Shutdown messages not displayed

I disabled graphical boot and therefore see system messages on startup. On shutdown, I instead see a frozen part of the boot messages before entering the graphical target. As sometimes the shutdown hangs, it would be useful to see what is stalling the shutdown process.

Re: Shutdown messages not displayed

journalctl -r -b -1
-r stands for reverse order
-b -1 says which boot (here -1)
probably an sddm (in case you use it) issue (installing sddm-git should help)

Re: Shutdown messages not displayed

sddm-git did change from frozen startup screen to a black screen with no information, so the problem seems related to it.

journalctl -r -b -1:

Re: Shutdown messages not displayed

I don't see any shutdown hangs. sddm-git has a fix for that.
if you want to see the issue, wait/try rebooting for the issue and then post the output.

sddm-git did change from frozen startup screen to a black screen with no information, so the problem seems related to it.

was your sddm(not git)/boot broken or what is the problem you are trying to resolve?

Re: Shutdown messages not displayed

I am not complaining about the hangs, as I assume these are just long timeouts. On openSUSE, I was able to see the systemd log also on shutdown, not just on boot. I am trying to restore this behavior with Arch Linux.

Re: Shutdown messages not displayed

maybe this? https://wiki.archlinux.org/title/SDDM#K … and_reboot
EDIT: it works on my machine, so it isn't distro-specific. I guess you do not have a splash/quiet/loglevel parameters?

Re: Shutdown messages not displayed

The journal shows a reboot/shutdown taking place in <= 2s - is that the time of the objected stall?

Re: Shutdown messages not displayed

After https://wiki.archlinux.org/title/SDDM#K … and_reboot the reboot is super quick that I no longer really need to look at any command line output on shutdown.

Also tried https://wiki.archlinux.org/title/SDDM#B … phics_card but that only added some screen flicker to the boot and didn't help with my initial problem.

Another weird thing that I noticed is that F1 to F6 don't generate a new text login prompt even after https://wiki.archlinux.org/title/SDDM#S … ad_of_tty7

I have quiet splash removed and nowatchdog added because I thought that was the reason for the stall.
