Yeah, I personally still have a lot of 60 Hz panels. One of my favorites is a 43" 4K IPS. I don't think I will be able to get that at 120+ Hz any time soon. Of course, this isn't a huge deal to me. The additional latency is n

Latency and throughput are very different things. However, it's worth noting that the comparison here is with and without compositing. If you were using compositing already on X11 (I believe XFCE offers it with "Desktop Effects&qu

Currently, the Wayland protocol itself doesn't have a standard solution to global shortcuts. Instead, it's being pushed to the XDG Desktop Portal API, under the org.freedesktop.portal.GlobalShortcuts service: https://fl

The point is that we can improve latency of even old machines by simply attaching a display output that supports a higher refresh rate, or perhaps even variable refresh rate. This can negate most of the unavoidable latency of a compositor,

Mouse cursor latency and window compositing latency are two separate things. I probably did not do a good enough job conveying this. In a typical Linux setup, the mouse cursor gets its own DRM plane, so it will be rendered on top of the des

Essentially, the only reason to go over 60 Hz for desktop is for a better "feel" and for lower latency. Compositing latency is mainly centered around frames, so the most obvious and simplest way to lower that latency is to shorten

> Can the compositor replicate the input-to-pixel latency of uncomposited x11 on low-end devices or is that a class of performance we just have to sacrifice for the frame-perfect rendering of wayland? I think this is ultimately correct.

Here's my PoV: - Having a single X server that almost everyone used lead to ossification. Having Wayland explicitly be only a protocol is helping to avoid that, though it comes with its own growing pains. - Wayland-the-Protocol (soun

I hope that XFCE remains a solid lightweight desktop option. I've become a huge fan of KDE over the past couple of years, but it certainly isn't what you would consider lightweight or minimal. Personally, I'm a big proponent

Apparently, they are using gVisor, which when applied properly, should make a pretty good isolation primitive.

This would not be surprising at all! An impressive amount of work has gone into making the Linux VFS and filesystem code fast and scalable. I'm well aware that Linux didn't invent the RCU scheme, but it uses variations on RCU libe

Sounds more like the VFS layer/FS is the bottleneck. It would be interesting to try another FS or operating system to see how it compares.

I think this is just solving a different but related problem. Symbol versioning enables you to make observable changes to the behavior of some library like a libc while providing backwards compatibility by providing the old behaviors indefi

Well yes, but you'd be spawning a wineserver and running wineboot and all kinds of baggage on top, all for the very simple task of mapping and executing a PE binary, and of course you would still wind up needing ELF... for the Wine loa

I mean something a bit different. I mean using PE binaries to store Linux programs, no Wine loader. Of course, this is a little silly. It would require massively rethinking many aspects of the Linux userland, like the libc design. However,
