Going to change this back to linux as the plymouth failing to display indicates an issues with KMS (plymouth uses KMS to display graphics on earlyboot which is what is happening here). The bootlogo from plymouth always shows (even for a very brief time) when SDDM starts and when it boots to a black screen the bootlog NEVER shows from plymouth. Using your reasoning of the race condition I should see the bootlogo at least sometimes in the boot to black screen but this has never happened (I have booted dozens of times to black screen and have always never seen the bootlogo).

I do not think this has anything to do with sddm. If KMS is not working then of course everything else that relies on it later in the bootstack will also fail.

The Ubuntu default drivers are in use.
