How to save xrandr options?

Question

In order to get full RGB output (0-255) on my Intel UHD630 integrated graphics I have to run this command at every reboot:

sudo xrandr --output HDMI-1 --set "Broadcast RGB" "Full"

Is there a way to save this so that it runs automatically when X starts?

I'm running Ubuntu 19.10.

Yes, there is a way. You'll have to define these settings in /etc/X11/xorg.conf , specific syntax is required — Sergiy Kolodyazhnyy, Dec 19 '19 at 04:43

You can run a command directly at every reboot using cron jobs First, create a small script and save it.

#!/bin/sh
sudo xrandr --output HDMI-1 --set "Broadcast RGB" "Full"

Open terminal and run

crontab -e

Then type

@reboot /path/to/script/<scriptname>.sh

Replace the path and the scriptname

Finally, enable cron service

systemctl enable crond.service

I created the script and put it in "Startup applications" instead of crontab, seems to work fine on reboot – Chef Tony Dec 19 '19 at 10:00
