It works for me on my bullseye install. I have no display manager, and use startx to start X sessions. My ~/.xsession just launches a window manager (ratpoison). Maybe this accounts for the difference we each see. There are some notes about DPMS here that may help you: https://wiki.archlinux.org/title/Display_Power_Management_Signaling#Modify_DPMS_and_screensaver_settings_with_a_command In particular, maybe one of these two: * XScreenSaver and xfce4-power-manager use their own DPMS settings and override xset configuration. See https://wiki.archlinux.org/title/XScreenSaver#DPMS_and_blanking_settings https://wiki.archlinux.org/title/Xfce#Display_blanking * If using the command manually in a shell you may need to prefix it with sleep 1; for it to work correctly, for example $ sleep 1; xset dpms force off But there are more notes on that archlinux DPMS page. -- Hackers are free people.
