From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Wayland windows can apparently vsync to multiple monitors at once at different refresh rates (lemmy.max-p.me)

Neat little thing I just noticed, might be known but I never head of it before: apparently, a Wayland window can vsync to at least 3 monitors with different refresh rates at the same time.

I have 3 monitors, at 60 Hz, 144 Hz, and 60 Hz from left to right. I was using glxgears to test something, and noticed when I put the window between the monitors, it'll sync to a weird refresh rate of about 193 fps. I stretched it to span all 3 monitors, and it locked at about 243 fps. It seems to oscillate between 242.5 and 243.5 gradually back and forth. So apparently, it's mixing the vsync signals together and ensuring every monitor's got a fresh frame while sharing frames when the vsyncs line up.

I knew Wayland was big on "every frame is perfect", but I didn't expect that to work even across 3 monitors at once! We've come a long, long way in the graphics stack. I expected it to sync to the 144Hz monitor and just tear or hiccup on the other ones.

TL;DR Wayland is good

Super apparent performance on my ancient Chromebook with barely any resources. Beautiful animations that make it look like a modern laptop, well, until ram runs out. It can run about 3x as much stuff compared to stock ChromeOS. Love this with Pipewire, Linux a/v is honestly better than both osx and windows now and I'm so impressed. Can even do pro audio type stuff where you route the a/v from one app to another. It's worth losing all the network ability that X11 has
