Bug 942486 – x11-drivers/nvidia-drivers game doesn't launch on dGPU when called on through wayland

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description Tyler 2024-10-29 23:12:33 UTC]

Since updating my desktop and downgrading the nvidia-drivers package due to the security vulnerability I have been unable to launch games on my dedicated GPU in steam flatpak. They all launch from the AMD iGPU.

This was working up until I updated. I can confirm regular steam works fine with the below command, but it doesn't do anything in flatpak anymore:

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia %command%

Reproducible: Always

Actual Results:  
Game does not launch on dedicated GPU.


Operating System: Gentoo Linux 2.15
KDE Plasma Version: 6.2.2
KDE Frameworks Version: 6.7.0
Qt Version: 6.7.2
Kernel Version: 6.11.5-gentoo-dist (64-bit)
Graphics Platform: Wayland
Processors: 32 × AMD Ryzen 9 7950X 16-Core Processor
Memory: 117.5 GiB of RAM
Graphics Processor: AMD Radeon Graphics

>downgrading
have you tried upgrading to 565.57.01? It's not affected by the vulnerability

[Comment 3 Tyler 2024-10-31 00:25:37 UTC]

I have not, because it's not available as an update in ~amd64 when performing a standard upgrade.

It is though? Assuming you've done emerge --sync since October 25, can see it for ~amd64 there [1]

Yeah I see it on there but it’s not being pulled in as an update. Maybe I’m on a bad mirror.

[Comment 6 Tyler 2024-10-31 14:21:21 UTC]

Alright I had to make a few new ~amd64 keywords to pull in the package.

Can confirm the new driver with updated flatpak fixes my issue.

Nice.

fwiw it's a beta driver which are not due to be stabled (we only stable production branches like 550, current 565 wasn't even meant to be keyworded due to being a beta but 560 getting driver pushed the need for it), so it'll be a while before we stable a >=565-based driver.

550 lacks a lot of wayland improvements and its users are generally expected to either use Xorg or have a simple single gpu setyo at the moment, not much we can do about that.

560 driver getting dropped pushed the need for it*
