According to Stackoverflow the error messages seem to indicate missing or broken graphics drivers:

libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast

Can you (re-)install the graphics drivers for your system and try again?

Same issue as #27494 ?

[lundybernard]

I was able to install Godot via Steam, and it runs successfully.
no system changes, and I confirmed that the snap installed version still fails as described above.

[ShyRed]

This is interesting... 🤔

Can you give it a shot and try the version of the official website, too?

[lundybernard]

yes, the official binary also runs without any errors. looks like it is specific to the snap install

> ./Godot_v3.1-stable_x11.64 
OpenGL ES 3.0 Renderer: GeForce GTX 1060/PCIe/SSE2

I got same issue on Ubuntu 18.04.2 with Nvidia GTX 970 drivers 415.
Compiled and downloaded Godot, works good.

exact same issue with ubuntu 18.04 running nvidia driver 418.67 and CUDA Version: 10.1.

I also have the exact same issue running steam:

$ steam
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast

$ godot
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast

According to https://github.com/ValveSoftware/steam-for-linux/issues/6116 the issue is related to nvidia not bundling 32 bit run time libraries anymore. As the binary Godot_v3.1.1-stable_x11.64 downloaded from https://downloads.tuxfamily.org/godotengine/3.1.1/Godot_v3.1.1-stable_x11.64.zip works as expected, can it be the case that the binary does not rely on 32 bit libraries while the snap install does?

also error message when using Godot from Snap
axel@redz:~$ godot

libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast ERROR: initialize: Condition ' !fbc ' is true. returned: ERR_UNCONFIGURED At: platform/x11/context_gl_x11.cpp:157.

I can confirm, Snap store version is generating the error.

1. Reinstalled nVidia drivers, did not work
2. Installed 64 bit version from official website, works perfectly

Tested on Ubuntu 18.04.1 with latest updates

[mattiaswerner]

Affecting me as well on a fully updated 18.04, with a 970 gtx and tested nvidia drivers from 415 to 440.

@mattiaswerner Thanks for confirming this bug :slightly_smiling_face:

Since this issue isn't stemming from an official Godot distribution, I'll close it. Please report issues related to the Snap here.
