Kubuntu 24.04 Second boot always black screen

[Scarlett Gately Moore]

Install works fine, first boot works fine. Second boot goes to black screen. Doesn't matter if updates are applied or not. Booting by way of recovery mode DOES work. This system has an Intel video chipset but it seems to affect Nvidia and AMDGpu as well as reported on the interwebs.

replacing 'quiet splash' with '' from GRUB_CMDLINE_LINUX_DEFAULT /etc/default/grub also allows a clean boot.

Next time the problem happens please:

1. Reboot.

2. Run:

   journalctl -b-1 > prevboot.txt

3. Attach the resulting text file here.

replacing 'quiet splash' with just'quiet' from GRUB_CMDLINE_LINUX_DEFAULT /etc/default/grub also allows a clean boot.
