Public bug reported:
After upgrading to 24.04 LTS (Noble Numbat) from lubuntu 23.10 the system no
longer boots
except in safe mode. A fresh install of Noble Numbat was done, but this did not
resolve the problem.
In the grub file /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT='quiet splash' was changed to
GRUB_CMDLINE_LINUX_DEFAULT='quiet splash nomodeset '
and now the system boots.
