Xlib: extension "DPMS" missing on display ":0.0", 14.0-RELEASE, xfce4

Hi, I'm running 14.0-RELEASE on a Dell Optiplex Micro, with xfce4-4.18.

My .xsession-errors is filled with the message
Xlib: extension "DPMS" missing on display ":0.0".
which seems to be generated every few seconds.

The GPU is Intel UHD 770 graphics, which is not currently supported, so XFCE uses the "llvmpipe" GPU.
I am not running powerd, just XFCE's upower.

Anyone have any ideas as to what may be wrong? Thanks.
 
Try and disable it from the command prompt.
xset -dpms
If that works to quiet output make a /usr/local/etc/X11/xorg.conf.d/10-monitor.conf
Code: 
Section "Monitor"
    Option "DPMS" "false"
EndSection
 
I've tried that before, forgot to mention it:
[ko@hn ~]$ xset -dpms server does not have extension for -dpms option [ko@hn ~]$
