Natron will not load and has an opengl error

Software Natron
1

I am new to natron and when i try to open it i get this error:

“Error while creating OpenGL context: GLX: Failed to create context
Natron requires at least OpenGL 2.0 with the following extensions so the viewer works appropriately:
GL_ARB_vertex_buffer_object,GL_ARB_pixel_buffer_object”

so i have tried reinstalling as a snap and flatpak and then through apt

i tried running it in a terminal and got this output:

Please help! Thanks!

It’s a problem regarding gpu driver (Mesa → Iris). Use the linux portable install to test.

What it says in terminal?
lsb_release -a
&
lshw -C video

Also does this work?
Go to your natron installation folder.

cd /home/your-natron-folder
MESA_LOADER_DRIVER_OVERRIDE=i965 ./Natron

the natron folder is empty

Use the official installer. https://github.com/NatronGitHub/Natron/releases/download/v2.4.0/Natron-2.4.0-Linux-64.tgz

After installation, the Natron folder should be in your home directory. If giving the same errors then try in terminal:

cd ~/Natron-2.4.0
MESA_LOADER_DRIVER_OVERRIDE=i965 ./Natron

ok that worked

Thanks man

It means you are affected by a new headache intel VGA users are suffering from in Linux distro recently. Deb forums are trying to solve a workaround.
Mainly your VGA driver is not 10th gen iris supported. Which will crash many programs. Better make it global to use legacy driver which is supported up to 9th gen. Type in terminal:

echo 'export MESA_LOADER_DRIVER_OVERRIDE=i965' >>~/.profile

Then restart.

Probably just issues with the Natron snap/flatpak.

Seems like VLC and other GL depended apps are also affected:
