Sofware renderer used with Nvidia graphics on linux

Post by egyptianbman »

Unfortunately, the latest version of Factorio doesn't recognize the GPU on Linux and resorts to software rendering, leading to an unplayable 1-3 FPS. I see in the log that Factorio does claims to have initialized the OpenGL:

But unfortunately, no matter what combinations of flags I try, it just won't utilize the gpu. I do see a factorio process in nvidia-smi consuming gpu memory -- around 1.5GB -- but it doesn't actually use it for rendering.

I've seen a few related threads, but nobody seems to have been able to find a solution. I'd appreciate any help in trying to resolve this issue; thanks!

Re: Unplayable on Linux

Post by Honktown »

I see a few references to Nvidia+Wayland or Wayland+distro being unable to use OpenGL properly:

https://wiki.gnome.org/Initiatives/Wayland/NVIDIA
There is currently no accelerated GLX support when running a GNOME Wayland session no top of the NVIDIA drivers, meaning X11 OpenGL applications will use software rendering.
https://devtalk.nvidia.com/default/topi ... ipe-only-/
The nvidia driver currently only supports software rendering (llvmpipe) when used in Xwayland.
https://bugs.launchpad.net/ubuntu/+sour ... ug/1823516

Don't know if the nouveau driver would work any better. One post from ~2 years ago said it just straight froze their system on login:
https://www.reddit.com/r/kde/comments/7 ... or_nvidia/
I have mods! I guess!

Sorry for the delayed response. I never got any e-mails -- and I see now that I can check a box to be notified of replies.

I'm not using wayland, I use I3 which still uses X. It did work before, before the revamp.

I've tried this on both Ubuntu 18.04 and have now switched to Arch on the same machine. The same issue still exists. I've tried setting force-opengl in ~/.factorio/config/config.ini to true to no avail.

The game is initialized with correct GPU driver, so from the game's side rendering should just be accellerated by GPU.

I am convinced it is some driver/Linux issue related to having multiple GPUs in the system. I don't know how to help.
You could try to change preferred screen option in Graphics settings and test if it starts working on different screen. (Or maybe just try dragging the game window to different screens).

Thank you for responding! You may be right regarding the multiple screens. Unfortunately, moving the game from one monitor to another (from one gpu to another) made no difference except when the game was on monitors run by "the other gpu" -- not the gpu that the game loaded on, colors were off, etc. I tried updating the configs to load from different screens, no help.
