MacOS actually in my experience seems to handle this all perfectly. Normal-DPI screens you chose resolution and dragging windows between monitors works as you naturally expect (it pops between DPIs).

Concerning DPI and trackpad integration, Ubuntu should strive to be as Mac-like as possible, at least imo. Macs absolutely win in the trackpad arena; multitouch works like a dream, configurable gestures aplenty to achieve whatever you want (of course, it could always be more customizable).

DPI scaling between monitors work exactly as you'd expect. Windows stay the same size when moving between high-DPI and regular monitors.

These two problems are two of the biggest reasons I don't use Ubuntu (or any Linux) desktop (I use a macbook with a headless Ubuntu Server box and, when necessary, X11 forwarding over ssh).

Does it understand "I want 2x magnification on my 15" 4k laptop display, but not on my 43" 4k monitor"? Windows 10 decidedly does not, so I have to switch manually every time I switch display (just forget using both together), and it then tells me to close all my work and log out and in again to make scaling consistent between UI elements on screen.

Yes it does. It even remembers different window sizes and locations for different monitor configs :)

Huh? On Win10Ent I've got both of my displays set to different scaling factors and changes take effect immediately (like, as soon as I release the slider).

It works for me, with one annoying caveat. I have a set of regular 1920x1080 monitors on my desk at 100% scaling. My laptop has a 4k screen, and when I plug it in, I have it set to turn off that screen.

I have to log out when I plug/unplug or the windows will end up blurry or the wrong size.

Have you ever tried shouting at Microsoft about this?

I know they have a bad track record of not listening, but I think things might be different now, they seem to be a bit more receptive to feedback, particularly with the beta updates.

Or maybe I'm remembering the prerelease "hai where r the bugz halp" back when Win10 was not yet RTM...

This is exactly what I mean.

Yes it does, sometimes. But you can configure it as well. I think they used predefined lists of hardware though. EG if name contains tv then scale is 1

Pretty much. Works just fine when I hook my 15" laptop up to my 130" projector.

It's a bit weird to drag things onto my 4k TV through HDMI and try to track my microscopic mouse pointer to the tiny window to maximize my video, but otherwise works well. I suspect I could fix that in settings somehow though.

On newer macos shaking the mouse back and forth makes the pointer get larger (so you can find it).


KDE has a similar feature: When you hold Ctrl+Win, it will draw revolving circle segments in black and white around the cursor to allow you to find it. It looks like this: https://imgur.com/a/67wfI (You'll have to imagine the cursor inside these circles. My screenshot utility won't include it in the image for some reason.)

Heh...I think Windows 3.11 already had that feature (Ctrl -> Circle zooming in to mouse) :)

have you considered swapping out to a BIIIG mouse pointer? that's what I do on my home 65" HTPC/ TVPC :)
