systemd-logind tracks the active user / session (you can check with
loginctl). For that it monitors vt switches to determine the active user.
It then applies rw ACLs for all devices which have been tagged by udev
with the :uaccess: tag, to e.g. grant access to /dev/video0.

Apparently this fails on your system, most likely due to you having a
custom kernel.
What does
cat /boot/config-$(uname -r) | grep -E "(DEV)?TMPFS"
say?

That's from the default Debian kernel:
CONFIG_DEVTMPFS=y
# CONFIG_DEVTMPFS_MOUNT is not set
CONFIG_TMPFS=y
CONFIG_TMPFS_POSIX_ACL=y
CONFIG_TMPFS_XATTR=y

I assume, CONFIG_TMPFS_POSIX_ACL and CONFIG_TMPFS_XATTR are not set?
