I have openSUSE Tumbleweed 20240419, Plasma 6 installed on this machine. My question for you is when I review log with 'journalctl -b' I see two lines, relating to, I think - Unknown kernel command line parameters . The two lines are below. Thinkcentre-M57p kernel: Kernel command line: BOOT_IMAGE=/boot/vmlinuz-6.8.7-1-default root=/dev/mapper/system-root resume=/dev/system/swap nvidia_drm.modeset=1 splash=0 plymouth.enable=0 mitigations=auto nosimplefb=1 security=apparmor Apr 21 10:45:44 paul-Thinkcentre-M57p kernel: Unknown kernel command line parameters "BOOT_IMAGE=/boot/vmlinuz-6.8.7-1-default splash=0", will be passed to user space. - I have included the '/etc/default/grub' file below. The file has *different* entries, especially in the in it compared to the entries displayed in the log above. Thinkcentre-M57p:~> cat /etc/default/grub # If you change this file, run 'grub2-mkconfig -o /boot/grub2/grub.cfg' afterwards to update # /boot/grub2/grub.cfg. # Uncomment to set your own custom distributor.

I believe the "splash=0" can be safely removed and is related to Plymouth. How serious are these errors and can they be fixed and how? -regards
