Solved X11: server does not have extension for -dpms option

Hello, I'm running 14.0-RELEASE-p2 on a Dell Optiplex Micro, using XFCE. The processor is Intel i5-13600, and the graphics Intel UHD 770 (AlderLake). I know the graphics are not supported, but I don't believe that is the issue here.

The X server initializes as shown by these excerpts from /var/log/Xorg.0.log:

Code: 
X.Org X Server 1.21.1.9

So the dpms extension seems to be found and initialized. But then
Code: 
[ko@hn ~]$ xset -dpms
server does not have extension for -dpms option
[ko@hn ~]$

This prevents the xfce4 power manager from running and controlling the display.
I do not understand what is going on.

I was hesitant to give my 'usually wrong' 2 cents.
But my first wonder is; SCFB and does it even support dpms?
I thought drm might be needed for dpms

Good question. The man page does not make this clear.
Anyhow, the background of all of this is that my Intel UHD 770 graphics are not supported by drm-515-kmod: with it and the corresponding gpu-firmware-intel-kmod-alderlake, the machine freezes on booting. See https://github.com/freebsd/drm-kmod/issues/252, which includes my posts.
So using scfb allows the system to boot and Xfce shows that the llvmpipe GPU is used. But then there is the DPMS problem which doesn't allow the Xfcescreensaver or power manager to work properly.
