ill be damned. managed to get it to work using this after some searching

Edit the “config.txt” in the “/boot” directory.

Go to:

“# Enable DRM VC4 V3D driver
dtoverlay=vc4-kms-v3d
max_framebuffers=2”

And change “dtoverlay=vc4-kms-v3d” to “dtoverlay=vc4-fkms-v3d”.

There is a bug in the “vc4-kms-v3d” driver.

After changing in the “config.txt” “vcgencmd display_power 0” returns a “display_power=0”.

@sdetweil

i have also check that wayland is enabled.

when i ssh from terminal it says fail to connect to display.

but when i type wlr-randr on the pi itself, it has result. but i didnt trigger the off because i have no idea how to turn it back on?

Also, this is my code in cron but it doesnt work as well…
52 17 * * * /usr/bin/wlr-randr --output HDMI-A-2 --on
51 17 * * * /usr/bin/wlr-randr --output HDMI-A-2 --off
