Are you certain it hasn't started on some TTY other than 8?  I always 
start out on TTY1, although I start up text only, no SDDM. However, I do 
have a very vague memory of something similar, and I believe it was that 
I needed to change one of the kernel FB related settings.  Sorry not be 
have more concrete suggestions.
