=x11-drivers/nvidia-drivers-550.40.07 comes with 64-bit nvidia-drm_gbm.so in /usr/lib64/gbm/nvidia-drm_gbm.so but there's no 32-bit /usr/lib/gbm/nvidia-drm_gbm.so library, despite that abi_x86_32 is set in the USE flags. this affects CEF/Chromium applications like Steam and Gamescope which causes flickering and more visual bugs under Wayland. I tried setting GBM_BACKENDS_PATH=/usr/lib64/gbm,/usr/lib/gbm in /etc/environment but that results in a black screen.

First I hear of someone having issue with that. For what it's worth, the (upstream) NVIDIA installer *also* does not create the 32bit symlink even if you ask it to install 32bit libraries. It also lack a 32bit egl-gbm. The ebuild is basically doing what upstream does. Are you sure it's the cause of your issues and not just a message that happens to be displayed? Given NVIDIA also doesn't ship with a 32bit version of egl-gbm, I'm not convinced it'd be usable even if the symlink exists (it may however silence load error messages, but not necessarily solve your problems). Anyhow you can try it with: mkdir -p /usr/lib/gbm && ln -s ../libnvidia-allocator.so.1 /usr/lib/gbm/nvidia-drm_gbm.so If doing that doesn't help, then having the ebuild do it wouldn't help anything. If it does help, I don't mind manually doing the symlink.

If it does help, I don't mind manually doing the symlink. I think it has to do with the unavailable 32-bit egl-gbm but I'm not really that sure, but flickering and graphical glitches take effect for some reason. Also, I tried using your workaround and got this error: MESA-LOADER: failed to open nvidia-drm: /usr/lib64/gbm/nvidia-drm_gbm.so: wrong ELF class: ELFCLASS64 (search paths /usr/lib64/gbm, suffix _gbm)

That it would cause flickering sound rather unlikely to me. I could understand if things just straight up didn't work, not "work badly". (In reply to breaktrace from comment #4) > (In reply to breaktrace from comment #3) > Sorry, I realized I just set the wrong file and path, I'm going to symlink > properly in a sec Don't forget to get rid of GBM_BACKEND_PATHS if you still have it, that it's looking in lib64 sounds odd.

I got rid of GBM_BACKEND_PATHS in /etc/environment, but I got the same error again: MESA-LOADER: failed to open nvidia-drm: /usr/lib/gbm/nvidia-drm_gbm.so: wrong ELF class: ELFCLASS64 (search paths /usr/lib/gbm, suffix _gbm) I'm on a GTX 1050 and I was using KDE Plasma 5 and had flickering/graphical bugs on Steam, and also I got an "libEGL warning: egl: failed to create dri2 screen" error which is pretty awkward. I'm on KDE Plasma 6.0 RC2 now and the same issues occur.
Well I don't know what you're running into but, as far as this bug goes, it doesn't sound like adding the symlink would help then. Perhaps it's even making things worse from the sound of it? Unless got a mess going from tinkering with this and it's hard to tell what's going on anymore.
wrt flickering, I do recall a few threads about 550 drivers (maybe 545 too, albeit I seen more reports about 550), e.g. https://forums.developer.nvidia.com/t/280484/2 Not that I can do anything about that, you could either try nvidia-drivers-535 or go back to Xorg for now. Note that 550 is a unkeyworded beta.
Well, I'll just go ahead and close this for now. Don't want to differ from what the official NVIDIA installer is doing without some confirmation that it's at least useful for something and not just a guess that it may or may not help (don't use/test steam myself). Likewise for multilib egl-gbm (NVIDIA doesn't ship a 32bit version for it, but egl-gbm is open source so it'd be possible to build it -- but again, only if can get some confirmation that it's useful). Imagine it may possibly(?) get used by wine now that it's getting native wayland support, but most/all other 32bit-only applications are old and wouldn't use wayland in the first place. Wine has the new alternate option to enable USE="wow64 -abi_x86_32" which doesn't need ELF multilib for 32bit too.
