Xorg usually ships with a different input driver, IIRC. Libinput is the default in Wayland and works seamlessly; Xorg actually needs a wrapper (xf86-input-libinput). Haven't personally used it, just what I've heard.

No copy-paste is a non-starter for me as well, and probably the largest single reason why I still am on i3-gaps. I still like wallpaper mostly because it's nice to add some light transparency to console windows. I3-gaps, for me, was initially because I had a very, very old computer only. This thing had been retired by a corporation three years prior; ancient i3 CPU. With i3-gaps, it ran nice and snappy; on Windows 10, it largely choked. I've appreciated it ever since.

One of the biggest draws is keyboard-friendliness: you don't have to use a mouse to navigate, ever. Nice for those of us who already prefer programs like vim that allow keyboard usage, and can increase productivity. It's also good for multi-window setups (having more than one open), though some people who use tons of windows use bspwm (represents windows with a binary tree).

Noveau sucks, unfortunately. Performance is bad, and you can't load custom firmware like you could with older cards (signing problems). I respect the effort the developers have made; any other driver would be of excellent quality had this much effort been put into it. But Nvidia keeps on being a jerk about it. Easy to say don't support Nvidia, but at the present moment they have the fastest consumer cards on the market.

Sway was the reason I chose a Radeon card to my office workstation. Been running Sway from Github since beginning of this year and it is very stable, fast and great experience, supporting my old i3 configuration as-is.

Now I know my next home gaming computer will also have a Radeon card.

P.S. Put a monthly donation for Sway. Really appreciate the work!

Twofold: for many, it just looks nice. But for me, having a little margin in between things helps me visually distinguish and makes it easier to look quickly at different windows. This is actually helped with a wallpaper, because it further accentuates the borders of windows. I guess a magenta outline on every window would technically serve the same purpose (the sort of thing you might see on a high-contrast UI), but it's a little less gaudy and a little more visually appealing this way.

The desktop number 5 with cmus, alsamixer and a terminal music visualizer with gaps and transparency for eye candy.

Not everything needs to have a real use case!

Again, this is what I've heard; never used it myself (mostly because of the issues you mentioned; I'm unwilling to give up copy-paste and hidpi). With that said, X11 is quite arcane. I3 is still good, or at least for me. Not going to try to proselytize here. I mostly switched because I had to use a completely ancient computer for a while, and I needed to use a tiling wm to get decent responsiveness.

In what sense does Wayland have better hidpi support than X?

> lack of DPI support in X

Even back in 2002 RandR supported obtaining screen size information in pixels and millimeters which can be used to calculate DPI... or actually, what people really want when mentioning "DPI support", an automatic way to scale the windows.

How the window scales is up to the toolkit to implement and is independent of window system and really, even independent of screen size/DPI since some users (e.g. due to sight problems) may want their windows to be scaled even on "low DPI" monitors (the whole DPI thing is just a default setting).

The main problem i see with X here isn't some technical inability, but a way for window managers to notify other clients that they should change their scaling (since the window manager is in a better position to know what scaling each window should use - especially when you want different scaling per monitor, which again can be independent of DPI since you may want a large scale for a wall mounted TV even if the DPI would be very low) - essentially something like a new _NET_WM_SCALE window property for EWMH clients and window managers.

A 5px gap between windows is a drop in the bucket, but adds a lot in terms of aesthetics.
