Help with autostart

[homac]

Have a question about autostarting a screen change. The command below works perfectly...

xrandr --output HDMI-1 --scale-from 1600x960 --display :0

I have been told to put the xrandr command in the file ~/.xsessionrc, then combine that with autostart. Being a total novice, how would I program that?

Thank-you...

The question seems unrelated to Python. We are a Python forum. It is a Linux desktop question. What exactly is your OS and desktop environment?
