Well, thinking about loading many christmas trees into and out of suv's and station wagons over the years, I can tell you that it's going to be a lot better in one direction than the other.
I don't think anyone is going to come smash down your door because you installed Ubuntu. But I don't know what country you are in and two years ago I wouldn't have believed Iranian police would kill people over wearing a hijab. So I think you should do it, but I also think you should stay safe.
Worked with no drama, for me at least. Hooked it to my TV because that was most convenient. USB-C to HDMI adapter, I just had to tell it where they were in relation to each other and set scaling on the TV. Fonts look a little screwy on that dialogue box, but only in the screenshot - and when composing this post I realized even there they look OK if I don't view that part of the screenshot on the 4K display.
Edit: No, untrue. I think I had the wrong glasses on. The fonts on the 1080p display are fine in reality, but the screenshot is distorting everything on that panel a bit. Again, screenshot only though. All good otherwise. I can't see any other problem after using it a bit like this though.
I'm fairly sure I have run this system dual-monitor though I don't do it routinely. I'll check sometime this weekend and let you know, if you are interested for comparison's sake.
The problem, as I see it, is that the author of the original Gist does not really want wayland replacements for what he has, but rather what he has to also work on wayland.
It's like the Windows users expecting to use all the same software on Linux when they move over problem, but in microcosm.
Wayland does not work properly on Intel hardware: Again, I’m using AMD, so I can’t confirm or deny this, but considering the Intel drivers are open source, and I’ve heard about many, many improvements made on the Intel side of things, I think it would be reasonable to assume it has been fixed.
Posting this from Plasma Wayland on Intel right now. If something is broken, it's something not apparent to me.
The year of the Linux desktop is right now, if you want it to be. For me it was 2007 - and watching the evolution of Windows since then has been a continuous validation of my choice.
If you want to use Linux, use it! It's ready, and IMO has been for some time.
(And just to be clear - choosing otherwise is OK too! I don't intend my enthusiasm as zealotry. Folks making an educated decision to stay is totally valid.)
