--- Comment #5 from Guilherme Janczak <guilherme.janczak@yandex.com> ---
This bug caused burn-in on an old laptop I use via remote access. The FreeBSD
login prompt was burned onto it after weeks/months continuously on and with the
lid closed.

Setting kern.vty=sc in /boot/loader.conf caused the laptop to boot to a blank
screen. sc's man page appears to warn against this on UEFI systems, but this
laptop is BIOS.

A workaround is to start the xdm (X Display Manager) service on boot, closing
the lid will then turn off the screen.
