How to schedule on off in magic mirror

sdetweil

@1a2a3a what os version are you running
do

lsb_release -a
uname -a

on what device? pi3, 4?

many os changes have caused different screen off functions to no longer work

like
tvservice is no more
vcgencmd works on some
xrandr works with xwindows, not with wayland
cec-client works in my pi4, not my pi3
there are new Wayland commands

I don’t know what different modules support, many have not been updated in quite some time.

there is no required commitment to maintain 3rd party modules. they are ‘as is’ in many cases. but open source for anyone to enhance

@sdetweil hello

No LSB modules are available.

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

@1a2a3a sorry I don’t know xrandr.
