Hi,
Created a new thread as this one was already closed and can’t be replied to.
I had the same problem with OP, and applied the same configuration as suggested. But following a reboot, I lost display on my second monitor. Any help is greatly appreciated.

I’m not sure why but the issue is fixed after another reboot. Here’s the relevant for inxi/graphics portion of my working config.

So the issue fixed itself after 2 reboots instead of a single one?
