classic opengl application on 19.04 fail to find gl drivers

[Alan Pope 🍺🐧🐱 🦄]

On Ubuntu 19.04 using nVidia GTX 980M GPU and latest drivers from the archive (nvidia-drivers-418) a classic snap is unable to draw GL windows.

Steps to reproduce

* Boot Ubuntu 19.04 and update it on an nvidia system with the binary driver
* snap install godot --classic
* snap run godot

Expected result

A window appears

Actual result

Application fails to start. Output includes:

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

Note: Same snap works on 18.04 with GL in a VirtualBox VM (on the 19.04 host) and on 18.04 with Intel GPU on bare metal.

I'm running the proprietary nvidia drivers at release 390, on 19.04.

[Zygmunt Krynicki (zyga)]

I had a look at the snap in question (Godot) and looked at how it is built. I believe, though I'm not sure of it, that without changing how it is build and how GL drivers are injected we cannot address this issue.

I can reproduce the issue with my GTX Titan X, proprietary nvidia drivers at 418 and Ubuntu 19.04 with snapd master. Same error messages

Godot is a classic snap and cannot benefit from the mount namespace arrangement provided by snapd. As hinted in the previous comments, it's best if you bring this is up with Godot developers. The snap lists https://github.com/godotengine/godot/issues as their contact page.

(Commenting here instead of a new issue since the symptoms/error messages seem close)

In case it matters, the CMake snap (specifically the cmake-gui app) also reports the same error message on startup. It is also a classic snap, but in this case the app does appear to run successfully. Can't comment on whether performance is affected or if it might lead to artefacts in some cases.

Seen on an Ubuntu 18.04 VM under Parallels on a macOS host. Also same error message appears on a CentOS 7 VM under Parallels on the same macOS host.
