system76-scheduler VS mustang

> I don't know what Popos does to make it more "gaming focused" than vanilla Ubuntu.

They have a few changes, chief among them being the PopOS scheduler which I find to be quite effective: https://github.com/pop-os/system76-scheduler

The desktop itself is a weird custom-baked x11/GNOME customization you won't really get on Ubuntu. Not many distributions can claim the title of being truly "unique", but PopOS does deserve the title in my opinion. Even still it wouldn't be my choice for gaming, but I'll defend it's identity as something more than another GNOME/Debian spin.

Power management kinda doesn't work on Linux. There are very minimal rules once you disconnect from AC, and most of the time you'll switch into high-usage mode when it isn't needed. There's not a clean way to fix this, to my knowledge; the Linux scheduler stack is just kinda based around desktop and server hardware.

That being said, I also use Linux on my Thinkpad anyways. There are decent enough workarounds that I can keep my system up for 5-6 hours when away from AC:

- Switching into battery-saver mode will keep clock speeds down, which generally reduces power usage (as long as you aren't slamming the cores)

- tlp can help if your hardware has power-draining characteristics (I don't use it, my defaults are good enough)

- Using an auto-nicer can keep your system feeling responsive when in power saving mode: https://github.com/pop-os/system76-scheduler

So... caveat emptor, YMMV. Linux is far from the most efficient OS away from the wall, but with a little bit of configuration I feel like my system does indeed work as a "normal laptop".

ran rtcqs as a replacement for realtimeconfigquickscan at the suggestion of Brock from System 76 (thank you Brock ily). As it kept suggesting that I build a custom kernel and I would rather switch back to Windows than do that, I checked github issues on system76-scheduler, found this: https://github.com/pop-os/system76-scheduler/issues/99. Seems to fit with everything I know about the situation.

system76-scheduler

For starters, you will get better performance using the stock (System76 kernel) but that's another conversation. To solve your specific issue you will need to install the missing dependencies with this command

And installing and configuring system76-scheduler, it works by allocating the most resources to the window you have in focus, so say a full screen game or a browser you have open. Keep in mind that it only works with the POP-Shell extension and if you don't use it, you will need this one instead.

If you start a game with game mode, then system76-scheduler lowers the game priority and makes your FPS lower: https://github.com/pop-os/system76-scheduler/issues/57

It would be great for Rust to have a Linux target that doesn't use libc, but from what I've read, not many people are interested in this.

Found this as well: https://github.com/sunfishcode/mustang

Some discussion here: https://github.com/bytecodealliance/rustix/issues/76

On Linux there has been some attempts to get exactly this solutions, most notibly https://github.com/sunfishcode/mustang but the topic did not seem to fetch a prominent position on the supported feature list.

For Linux, Mustang already exists because Linux has a stable syscall API

Why bother with a libc at all, when you can skip it entirely on Linux!

Mustang is a project which is able to run some non-trivial programs written in Rust, such as ripgrep, without using any libc, on Linux.

Mustang is one way to take care of the tiny amount of "C" that runs before main().

This is more a Rust question than a Zig question. In Rust, the choice of a specific libc (or to not use a libc) is part of the "target", for example many hardware platforms have gnu/musl/none targets. See also relibc or mustang for pure-rust alternatives. Each libc alternative require some work to integrate into Rust.

There's a separate project for that, called Mustang. It's built on top of rustix and provides all those things. It's not super mature yet, but it is able to run ripgrep by itself: https://github.com/sunfishcode/mustang
