NVIDIA (495) on sway tutorial + questions (Arch-based distros)

@rogueai @aacebedo it seams that they’re aware of this issues with PRIME devices (cf. this issue from the egl-wayland repo).

Unfortunately, no ETA yet.

I’m working on the NVIDIA driver + installation for NixOS. Can someone help me understand validation steps for confirming that EGL, EGL+Wayland, and various scenarios involving GBM are all working properly?

The following steps have taken place:

  1. Upgrade to latest 495 stable driver.
  2. Ensure that /etc/egl/egl_external_platform.d/15_nvidia_gbm.json is installed next to 10_nvidia_wayland.json.
  3. Ensure that nvidia-drm_gbm.so is in a configured mesa gbm search path and is a symlink to libnvidia-allocator.so.495.44.
  4. Launch sway with the appropriate env args.
  5. (edit: also, patch wlroots/sway around the RGB check)

While I have nvidia-sway (see below) working, with Sway running, I still experience:

  1. flickering
  2. Steam does not launch
  3. eglinfo only partially works, the “wayland platform” and “x11 platform” sections still fail

Questions:

  1. What should I expect to see from eglinfo?
  2. Have I missed any key steps here to getting nvidia->gbm->sway->egl to work?
  3. What other steps can I take to ensure that the nvidia driver is mostly installed correctly for NixOS users? (For example, until I noticed recently we weren’t even putting the egl_external_platform.d files in the right place.)

^^ (note, how can I confirm Xwayland is built appropriately?)

edit: ignore the versions in the log file, I don’t patch that out in my overlay that runs tip of tree builds apparently.

This lack of support for VDPAU is only on XWayland apps or also on Wayland native apps? I’m having some trouble activating video hardware acceleration on native apps such as Firefox.

VDPAU is completely unavailable on Wayland at the moment. NVENC/NVDEC are available but they’re not available in any browser.

Thanks for the reply! Has NVIDIA confirmed it’s something they are working on or we just have to cross fingers?

I don’t think Nvidia has said anything about developing VDPAU for Wayland yet :/

This user seems to be doing some work on this front but nothing from Nvidia themselves yet. Hopefully we see some action soon now that they’ve given us GBM at least.

I’m also noticing a lot of flickering on Sway with the new GBM support. Any idea how to fix it? I searched the Internet and found some solutions that did not work for me. Mostly it appears when I scroll or switch between apps. Or when a lot of stuff happens on the screen.

I tried so far:
WLR_DRM_NO_ATOMIC=1

disabling VRR
__GL_VRR_ALLOWED=0
__GL_GSYNC_ALLOWED=0

Nothing helped :/
Beside the flickering it runs awesome and I really appreciate having Sway again!

Problem about external monitors on prime machines (HP zbook studio) is still there with beta 510…

Could someone create a sway-nvidia fork (and possibly a package in AUR) where we could have the current, best GBM config for the latest version of the proprietary NVIDIA driver? The ‘installation guide’ (GRUB config, env vars, etc) would be nice too.

Or if there already is one, could someone point me to it please?

Currently, everybody uses so many different configs that no one really knows which are working the best. A Git repo would be nice to keep it all in one place.

I’d create one, but this is my first time with NVIDIA GPU, first time with Arch Linux, and I never contributed to anything related to GPUs. :)

Given the current state of the Nvidia GBM driver, which doesn’t play well with the original wlroots, I’d still recommend sticking to the wlroots-eglstreams project for now. Uninstall sway and wlroots, then install it (and sway-git) with yay wlroots-eglstreams-git. The author keeps this branch pretty up-to-date with the original wlroots and I have found it much more stable than trying to use GBM for now.

Had anyone managed to fix ‘argb8888 && xrgb8888’? I cant get any logs out of sway and this is all i have, running 510-39-01.

sway-git and wlroots-git don’t have the error for me

Currently the two linux distros i use are Void and Gentoo. I dont think i cam do that but will it be the same as building from master?

I built from source on github!

after installing arch and all the necessary -git stuff, and 510 driver

Xwayland sucks. i will go back to regular X, thanks for your help.

I’m loving Sway on Nvidia so far! Multiple monitors work great, there’s no screen tearing when scrolling on Firefox, resizing apps is fast, and games run wonderfully.

However, I’m running into major issues with every Electron app I run, and some XWayland ones such as xeyes. There are countless artifacts, including z-fighting, flickering, and weird redrawing issues.
I did notice all Element apps seem to run in XWayland (despite me setting the Ozone flags in ~/.config/electron-flags.conf), but forcing Wayland through directly passing the arguments --enable-features=UseOzonePlatform --ozone-platform=wayland to the program (Element Desktop as an example) does not seem to fix the rendering issues.

Here’s an example of the redrawing issues that occur with xeyes:

Has anyone else encountered these issues? Is there a current workaround? It’s pretty much the only thing keeping me from switching to it fully.

Maybe be helpful, Arch installing of Sway together to Gnome:

I followed the above video but wlroots-eglstream-git didn’t seem to do the job for me (RTX 2080 Super): sway was stalling on startup.
Using wlroots-git i/o wlroots-eglstream-git (which by the way doesn’t seem to be maintained anymore) did the trick. I’ve had flickers in the beginning but they seem to have disappeared after a reboot.
Thanks a lot to all this thread’s participant for putting all this together :)

This is becoming my favourite environment. The only issues that prevent me using this all the time (instead of i3) are:

If anyone got to the bottom of the electron issue please share! Looks like screen sharing is in the works.

Anyone test out the newest drivers to see if there is improvement, maybe there will be more supports with the kernel module being open sourced
