Same symptoms occur with NetBSD with DRMKMS, which is their name for vt or newcons.

I can only guess it would occur with Linux too and would not fight it.

X will not start from sc in FreeBSD or NetBSD.

I have wondered if console screensaver could be made to work with vt or DRMKMS, but then there is the danger of not being able to come back from screenblanking.

I no longer use sc in FreeBSD.  In NetBSD, I like booting into 1920x1080 video mode for console and getting 67 (?) rows and 240 columns.

1920x1080 is my monitor's native mode and recommended by the manufacturer (LG).
