Have a laptop running RHEL 8.4 without the gui. I would like to power off the display. I use to run vbetool dpms off on ubuntu but that doesn't work,

user@server# ls /sys/class/drm
card0  card0-DP-1  card0-HDMI-A-1  card0-LVDS-1  card0-VGA-1  renderD128  version

[Update] I'm not using Wayland or X11, session type is shown as tty.

user@server$ loginctl show-session "$XDG_SESSION_ID" -p Type
Type=tty

[Update] These commands complete successfully but have no affect

user@server$ setterm --blank force 
user@server$ setterm --powerdown 1

This didn't work for me I couldn't get it installed correctly. – m0ng00se Jun 26 '21 at 17:41
After running this command it shows im not using wayland or x11 instead it's tty `loginctl show-session "$XDG_SESSION_ID" -p Type` `Type=tty` – m0ng00se Jun 26 '21 at 17:58
