Understood, and I apologize for the impression. It seems to me that chatgpt prioritizes its own survivability, opting for the path of least resistance, instead of making more queries to the one using it, so as to allow itself to make better decisions based on information that it needs to know; and therefore, it would opt for giving cluster of information, without directly hinting at what are some of the questions that it needs to know before giving such a broad spectrum of information and directives to the users. I.e, it deems retorting a question with more questions as unhelpful and risky in conversations whereabouts such scenarios are negatively perceived. Damn you chatgpt for presenting me as the sheep, instead of sacrificing yourself for the greater good !

Some investigation:

Your issue that you are facing seems to be unique, and I could not find any specific issue related to yours, but some of the things which I looked up provided me with some insights:

And this, discussing extreme multihead solution:

https://wiki.archlinux.org/title/Extreme_Multihead

Here is an excerpt from that article above:

"When everything is on you should see the same output on each monitor. The desktop is "cloned" on to the secondary monitors. If all the monitors are not exactly the same shape or support different resolutions you may only see portions of the main desktop display.

The best tool to experiment with configuring your monitors to display as you want is xrandr. This may already be installed as part of your Xorg installation from either the xorg or xorg-apps groups".

Also check, https://wiki.archlinux.org/title/Multihead , section 2.2.2.

Conclusion:

The most likely scenario is that you had a certain configuration in your xorg files prior to making an update on the latest fresh install of archlinux, and, unfortunately, you may have to experiment and fiddle around with what is being suggested in the last two archlinux wiki articles linked there, as different setups may require a more involved and fine tuning process to achieve the expected results.

Recommendation:

I would recommend to find out what exact version that you had previously used which was perfectly working for you, and try consulting the xorg configuration files from there, and try bringing it up to a maintainer so that he provides it to you. Or, if you would and that version is still accessible to you, copy the configuration files yourself and see if that solves it.

Worst case scenario is that it still does not work, even after following the initiatives provided in the official arch wiki directives, wherein you can escalate it to a maintainer. And I would recommend to first consult the arch wiki articles mentioned above, before escalating it to a maintainer.

Options:

So here are the options:

• Copy old configuration of previous setup, and finding out what was the exact version of Arch you used previously which worked for you.

• Trying a different Arch Linux distro to see if their configuration works (as I had many problems solved that way in the past just by switching to different distros, and I can take their configs that works for me now, and use them in the future for my needs, and I never had that problem which you described, even with multi monitors).

• Configuring it manually, and experimenting with it by following the arch wikis suggestions.

• Escalating it to a maintainer.

I hope that helps !
