[2.0.28] Nvidia GPU only used when on X11 driver

[phro]

When I launch Factorio on Steam (installed via Flatpak on Fedora Atomic Sway) with Steam launch options

Code: Select all

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia %command%

and the video driver set to X11, Factorio is launched on the Nvidia GPU (albeit with some stuttering during the menu simulation of attacking biter nests with PLD, as well as running at half-resolution on a 4K monitor). nvidia-smi output:

However, when launched with the Wayland driver (which respects the scaling properties of Wayland and operates on a 4K monitor at full resolution), the Nvidia GPU is no longer active. nvidia-smi output:

Given that no other settings were changed, I expected to be able to use the Nvidia GPU with the Wayland driver, especially since I am able to with the X11 driver on sway (presumably through xwayland?).

Thanks!

Hi,

Could this be related to viewtopic.php?f=29&t=119246&sid=b82768d ... 0f1c98b29c? It starts correctly on Wayland outside of Steam but when started from Steam it (appears) to attempt to use nouveau (for me, maybe for you it falls back to intel?) instead. Try starting steam from CLI and see if it looks similar to the linked bug.

Yes, please try the standalone release and see if it makes a difference.
