How to disable ACPI? (on FreeBSD14 CURRENT)

I need to disable acpi and the indicated method for that is to add ^hint.acpi.0.disabled="1"^ in /boot/loader.conf .

However that crashes my system !!!!!! 

Not only that, to make it work again I have to edit loader.conf on a system which does ^not start^.  

 �

After a lot of searching Internet came to the help with, I could start the system again:

1. Select 3. Escape to loader prompt at the splash screen

2. Type set hint.acpi.0.disabled="0" on the loader prompt

3. Then type boot on the loader prompt

edit the loader.conf

Very very glad with that fix however

 �

However the problem is still there, no idea how to prevent the system from going to sleep (after about 10 minutes).

No idea how to change those 10 minutes to a much longer time as well .... 

 �

Note that I have gnome as gui and use the system more or less as server and manage the machine partly local via the GUI and partly remote via SSH.

 �

Related to GNOME I did try ^gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout 0^, however that did not solve the problem as well.

 �

In the end there seems to two problems

a) A BSD-issue ACPI-turn off in the bootloader is crashing the system ! ! and 

b) a GNOME issue (switching the system off during user inactivity, which is bullshit for a server / for ssh-login / with multiple users).

What IMHO apart from the screen lock, this is not a GNOME task but an OS  function to be configured by the system administrator.

 �

A third problem, not to be addressed here, is that recovery from sleep mode does not work on my system as well (even not S1).

 �

Most important for the moment is that the system keeps running / is not going down after x-time !
