You can specify an action for Screens to trigger just before disconnecting from a remote computer.
These actions can be performed:
- Trigger a Hot Corner.
- Log out the current user on the remote computer.
- Send a Ctrl-Alt-Del command.
For example, in your Mac’s System Preferences, you can configure the top-left Hot Corner to “Put Display to Sleep”. Specifying a trigger for this Hot Corner in Screens will turn off the display of the remote computer when you disconnect your Screens session.
