 Posted: Wed Dec 27, 2023 10:28 pm Post subject: Cannot start Sway. I use Nvidia |
 |
|
Hello everyone
I'm trying to start Sway but I keep getting errors like "EGL_NOT_INITIALIZED", "DRI2: failed to load driver", and "Failed to create renderer". I have an Nvidia graphics card and I have set nouveau in my video cards USE flags.
Let me know if I should provide more info and thanks for your time  |

Welcome to Gentoo,
please try by starting sway --unsupported-gpu - look here https://wiki.archlinux.org/title/sway#Installation
or edit as root /usr/share/wayland-sessions/sway.desktop
if you using Openrc / elogind dbus-run-session sway --unsupported-gpu
and maybe you also need some of the following variables which can be set in .profile file in your users Home - create as user, e.g. touch .profile (<<< there's a DOT at the beginning).
| Code: | # NVIDIA
export WLR_NO_HARDWARE_CURSORS,1
export LIBVA_DRIVER_NAME,nvidia
export __GLX_VENDOR_LIBRARY_NAME,nvidia
export GBM_BACKEND,nvidia-drm
export __NV_PRIME_RENDER_OFFLOAD,1
export __VK_LAYER_NV_optimus,NVIDIA_only
export WLR_DRM_NO_ATOMIC,1
export NVD_BACKEND,direct
# FOR VM and POSSIBLY NVIDIA
export WLR_RENDERER_ALLOW_SOFTWARE,1
# nvidia firefox (for hardware acceleration on FF)?
# check this post https://github.com/elFarto/nvidia-vaapi-driver#configuration
export = MOZ_DISABLE_RDD_SANDBOX,1
export NVD_BACKEND,direct
export EGL_PLATFORM,wayland |
you can also use it as a script file which you have to tell sway to initiate at start.
here is an example https://github.com/crispyricepc/sway-nvidia/blob/main/wlroots-env-nvidia.sh
and read the WiKi - you'll find most infos https://github.com/swaywm/sway/wiki
i'am not sure, because i use AMD.
EDIT:
or try with Hyprland - it is a fork of Sway with nice eye candy
https://wiki.hyprland.org/hyprland-wiki/pages/Nvidia/
try with the dots from https://github.com/JaKooLit/Hyprland-Dots

do you have: nvidia-drm.modeset=1 on your kernel command line?

First of all thanks for the detailed answer. I've tried all of that but it did not work. Even Hyprland crashes on start.  |

fwiw you don't need to set that when USE=wayland is set on nvidia-drivers (it's set by default in nvidia.conf then). USE=wayland on nvidia-drivers is of course required for other reasons too, I do assume it's set globally if you're using wayland.
That aside, I hope this isn't some dual gpu / optimus setup, that tend to confuse everything esp. with wayland. The situation should be a little bit better with nvidia-545 though, so you could try 545 if not already (~testing-only due to being a non-production branch).
Haven't tried sway with nvidia-drivers in like a year, so haven't kept up with quirks to help more with that. Not sure but don't recall I needed to set/change anything to make it "at least" start (with my single gpu) except passing the (now renamed) my-next-gpu-wont-be-nvidia option  Not that there wasn't other quirks after that (like needing to disable hw cursor). |

Out of interest, have you tested whether a non-wlroots-based compositor works? |

plasma/kwin and gnome/mutter tend to always work fine given upstreams care to keep nvidia working to some degree (I give both a quick try whenever I stabilize new nvidia-drivers in a passthrough VM I use for this). They both work "out of the box" without anything special for me, except that gdm can be a bit picky about letting you start it with wayland when using nvidia (may try to force Xorg), so I use sddm for both to avoid the hassle.
Otherwise there's also weston for non-wlroots I guess, but I never really played with that one and not sure how it fares with nvidia.
End of the day, I still use Xorg myself though, will reconsider in a few years  |
