System Information
Operating system: Ubuntu 19.04
Graphics card: NVidia PRIME Laptop (GeForce GTX 960M (GPU 0))

Blender Version
Broken: 2.80 installed via flatpak
Worked: 2.80 installed via download of blender-2.80-linux-glibc217-x86_64.tar.bz2

Short description of error

When starting blender from flatpak i get the error:

Error! Unsupported graphics card or driver.
A graphics card and driver with support for OpenGL 3.3 or higher is required.

Exact steps for others to reproduce the error

On a PRIME laptop with the graphics card mode set to "NVIDIA" try to start blender 2.80.

Complete console printout on startup:

The program will now close.

BTW, the snap version also works ok. Only issue via flatpak.

The reason the upstream tarball works is that it runs directly on the host (not in a sandbox) and as a result has direct access to the drivers. The snap might be in that case as well.

You use the proprietary nvidia driver?

If yes, can you run the following on your machine?

$ flatpak list --all | grep -i nvidia

[hcw70]

hcw@nvidion:~$ flatpak list --all | grep -i nvidia
nvidia-390-116	org.freedesktop.Platform.GL.nvidia-390-116		1.4	flathub	system
nvidia-390-77	org.freedesktop.Platform.GL.nvidia-390-77		1.4	flathub	system
nvidia-430-40	org.freedesktop.Platform.GL.nvidia-430-40		1.4	flathub	system

For snap i had to do
snap install --classic blender
So it may have full access.

On the host i use nvidia-driver-430 from ubuntu.

Indeed, that gives it full access, as it runs essentially unsandboxed. Flatpak doesn't have an unsandboxed mode, we need to poke appropriate holes in the sandbox to get things working.

On the host i use nvidia-driver-430 from ubuntu.

Ok, and you have that extension installed: org.freedesktop.Platform.GL.nvidia-430-40

At this point I will need to investigate a bit, not sure why this doesn't work for you. 😕

What does the output of

flatpak run --command=ls org.blender.Blender /usr/lib/x86_64-linux-gnu/GL/ 

give you?

[hcw70]

hcw@nvidion:~$ flatpak run --command=ls org.blender.Blender /usr/lib/x86_64-linux-gnu/GL/ 
glvnd  nvidia-430-40  OpenCL  vulkan

@RexoWeb that comment is off-topic as the article talks about Windows and doesn't apply to Flatpak.

It's also not something we should recommend: downloading a random OpenGL library from a Google Drive and replacing the normal one with it is terrible security practice. Who knows what that library really does?

Finally, the fact you point to an article on your own website and then yourself add positive reactions to your comment makes me wonder if you're not just a spammer.

Please do not do any of that here any more.

Hi there 👋 This issue has been open for a while....

@hcw70 could you please test if the error persists with the latest published version?

[hcw70]

@plafue Blender now starts with version 2.93.0 ok.
But preferences says it is unable to find my NVIDIA gpu.

[hcw70]

Ok, gpu did not work in snap also....
But after reboot, all is fine.
So this was a problem of my gpu....
