This reminds me of bug 1869655, which may be worse on Nvidia systems if
there is no driver loading early enough.
It might also be because the boot GPU has been hidden. I can tell this
machine has two GPUs; Intel and Nvidia. But the Intel GPU is no longer
listed as a PCI device. Though that might not matter if the simple
framebuffer used during early boot is still available via BIOS
interfaces.
The Plymouth log suggests a combination of these issues:
got add event for device /dev/fb0
ignoring since we only handle subsystem graphics devices after timeout
and
creating objects for frame buffer devices
found device
/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/efi-framebuffer.0/graphics/fb0
device is initialized
found node /dev/fb0
device subsystem is graphics
found frame buffer device /dev/fb0
trying to find associated drm node for fb device (path:
pci-0000:01:00.0-platform-efi-framebuffer.0)
no card entry!
Please try adding this kernel parameter:
plymouth.use-simpledrm
I'm guessing that will fix it and this will be a duplicate of bug
1869655.
