme anymore.
