Problem

I’m using two monitors, and one of them is pivoted. The default display setting manager of Manjaro has an option for rotating view, but it was not applied when using i3wm.

Solution

xrands was used. In a terminal, you can get the information of currently connected monitors with xrands without any options. (The following example shows the monitor status after applying settings.)

$ xrands

You can change the display settings with options. I wanted to rotate the second monitor left and modify its vertical position to be matched with the primary monitor.

xrandr --output DVI-D-0 --rotate left --auto --pos 3840x700

The setting will be applied right after you enter the command.

This setting is not maintained after rebooting. The command should be written in the file: ~/.xprofile to be executed on startup.
