opnSense 23.1 and screensaver or blank screen

[none]

Hi,

I am using an old notebook and the screen is on all the time. I am looking on how I can make it turn off after some time. I looked for it on google and could not find any hints on how to do it on opnSense.

Is there how to make it turn off after some time?

I tried changing the console type, no go here

thanks,

would closing the lid solve this?

Unfortunately, I don't have any advice to offer but I'd definitely be interested in whatever you find.

I'd also be curious if there was a way to make OPNSense always output video even if there isn't a display detected.  That way I don't have to reboot it if I need to connect a monitor.

would closing the lid solve this?

The problem with closing the lid is that some machines are designed so that keeping the lid open helps with cooling.  When you close it that can cause problems.

Hi, unfortunately not. The light is still on.

Closing the lid really would not be my first choice, due to heat. I live in a really warm place. But would easy the pain here, but no go

About the always present console, I got few issues using VGA monitors, machines that have HDMI I got some issues like yours.

The always on was more just my musing.  My OPNSense sits on a KVM and if it boots without being selected, then I end up not getting any video output until I reboot with it selected.  I could configure it to always be the selected machine but then I run into the same issue as you where it's always displaying and my monitor never goes to sleep.

Just for the record, I tried using external monitors through VGA or HDMI. Still no luck

Does opnsense is not built with the FreeBSD console options for that? The kernel modules loaded show no green or screensaver modules.

I wouldn't have expected it to.  I was just explaining my situation.  I use a desktop, not a laptop for my OPNSense.

I don't think you're going to have much luck with this as it's an uncommon situation.  I guess you could crack open the laptop and unplug the screen so that you use an external monitor only but that seems like a lot of work for not much reward.

Any reason not to switch to one of those small four port boxes or even an old desktop?

Maybe you could look at your acpi options.

Code: [Select]

$ sudo sysctl -a | grep hw.acpi.. Consult the freebsd manual i.e. https://man.freebsd.org/cgi/man.cgi?query=acpi_video&apropos=0&sektion=4&manpath=FreeBSD+13.1-RELEASE&arch=default&format=html
So you could try experimenting with hw.acpi.lid_switch_state for instance. Please note, I suggest you do this in a separate installation for testing. The wrong settings and you could blank out your console and need to re-install. At your risk.

I think the issue here is that there is no desktop environment with screensavers, compositors, etc. which would have those modules like screensavers. OPN by default only set to output to a text console, where these facilities don't exist in freebsd now using vt as the console.
It might be possible to go back to sc https://forums.freebsd.org/threads/how-do-you-set-a-screensaver-in-console-mode.54934/ but again BIG notice: test separately, you are likely to break something. This is a customisation of OPN you would be doing and probably remove prior to updates.
I am not suggesting you do this, only pointing to what might be the reason for the experienced behaviour.
