Bumblebee VS wlroots-eglstreams

Have you tried Bumblebee? That and this page was helpful for me. I don't remember if Bumblebee ever worked for me, but a lot of people have success with it.

Ok, I figured out what was wrong: apparently my computer uses Nvidia Optimus which uses my Intel GPU to save power. And so I have to tell it to uses Nvidia through Bumblebee which I haven't figured out completely yet.

If I remember right, the Bumblebee project is open source for hybrid Intel/nVidia laptop GPUs. The open source drivers never gave me the problems that the proprietary nVidia drivers had. https://www.bumblebee-project.org/

This are magical parameters for me, i.e. I have 0 idea what it does in fact. I know however that this solves acpi problems with modern-ish optimus laptops: https://github.com/Bumblebee-Project/Bumblebee/issues/764

How does Bumblebee work with sway?

The Bumblebee wiki then says that you can run games by first exporting DISPLAY=:8 and then running them with primusrun or optirun as normal: https://github.com/Bumblebee-Project/Bumblebee/wiki/Multi-monitor-setup

Ah yeah, I have similar feelings.

BumbleBee was promising at one time:

But seems kind of dead now.

I actually got a chance to develop against some proprietary API and i don't blame them for not wanting to support proprietary drivers , But there is at least one guy maintaining a fork for nvidia so you can try your luck there.

The developer of the EGL stream fork of wlroots wants to migrate to the original version, maybe if he will become a maintainer there could be a change in the status quo, or he can maintain a fork with fixes.

Sway uses wlroots, which is one of I believe 3 wayland libraries (wlroots, smithay and taiwins). It just happens that sway (and most other compositors such as river, hikari, dwl) use wlroots, which doesn't care about nvidia. There is wlroots-eglstreams if you want to try that.

That is not entirely true, there is a fork of wlroots which supports NVIDIA's proprietary driver's EGLStreams implementation, which works fine with Sway and probably other WMs too, see https://github.com/danvd/wlroots-eglstreams.

In the meantime you can use wlroots-eglstreams

Install a fork of wlroots (the library used by Sway to do pretty much everything).

Also I know about a fork a guy did for wlroots that adds support for egl streams but this is far from ideal, it's a interesting job nonetheless https://github.com/danvd/wlroots-eglstreams

If your a technical person , you can give wlroots-eglstreams a try (it's a fork of wlroots adding nvidia support).

As of now you can run Sway with wlroots-eglstreams, which is a work-in-progress fork of wlroots, working as drop-in replacement, see https://github.com/danvd/wlroots-eglstreams and https://aur.archlinux.org/packages/wlroots-eglstreams-git/.
