cron job hdmi on and off

[Sam 0]

ok i checked some more and did some tests

when I execute the following I get the error message that I also see in the log

/usr/bin/wlr-randr --output H DMI-A-1 --off
failed to connect to display

also running the sh files via putty gives the error
it seems that the command:
/usr/bin/wlr-randr --output H DMI-A-1 --off
the error message gives the question is this command incorrect or is there an underlying problem?

@Sam-0 Can you run the following from the command line and she your results:
wlr-randr
ls -als /run/user/1000/wayland*

Share your results. Either the wayland-1 is different as indicated by @evroom or HDMI-A-1 is actually a different version on your system.

Share the results from the above and we take it from there. Also, @evroom has indicated the there is supposed to be a space before /home on the crontab.

@Sam-0 this is the result

checked the cron see below

[evroom]

@Sam-0

So as stated before you most probably need to change wayland-1 to wayland-0 in your scripts.
Give it a try.
Furthermore the .lock file may cause a problem, but I guess this will show in your error log.
And temporarily change the times in your cronjob to speed things up a bit.
Waiting till ten and midnight is not really necessary :-)

@evroom *.lock should not cause an issue. I have same on my system and no issues with it. I agree with the wayland-1 change to wayland-0.

[Sam 0]

@evroom

should it be modified in this way?

output HDMI-A-1 --on
Into
output HDMI-A-0 --on

[evroom]

No, like this:

export WAYLAND_DISPLAY=wayland-0

In both scripts.

@evroom said in cron job hdmi on and off:

export WAYLAND_DISPLAY=wayland-0

this way?

[sdetweil]

@Sam-0 no… the exports have to be before the wlr_randr

[Sam 0]

@sdetweil
thank you i made the adjustment

[evroom]

@Sam-0

You only had to change the 1 into a 0.
Not to move the lines around, especially not the ones with export.

#!/bin/bash
export WAYLAND_DISPLAY=wayland-0
export XDG_RUNTIME_DIR=/run/user/1000
wir-randr --output HDMI-A-1 --on

But you are slowly getting there :-)
Wax on, wax off
Screen on, screen off.
