Dual monitors on startup.

Today i configure xrandr to finally use my two monitors,everything works fine with i3 and stuff.The only problem that i have is that i have to run the: "sudo xrandr --output DP-1-0 --auto --output DP-1 --auto --right-of DP-1-0" command every time i launch to have dual monitors enabled.

Here's the xandr output:

Re: Dual monitors on startup.

Welcome to the forum.
Please use code tags for terminal output

[code]
your code here
[/code]

You should not need sudo for this command. If you always boot with both screens turned on, then you could execute xrandr in your i3 config.
https://wiki.archlinux.org/title/I3#Autostart

Otherwise configure an automatic tool to configure your screen and add that to your autostart.
https://archlinux.org/packages/community/any/autorandr/ or

Re: Dual monitors on startup.

You probably don't want to use xrandr at all and under no circumstances sudo it.
Get the sudo-will-fix-it mentality out of your head afap.

https://wiki.archlinux.org/title/Multih … _xorg.conf

Section "Monitor"
    Identifier "DP-1"
    Option	"Enable"	"True" # this is the default anyway
    Option	"Primary"	"True"
    Option	"RightOf"	"DP-1-0"
EndSection

Section "Monitor"
    Identifier "DP-1-0"
    Option	"Enable"	"True"
    Option	"Primary"	"False"
    Option	"LeftOf"	"DP-1" # you need only one of the positional options, preferably for the optional output
EndSection
