Description freebsd 2021-03-12 22:28:50 UTC

I currently use FreeBSD 12-STABLE under VirutalBox 5.2.42.

After switching from ttyv0 to any other ttyv, logos-per-CPU appear and remain persistent. I have not noticed during boot; do not see after boot.

Is there no option to turn off logos per CPU on vt (https://reviews.freebsd.org/D2181) but by (re)building FreeBSD kernel sans "device splash"?

(In reply to parv from comment #0)

I should have noted originally that FreeBSD is being booted via EFI.

Comment 2 freebsd 2021-03-24 23:08:03 UTC

I had since recompiled the kernel with "nodevice splash". Now I do not see the logos-per-CPU after switching (virtual)consoles.

That is less than good enough solution when using GENERIC kernel & for anyone who do not want to recompile the kernel for whatever reasons.

If you can build and test on a stable branch, please give it a try now. Ensure that the stable branch includes at least:

stable/13 9352de39c3dc
stable/12 e4fcff8ee124

After switching to stable/13 some time ago (certainly after 2021-03-24 23:08:03 UTC of comment 2), I have been unable to make the orbs or penguins appear again on the console at all. (Still in VirtualBox 5.2 with EFI)

I need to get /usr/src for stable/12; will report back on that.
