I am using manjaro linux with plasma desktop on a raspberry pi 5.
I have removed “squiet splash plymouth.ignore-serial-consoles” from /boot/cmdline.txt
I have also removed “plymouth” from the HOOKS in /boot/config.txt
Plymouth was then de-installed.
The system has been updated and initramfs_2712 and kernel_2712 created in /boot. (I believe the RPi5 kernels do not actually need initramfs to boot - all the needed modules are built into the kernel. )
On rebooting the device, i briefly saw the boot loader messages, followed briefly by a blank display, followed by the sddm login manager. The plasma desktop starts normally and everything is all OK,
Can anyone advise what I need to do to show the systemd messages on boot?
Unclear what you are asking. You adjust your monitor resolution if you want another resolution rather than what it defaults to or on some occasions like me here with my VIZIO tv it does not read my tv’s EDID info correctly. With out going into the adjustments I have made here this does not have anything to do with your boot messages not being displayed:
What plymouth hooks in config.txt. If you are referring to disable_splash=1 That is RPi’s Rainbow Splash which is irritating to me.
Sounds like it is not. I believe this is your issue.
sudo pacman -R plymouth plymouth-theme-manjaro
Then edit /etc/mkinitcpio.conf
Change: MODULES=(vc4) ==> MODULES=()
Remove from the HOOKS= line: kms
Then adust /bootcmdline.txt as I posted above then reboot.
