Never had any problems with my 4K screen in Manjaro KDE, and only needed to change Xft.dpi in .Xresources in Manjaro i3

I’m not saying it cannot work but I am saying an IT department cannot just install Ubuntu on a laptop, hand it to someone who doesn’t know how to hack at Linux, and have the display aspects “just work” with any monitor.

I have no beef with Linux, but we have to be honest about what it needs to be capable of to compete with MacOS for the general user unable or unwilling to hack at it a bit.

If the solution in any way involves "enter this command", you have lost the vast, vast majority of users. Those users will never have any idea that "Catalina broke SSH".

I think you are wrong. I have seen it happen more than once, even in my current company. Especially when companies use mostly online tools, like our case, it's a no brainer.

Do you mean I am wrong that standard users won't notice ssh broken?

You're right, my statement may have been too strong.

We do know that Catalina isn't broken for everyone though as alluded to by others in this thread. No one in my company or anyone I personally know with a MacBook has been affected. There must be another interaction happening.

Sorry, no, I mean that you can really give Ubuntu units to people and expect it to work without any issues. If this works in schools it works also for power users :)

I've never had a problem with my 4k in fedora, but I only have a single monitor

Linux had good support for multiple monitors when I started using it in 2003. Obviously something is crashing but it's not apt to be plugging in a monitor.
