@ -162,12 +162,6 @@ Then, similarly to the previous command, you need to enable the Ly service:
# systemctl disable getty@tty2.service
```
On platforms that use systemd-logind to dynamically start `autovt@.service` instances when the switch to a new tty occurs, any ly instances for ttys _except the default tty_ need to be enabled using a different mechanism: To autostart ly on switch to `tty2`, do not enable any `ly` unit directly, instead symlink `autovt@tty2.service` to `ly@tty2.service` within `/usr/lib/systemd/system/` (analogous for every other tty you want to enable ly on).
The target of the symlink, `ly@ttyN.service`, does not actually exist, but systemd nevertheless recognizes that the instanciation of `autovt@.service` with `%I` equal to `ttyN` now points to an instanciation of `ly@.service` with `%I` set to `ttyN`.
Compare to `man 5 logind.conf`, especially regarding the `NAutoVTs=` and `ReserveVT=` parameters.
On non-systemd systems, you can change the TTY Ly will run on by editing the corresponding service file for your platform.
