description |
BIOS logo (the ACPI BGRT graphic) reappears mid-boot after the purple screen.
This seems to be happening reliably on multiple focal machines:
0. Turn on or reboot the machine.
1. See the BIOS logo.
2. See a blank purple screen (grub)
3. See the BIOS logo again (this bug)
4. See the purple screen with Ubuntu logo (plymouth)
5. See the login screen
I believe this is related to ACPI BGRT changes in the kernel. And I guess it wouldn't even need fixing if we just eliminated the blank purple grub screen (step 2)...
