Don't do that. One of the problems of the Debian boot system is that it
starts too many services in runlevel S. When you switch too runlevel 1,
they get killed and will not be restarted in runlevel 2. This includes
udev, among others¹.

The X server relies on udev for detecting input devices, and if udev is
not running this will not work.

Sadly, the most sensible thing after entering runlevel 1 is to reboot.
Otherwise you have to restart udev, dhclient, wpasupplicant and what not
by hand which is cumbersome and error-prone.
