I have the latest Raspberry Pi OS (Debian Bullseye) on a Raspberry Pi 4. I want to achieve a setting whereby after a period of time the session will lock and no signal will get sent through HDMI so the monitor can switch to a sleep mode.

The default settings allow for the screen to blank (no signal sent to HDMI monitor so that the monitor can go into a sleep mode) after a period of time. However, it does not lock the screen. Xscreensaver allows for a lock screen but still sends a signal with a black image to the monitor such that the monitor will not sleep.

How do I achieve both a locked screen and no HDMI signal after [10] minutes of inactivity?

Seems like you want a configuration for DPMS (display power management signalling). Also assuming you stick to X11 display, you can try the following commandxset q to get your current settings. To replace black screen with X11 logo on a blue background when screen blanking sudo xset noblank . To set the display to standby after 2 minutes, suspend after 5 minutes, turn off after 10 minutes of inactivity sudo xset s 120 300 600 .

If none of these work you may try this [tool]2 and edit the Xscreensaver database file and edit the lock,locktimeout and dpmsOff parameters
