Question xset dmps force off doesn't work in cron


sleep 1
xset dpms force off

I add two lines above to the script, and manually run it, it works as I expected.
But when the script runs by cron, the "xset dpms force off" doesn't work.
anyone had an idea?

afaik, cron does not use any environment variables.
so,
a) you need to use the full path to the executable
b) have to tell xset what $DISPLAY is set to
c) is cron running as root? might have to sudo to normal user.

edit:
in retrospect, this seems like an x-y-problem to me.
what are you really trying to accomplish here?
