Devices that are marked with "uaccess" get an ACL installed that
always points to the user who owns the foreground session. This should
be applied whenever you log in or switch foreground session.

If this doesn't work at login time there must be something borked with
your display manager, or possibly systemd-logind.

Which systemd version is this? Which distro? Which display manager?
