Just my 2 cents, as a workaround, You could try to run this script on the notebook: ``` #!/bin/bash # set the display bus # example BUS='1' while true; do...

Have You tried to FIRST turn dpms off and THEN on, as the script? I don't know about sway, but You could try to set the output as e.g. DP-1,...

Ok done :+1: [ddcutil_1.4.0-dev_detect.txt](https://github.com/rockowitz/ddcutil/files/9486599/ddcutil_1.4.0-dev_detect.txt)

I don't know if it can help you, but i've build the following branches also: 1.0.0-release 1.1.0-release 1.2.0-release 1.2.1-release 1.2.2-release 1.2.3-dev all work till 1.2.2-release, starting from 1.2.3-dev ddcutil has...

Sadly the issue isn't solved, hope this will help at least to identify the problem: [ddcutil_1.4.0-dev_detect(2).txt](https://github.com/rockowitz/ddcutil/files/9487430/ddcutil_1.4.0-dev_detect.2.txt) ...if not, yeah it can be a significant bug, but there is no rush....

For the sake of completeness, i want to give you the output of both version 1.4.0-dev and 1.2.2 (as well as i2c kernel trace). I'm not an expert, but i...

Sure, enjoy your well deserved vacation, have a good time and thank you for all your work. Regards.

Hi and welcome back! With 1.3.3-dev displays are detected, but will give `DDC communication failed`. The relevant bus is i2c-1. Disregard i2c-4, it's a TV. edit: SORRY I'VE MESSED WITH...
