How do I create a startup command permanent on every cycle restart ? As previously having brightness reset when set at power saving mode to turn off the monitor.

I found out xset dpms 600 900 1800 works on turning off the monitor display but I wanted it to run at startup which i do no need to type manually on the terminal.

I tried adding xset dpms 600 900 1800 to the bottom of home/.profile but it didn't work.

Further testing and by adding an extra line to run terminal by adding

xset dpms 600 900 1800
gnome-terminal

at the terminal startup checking the xset -q xset dpms was not set Standby: 0 Suspend: 0 Off: 0 while it should be Standby: 600 Suspend: 900 Off: 1800

The weird scenario is when manually launch a terminal without typing anything , the command of xset dpms 600 900 1800 active.

What would it be the reason ? .profile with command 'xset dpms 600 900 1800' Not trigger on startup but when I launch terminal manually it trigger the command.

If anyone could explain the reason ? or a better way to run the command on startup rather running on .profile ?

When I set power saving to blank screen on an external monitor to turn off the monitor for power saving, it gets reset to default 100% brightness once power saving is active.

I'm not familiar with Bash, but I wondered if I could write a Bash script to automatically turn off the monitor without going to active blank screen?

I have installed xprintidle to detect the idle time.

Here is how I wanted it to run:

If idle time is over 600 seconds (10 minutes) then run this power off monitor command xset dpms force off

I want it to load on startup and keep on running like a service which will turn off the monitor if idle for 10 minutes.

How can I achieve this?
