Bumblebee VS wlroots

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.

>barrier has been unmaintained for a long time.

As if not having new features added for 2 years makes it stop working? barrier is perfectly fine on normal linux desktop installs. I actually use synergy 1.x personally which has been "unmaintained" for much, much longer. Except synergy 1.x will compile and run on anything from windows 98 to ubuntu 5 to debian 12. You can't get a waynergy or inputleap to compile on an OS more than 2 years old. And even then, as you say, it's crapshoot if the particular wayland will have libei; many like sway are actively hostile to it and never will: https://github.com/swaywm/wlroots/issues/2378

It looks like they actually patched it to filter those modes out, so presumably it worked out of the box and was considered undesirable: https://github.com/swaywm/wlroots/issues/3038

I haven't experienced any of those. The video game performance hit may be due to vsync, but I don't play games so I haven't noticed.

You can however use tinywl. It is an example Wayland compositor that can't do more than displaying one application.

Sway/wlroots has implemented this, but I can't find any discussion for KDE.

wlroots is archived on github. Is it abandoned? Just saying, that only means they moved git hosts :-D

A lot of compositors are based no the wlroots lirbary. So they are still sharing the development effort and have a common base, its just in the form of a library rather than a display server.

gamescope use wlroots
