Greetings everyone.
First, background: currently I have triple 4k monitor desktop setup that runs on a single 1050ti videocard.
Planning to upgrade to six 4k monitors and for that I bought additional vcard to supplement my 1050ti.
The card I bought is gt 730. And I know - it doesn’t sound like a vcard that can support 4k monitors, but it does. I tested it, and on windows it works like a charm.
Well it is obvious that it will support that because this vcard is made to hold 4 monitors and had 4 hdmi sockets.
More info on this particular card you can find on asus website. It’s GT730-4H-SL-2GD5 vcard.
Cannot link it because the forum doesn’t allow me to post links.
And another vcard as I said is Palit 1050ti.
But this setup is temporary. Until prices for videocards drop anyway.
So yeah, while it works on windows I have a hard time to make this work on linux.
I am on manjaro (5.13.13-1-MANJARO x86-67), with nvidia proprietary drivers (470.63.01), and on i3wm.

And ofc. I tried multiple variants, googled at least a dozen of different solutions, but so far I only succeeded in seeing “cannot start lightdm” message, so I humbly request your help.
I also stumbled upon the tutorial form oreilly, " Chapter 4. Advanced Xorg Configuration", and followed it’s instructions so far also to no avail.
Also seeing how it recommends CRT monitors for artists I wonder what year this tutorial is from.
And sorry that I cannot post links on this tutorial because I am unable to. But I think you can easily google it quick.
So far Xinerama option doesn’t work as well that I was unable to create additional X screen. There is no info on the internet how to create one manually or with the help of some utility.
TL;DR:
I need to establish 6 monitors double vcard setup.
I probably need to create additional X screen and use Xinerama option for that, but there is not much info on how to use them. And so far nothing from suggested doesn’t work. Or I’m not attentive enough.
Thank you for any of your help.
