Make resolution permanent

I can change my resolution using xrandr but where and what do I configure it to use the resolution at bootup?

I used xrandr --output HDMI2 --mode 1920x1080 to set the resolution.

Thank you. My settings are below:

Most desktop environments can restore the previously set display configuration when you log in. Otherwise your option is to put that into a startup script or into the Xorg configuration.

To make the screen resolution permanant I did the following :-

Query the screen details

xrandr --query

My output was

Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
HDMI1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 600mm x 340mm

   720x400       70.08  
HDMI2 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

Here there are three screen outputs HDMI1, HDMI2 and VIRTUAL1.

I want the connected screen which is HDMI1.

The resolution (mode) of HDMI1 is 1920x1080.

Modify the i3 configuration file:

~/.i3/config

exec xrandr --output HDMI1 --mode 1920x1080

Then I did a reboot (but you could probably just restart i3).
