The Linux kernel disabled console blanking by default in 2017. https://git.kernel.org/pub/scm/linux/ke ... 0a7b0a99ed This is very unhelpful for users wanting to boot to console (such as when the Pi is accessed remotely over ssh, but still has a monitor connected). This means of the various inputs to your monitor, the Pi console output will keep your monitor on preventing power-down/power-save mode from working on the monitor.
This was always the downside consequence of the decision to disable console blanking in the kernel. Thankfully, you can create a simple system-unit file and drop it in /etc/systemd/system to restore the default 5 min blank, 6 min DPMS powerdown. The following named console-blanking.service works fine:
As a user service file it will be enabled by default on next boot. You can simply start the service sudo systemctl start console-blanking to enable for the current boot without the need to restart the Pi.
Let me know if you have comments or improvements.
