Does this currently work?

[botiapa]

I'm trying to launch sway with wlroots-eglstreams. I'm using the git version, so I have the newest one compiled sway version 1.6-94e041b5 (Sep 13 2021, branch 'master').

But I'm getting the following error:

00:00:00.001 [ERROR] [sway/main.c:60] !!! Proprietary Nvidia drivers are in use !!!
00:00:00.005 [ERROR] [wlr] [backend/backend.c:442] Failed to open any DRM device
00:00:00.010 [ERROR] [sway/server.c:55] Unable to create backend

Also, I'm wondering whether wayfire works with this patch? Thanks for your response in advance.

EDIT: I managed to start both of them, I just needed to start the kernel with the drm option. I'm not sure how usable it is though, since on wayfire every window (probably xwayland?) is just a black rectangle.

Can you elaborate? What kernel param did you pass, exactly? I have tried a few times over the last month to get this working and get roughly what you show...

Please check your permissions on dri card device. Mine are: ~ > ls -l /dev/dri/card0 crw-rw----+ 1 root video 226, 0 сен 14 00:21 /dev/dri/card0 And what groups you are in: ~ > groups libvirt users video uucp storage kvm disk audio

I did not try wayfire (will do), but in sway all apps including X work with HW acceleration just fine

For me everything besides gitkraken work flawlessly (but that's not this project specific issue, I have it on gnome too)

I guess now that I look more closely, I see that it's just a different error. I'll open a new bug, sorry for any noise.

So I managed to make sway work, however wayfire can only display wayland-native applications. XWayland applications only show a black rectangle.

[anyputer]

Wayfire shows GL applications as black here, next to XWayland... but it's almost amazing other than that!

[g4gg433]

Can confirm above. Under sway everything so far tested works flawlessly.

Under wayfire there are two major problems: -XWayland apps just show a black rectangle -Wayland native applications take like 10 seconds to show a window only Chromium shows up instantly with --disable-gpu flag (this seemingly is also the case on sway but only for GTK applications, electron wayland shows up instantly)

Either this is a problem with wayfires implementation or nvidias rendering. Under GNOME all of this works flawlessly after setting GNOMEs dconf kms-modifier to true.

EDIT: This seems to be a problem with the rendering. MPV also shows a black rectangle despite using the config that works as a wayland native window under GNOME (gpu-context=wayland opengl-es=yes)

To add more info. It seems to me (who has no clue about Wayland rendering architecture) that sway is directly writing the client pixels as it receives it while wayfire is applying transforms (the graphical effects). Nvidia wayland only works for applications that can either disable gpu support (as explained for Chromium) or use "opengl-es" (or opengl-desktop for chromium/electron). Wayfire problably just does not check for this (why should it anyway I guess) and as thus it just renders a black window just like mpv does on GNOME if you do not append --opengl-es=yes
