How to disable sleep on my desktop with Freebsd 13?

I'm running a Gigabyte X99 Ultra Gaming motherboard with an Intel
5960x. I just upgraded from 12.2 to 13.0 and now my system goes to
sleep after a few minutes when I don't touch the keyboard or mouse.

I'm in gnome3 and checked the power settings but it only offers
configuration for my display which I have set to never sleep.

I'm trying to figure out how to disable sleep altogether, but google-
fu has failed me. Here are the values of my \`sysctl hw.acpi\`:

$ sysctl hw.acpi

hw.acpi.cpu.cx\_lowest: C1

hw.acpi.reset\_video: 0

hw.acpi.handle\_reboot: 1

hw.acpi.disable\_on\_reboot: 0

hw.acpi.verbose: 0

hw.acpi.s4bios: 0

hw.acpi.sleep\_delay: 1

hw.acpi.suspend\_state: S3

hw.acpi.standby\_state: NONE

hw.acpi.lid\_switch\_state: NONE

hw.acpi.sleep\_button\_state: S3

hw.acpi.power\_button\_state: S5

hw.acpi.supported\_sleep\_state: S3 S4 S5

​

How do I disable sleep?

I could be mistaken, but

x set s off && xset -dpms

should do it

What exactly do you mean by 'sleep' ?

FreeBSD itself never enters sleep states (S1, S3) without a user
action.

Now says DPMS disabled which I guess is a start.

It's suspending to disk and turning itself off which I believe
corresponds to S5. I have to hit the power button for it to resume. It
all comes back up again (usually) but I don't want it to go into S3 or
S5 \_at all\_.

I don't mind the screen turning off after some set period. But I do
not want the CPU and disks to go to sleep.

For Gnome you should do:

gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-
ac-timeout 0

This command worked. Thank you for the assist.

Seems odd to me that the window manager / desktop manager would be in
charge of this. I figured I could prevent it at the kernel level by
disabling the acpi power mechanism, but I guess not. :shrug:

S5 is a power off (shutdown).

S4, FreeBSD does not support.

So, it is likely S3.

It really must be something in the DE (gnome3) or other third-party
software.

Vanilla FreeBSD never auto-suspends.

Thanks to everyone who responded. The correct answer was to adjust the
desktop manager to disable DPMS. In my case, it was gnome (see the
command in this thread). I added that to my shell's .rc and all is
well.
